    CustomEase

    Are your animations meant to feel playful? Robotic? Slick? Realistic? If they had a voice, what would they sound like? To become an animation rock star, you must develop a keen sense of easing because that's what determines the style of movement between point A and point B. GreenSock's new CustomEase frees you from the limitations of canned easing options. Create literally any ease imaginable. Zero limitations. CSS animations and WAAPI offer cubic-bezier() which is great but with only two control points it's impossible to create more complex effects like bouncing, elastic, wiggles, rough/jerky eases, etc. Plus you can't make an ease return to its starting values (like a ball jumping into the air and falling back to the ground with a bounce). Features Unlimited anchors and control points. Copy/Paste any SVG <path> (including directly from Adobe Illustrator). Use CSS cubic-bezier() values (For example, from cubic-bezier.com). Editor has snapping, undo, sample code and other conveniences. Start with any standard ease and customize it. getSVGData() method turns any ease into SVG <path> data for display at the size you define. Extremely optimized for runtime performance. Free for anyone with a GreenSock account. Reading Ease Curves, Editing, and Using CustomEase Here's an in-depth video tour that'll get you up to speed with exactly how to use CustomEase: Ready to play? Check out the new Ease Visualizer with CustomEase support. Edit the curve as much as you want: Download CustomEase Get CustomEase by creating a FREE GreenSock account which gets you access to our community forums plus you’ll receive our exclusive “GreenSock Insider” email series (you can unsubscribe anytime). Use the widget below to sign up (or if you’re already logged in, you’ll get immediate access to the download zip containing CustomEase). Note: CustomEase is not in the github repository or CDN; it's only available for download at GreenSock.com. [loginwidget]
  2. SplitText is an easy to use JavaScript utility that allows you to split HTML text into characters, words and lines. Its easy to use, extremely flexible and works all the way back to IE8. Although SplitText is naturally a good fit for creating HTML5 text animation effects with GreenSock's animation tools, it has no dependencies on GSAP, jQuery or any other libraries. .videoNav { color:#555; margin-top: 12px; } 0:00 Intro 0:21 SplitText solves problems 2:01 Basic Split 3:34 Configuration options 6:35 Animation View the JS panel in the Codepen demo above to see how easy it is to: Split text into words and characters. Pass the chars array into a TweenMax staggerFrom() tween for animation. Revert the text back to its pre-split state when you are done animating. Additional features and notes You can specify a new class to be added to each split element and also add an auto-incrementing class like .word1, .word2, .word3 etc. View demo You don't have to manually insert <br>tags, SplitText honors natural line breaks. SplitText doesn't force non-breaking spaces into the divs like many other solutions on the web do. SplitText is not designed to work with SVG <text> nodes. Learn more in our detailed SplitText API documentation. Please visit our SplitText Codepen Collection for more demos of SplitText in action. Where can I get it? SplitText is a membership benefit of Club GreenSock ("Shockingly Green" and "Business Green" levels). Joining Club GreenSock gets you a bunch of other bonus plugins and tools like ThrowPropsPlugin as well, so check out greensock.com/club/ to get details and sign up today. The support of club members has been critical to the success of GreenSock - it's what makes building these tools possible.

    GSDevTools

    Your animation workflow is about to get a major boost. GSDevTools gives you a visual UI for interacting with and debugging GSAP animations, complete with advanced playback controls, keyboard shortcuts, global synchronization and more. Jump to specific scenes, set in/out points, play in slow motion to reveal intricate details, and even switch to a "minimal" mode on small screens. GSDevTools makes building and reviewing GSAP animations simply delightful. Get Started Load the JavaScript file //be sure to use a path that works in your dev environment Requirements GSDevTools requires TweenMax (well, actually just CSSPlugin, TweenLite, TimelineLite, AttrPlugin which are all included in TweenMax) version 1.20.3 or higher. It also uses Draggable under the hood, but in order to minimize hassle for end users, Draggable is included inside the GSDevTools file itself. How do I get it? GSDevTools is available to Club GreenSock members ("Shockingly Green" and above). Just download GSAP with the bonus files zip from your Dashboard. Try GSDevTools for free on CodePen. FAQ Why is my Global Timeline 1000 seconds long? That means you've probably got an infinitely repeating animation somewhere. GSDevTools caps its duration at 1000 seconds. Scrubbing to Infinity is awkward. Does loading GSDevTools impact runtime performance? Since it must monitor and record the root timeline, yes, there is a slight performance hit but probably not noticeable. Keep in mind that usually you'll only load GSDevTools while you're developing/reviewing your animations and then remove it when you're ready to launch, so ultimately it shouldn't be much of a factor anyway. Why isn't GSDevTools in the CDN or Github repo? Because it's a membership benefit of Club GreenSock. It's a way for us to give back to those who support our ongoing development efforts. That's why we've been able to continue innovating for over a decade. See https://greensock.com/why-license for details about our philosophy. Does GSDevTools work with other animation libraries? Nope, it depends on some unique capabilities baked into the GSAP architecture. What will I do with all the time this tool saves me? Take up a new hobby, ponder deep philosophical questions, make cookies - it's up to you.

    GSAP 2.1 Released

    There are plenty of large and small updates in GSAP 2.1; here are a few highlights... Advanced staggers Advanced staggering makes it surprisingly simple to get rich, organic timing effects with very little code. Each tween's start time can be distributed according to any ease and/or based on how close each element is to a position in the list. For example, you can have things emanate outward from the "center" or a certain index. It'll even accommodate grids, complete with auto-calculated columns and rows (great for responsive layouts)! The interactive demo below explains it all visually (notice there's an embedded video explanation too): See the Pen Advanced Staggers in GSAP by GreenSock (@GreenSock) on CodePen. So setting up an advanced stagger is as simple as: TweenMax.staggerTo(".yourClass", 2, { scale:0.1, y:40, stagger:{ amount: 2, //total seconds to divide up among staggers from: "center", //or an index value. Determines where staggers originate grid:"auto", //or [columns, rows] ease: Power1.easeIn //determines spacing } }); Parts of the advanced staggering features were prompted by suggestions from GSAP users inspired by Julian Garnier's API in anime, so we tip our hat to his efforts. He's a great contributor to the animation community. MorphSVG type:"rotational" There's an entirely new type of morph that leverages rotational and length data to move anchors and control points which can deliver cleaner, more intuitive morphs. Plus it completely eliminates kinks that can occasionally creep in with linear interpolation. The video below explains. Watch the video To tap into this new style of morphing, just set the type:"rotational" TweenMax.to("#shape1", 2, { morphSVG:{ shape:"#shape2", type:"rotational" } }); Or set it as the default to affect all morphs: MorphSVGPlugin.defaultType = "rotational"; //default is "linear" Demo 1: preventing kinks See the Pen MorphSVG type:'rotational' for preventing kinks by GreenSock (@GreenSock) on CodePen. Demo 2: more natural morphs See the Pen MorphSVG type:'rotational' for more natural morphs by GreenSock (@GreenSock) on CodePen. Fixing odd results by declaring a custom origin The default origin is 50% 50% which usually works great, but sometimes the rotations around that point look odd, as shown below. In cases like this, it's best to experiment and set your own custom origin to improve things even more. We created a findMorphOrigin() utility function which is in the codepen below (and you can copy it into your own) which allows you to simply feed in a start and end shape and then it'll superimpose an origin that you can drag around and see exactly how it affects the morph! In the demo below, go into the JS panel and un-comment the findMorphIndex() line and you'll see exactly how this works. Drag the origin around and watch how it affects things. See the Pen MorphSVG: fixing origin weirdness by GreenSock (@GreenSock) on CodePen. Note: you must load Draggable for this to work. So to set a custom origin, it would look like: TweenMax.to("#shape1", 2, { morphSVG:{ shape:"#shape2", type:"rotational", origin:"20% 60%" //or to define a different origin for the start and end shapes, "20% 60%,45% 30%" } }); Is the new type:"rotational" a silver bullet for making every morph perfectly intuitive? No, but it's a great option that delivers more natural morphs in many cases. MorphSVG canvas rendering SVG is fantastic, but sometimes developers have a canvas-based project (often for rendering performance reasons). They haven't been able to leverage the intuitive morphing that MorphSVG provides in a highly-performant way...until now. The new MorphSVG plugin allows you to define a render function that'll be called every time the path updates, and it will receive two parameters: rawPath [array]: A RawPath is essentially an array containing an array for each contiguous segment with alternating x, y, x, y cubic bezier data. It's like an SVG <path> where there's one segment (array) for each "M" command; that segment (array) contains all of the cubic bezier coordinates in alternating x/y format (just like SVG path data) in raw numeric form which is nice because that way you don't have to parse a long string and convert things. For example, this SVG <path> has two separate segments because there are two "M" commands: <path d="M0,0 C10,20,15,30,5,18 M0,100 C50,120,80,110,100,100" /> So the resulting RawPath would be: [ [0, 0, 10, 20, 15, 30, 5, 18], [0, 100, 50, 120, 80, 110, 100, 100] ] For simplicity, the example above only has one cubic bezier in each segment, but there could be an unlimited quantity inside each segment. No matter what path commands are in the original <path> data string (cubic, quadratic, arc, lines, whatever), the resulting RawPath will ALWAYS be cubic beziers. target [object]: the target of the tween (usually a <path>) This means you can even render morphs to super high-performance engines like PixiJS or anything that'll allow you to draw cubic beziers! Demo: MorphSVG canvas rendering See the Pen MorphSVG canvas rendering by GreenSock (@GreenSock) on CodePen. Here's an example of a tween and a render function that'd draw the morphing shape to canvas: var canvas = document.querySelector("canvas"), ctx = canvas.getContext("2d"), vw = canvas.width = window.innerWidth, vh = canvas.height = window.innerHeight; ctx.fillStyle = "#ccc"; TweenMax.to("#hippo", 2, { morphSVG:{ shape:"#circle", render:draw } }); function draw(rawPath, target) { var l, segment, j, i; ctx.clearRect(0, 0, vw, vh); ctx.beginPath(); for (j = 0; j To set a default render method for all tweens: MorphSVGPlugin.defaultRender = yourFunction; Got questions?

    GSAP 2.0 Released

    We've been getting requests for better support of modern build tools. With version 2.0 we're pleased to announce a switch to ES modules via NPM which should make your building, bundling, and tree shaking even smoother. Don't worry, the UMD/CommonJS flavor is still available and the CDN serves the same browser-friendly files as always. If terms like "UMD", "ES Modules", and "tree shaking" leave you scratching your head, fear not - GSAP 2.0 will work like a champ for you (as usual). There are no syntax, API, or browser-support changes. None. The major version bump was primarily due to the switch to ES modules for NPM users, that's all. DOWNLOAD GSAP NOW NPM, ES Modules, Webpack, oh my! Modern bundlers like Webpack and Rollup just love to snack on ES modules these days, usually grabbing them from NPM. So GSAP 2.0 is extra delicious covered in its chocolatey ES module outer shell. (If you're not using a bundler or NPM, skip this section entirely) npm install gsap Then you can import individual classes like: import TweenMax from "gsap/TweenMax"; import Draggable from "gsap/Draggable"; TweenMax includes (and exports) many of the commonly-used classes so you can also do this: import { TweenMax, TimelineLite, Power2, Elastic, CSSPlugin } from "gsap/TweenMax"; (TweenMax includes TweenLite, TimelineLite, TimelineMax, CSSPlugin, RoundPropsPlugin, BezierPlugin, DirectionalRotationPlugin, AttrPlugin, and all eases except CustomEase, CustomWiggle, and CustomBounce) As a convenience, there's also an "all" file that imports/exports every GSAP tool (except members-only bonus plugins), so you can do this: import { TimelineMax, CSSPlugin, ScrollToPlugin, Draggable } from "gsap/all"; IMPORTANT: if your animations aren't working as expected, it's likely an issue with tree shaking which can be easily resolved by referencing any plugins you're using. Read more. UMD/CommonJS If your environment doesn't accommodate ES modules yet, don't worry - we've got you covered. There's a "umd" directory that contains...you guessed it...regular old ES5 UMD (Universal Module Definition) versions of the files which are compatible with pretty much everything (RequireJS, Browserify, etc.). So you could import them like: //get the UMD versions. Notice the "/umd/" in the path... import { TweenMax, Power2, TimelineLite } from "gsap/umd/TweenMax"; import ScrollToPlugin from "gsap/umd/ScrollToPlugin"; import Draggable from "gsap/umd/Draggable"; What about bonus plugins like MorphSVGPlugin? Obviously we can't distribute the members-only bonus plugins via NPM, so all you need to do is log into your GreenSock account and download the latest zip which has a "bonus-files-for-npm-users" folder with the bonus plugins. Then just plop that into your project, like maybe in your /src/ folder (or wherever) and import them directly. For example, to save some typing you could rename the "bonus-files-for-npm-users" to simply "gsap-bonus" and put that in the root of your project and then: import MorphSVGPlugin from "./gsap-bonus/MorphSVGPlugin"; import SplitText from "./gsap-bonus/SplitText"; You could certainly put the bonus files in /node_modules/gsap/ if you prefer, but most people don't like doing that because it makes things less portable/updatable. There's a brand new page in the docs dedicated to NPM usage. NEW: Custom rounding increments in RoundPropsPlugin Have you ever needed to round animated values to the nearest 10 or hundredth? With the new object syntax in RoundPropsPlugin, you can round properties to various custom increments, not just integers! Simply pass in [property]:[increment] pairs like so: TweenLite.to(element, 5, { x:600, y:100 roundProps:{ x:10, //round x to nearest increment of 10 y:0.1 //round y to nearest increment of 0.1 } }); Watch the video Demo See the Pen RoundPropsPlugin Update by GreenSock (@GreenSock) on CodePen. NEW: SplitText "specialChars" SplitText recognizes a new specialChars property that allows you to specify an array of special characters to protect. This is typically used for multi-character symbols like in some languages where there are pairs (or sometimes even 4 characters) combined to form a single character. See the Pen SplitText with specialChars feature by GreenSock (@GreenSock) on CodePen. No need to do this for most emoji's, though, because those are already supported natively in SplitText!

    GSAP 1.20.0 Released

    Here are some of the highlights of the GSAP 1.20.0 release... yoyoEase Now you can specify an ease for the yoyo (backwards) portion of a repeating TweenMax animation. Set it to a specific ease like yoyoEase:Power2.easeOut or to flip the existing ease, use the shortcut yoyoEase:true. TweenMax is smart enough to automatically set yoyo:true if you define a yoyoEase, so there's less code for you to write. Score! Animate CSS Variables (custom properties) See the Pen CSS Variables Demo by GreenSock (@GreenSock) on CodePen. Emoji support in TextPlugin 'Nuf said. ...and more There are quite a few little improvements and bug fixes as well, which are listed in the changelog at the github repository. Download GSAP today.

Flash has served as the de facto standard for banner ads for more than a decade. Firefox also blocked Flash after major security issues were discovered and Facebook's security chief called for Adobe to kill Flash once and for all. Amazon says it will no longer accept any Flash ads after September 1. Clearly Flash is on its way out of web browsers. Advertisers can no longer afford its liabilities. Now what? Modern browsers are remarkably capable of handling slick animations natively using HTML, JavaScript, and CSS (collectively referred to as “HTML5” or just “H5”), making them the obvious choice as the tag-team successor to Flash. No more plugins. However, a few barriers are clogging up the transition. Some are technical, some are political, and some have to do with a glaring lack of information. Let's address things head-on, identify some solutions, and get things moving in the right direction. GreenSock has a rich heritage in the banner ad industry, serving as its most popular animation library in both Flash and HTML5. In fact, it’s one of the fastest-growing JavaScript tools on the entire Internet and it was originally born out of banner-specific needs. We obsess about animation in the browser, studying the technical challenges, performance benchmarks, and workflow. Consequently, we’re in a unique position to lend a hand during this transition and perhaps illuminate the path forward. 40 kilobytes? Are you kidding? Years ago, when bandwidth was a tiny fraction of what it is today, the ad industry codified a set of standards for banner ad file sizes. A common limit was 40kb (sometimes even 30kb) including all images, fonts, animations and scripts which Flash compressed into a single amazingly small swf file. Technically each publisher determines its own file size policies, but almost everyone looks to the IAB (Interactive Advertising Bureau) as a standards-setting body, like the W3C for web browsers. The IAB exists to help guide the industry but they don't mandate or enforce anything. When Flash ruled the banner ad landscape, certain file size specs were recommended by the IAB and the system worked well. However, the technology landscape has changed drastically. Bandwidth, page size, and banner budget over the yearsBandwidth (Mbps)Banner budget (kb)Page size (kb)2008200920102011201220132014201540kb33Mbps40kb1,795kb Year Bandwidth (Mbps) Banner budget (kb) Page size (kb) Jan 1, 2008 5.86 40 312 Jan 1, 2009 6.98 40 507 Jan 1, 2010 9.54 40 679 Jan 1, 2011 10.43 40 788 Jan 1, 2012 12.7 40 1081 Jan 1, 2013 15.62 40 1529 Jan 1, 2014 20.83 40 1622 Jan 1, 2015 32.78 40 1795 Page size (kb) Since 2008, average bandwidth has grown by a factor of 5.6 which is remarkably on-pace with the growth of the average web page size (5.7), but the IAB has been cautious about declaring HTML5 specs due to all the complexities involved. They released a set of HTML5 guidelines in 2013, but omitted any file size specs, saying only that HTML5 ads weigh "more" than swf ads. Without specs, many publishers clung to the safe limits of yesteryear. The gatekeepers who impose the 40kb budgets often do not have the authority or wherewithal to allow more than what the latest IAB spec dictates. Consequently, developers are forced to shoehorn HTML5 banners into archaic Flash specs which isn't what the IAB intended. This must change. From our vantage point, fear is driving the industry. Publishers and networks are afraid to raise the file size limits without IAB approval. Some do it anyway, but disagree on exactly how much, leading to wild variations. Developers have no choice but to build for the least common denominator in their ad campaign which is either totally unclear or ends up being the dreaded creativity-crushing 40kb. (UPDATE: The IAB released a draft of its new HTML5 specs.) HTML5 is fundamentally different...embrace that HTML5 banners often weigh 3-5 times as much as a Flash swf but far too many people myopically focus on the aggregate total file size. They miss the unique strengths of HTML5 technology that we should be exploiting - shared resources and browser caching. These have a tremendous impact on loading time and overall performance which is the whole point of the file size limits anyway! Flash compiled all assets into a single swf meaning that if 10 different banners on a site all used a certain library, it got baked into each and every swf. End users paid the file size price 10 times. Multiply that by millions of ads and it gets pretty crazy. In HTML5, however, a library can be dropped onto a CDN (content delivery network) and shared among all banners, thus end users only load it once and it’s completely "free" thereafter...for all ads pointing at that CDN...on all sites. This is a BIG deal. It means that common animation chores like the requestAnimationFrame loop, timing, sequencing, intelligent GPU layerizing, lag smoothing, compatibility workarounds, performance optimization, etc. can be extracted and shared among them all (much like what the Flash Player did for swf files). The unique banner-specific code can be much more concise, reducing overall load times and improving performance. File size limitations should be applied to the banner-specific assets, excluding the shared resources that drive common functionality. Imagine how silly it would have been if the 17MB Flash Player download was included in the aggregate file size for each swf banner. Ad networks and publishers can put a certain subset of tested-and-approved libraries onto their CDNs and exempt them from file size calculations. We're thrilled to see industry leaders like Advertising.com/AOL, Google DoubleClick, Flashtalking, and Sizmek already taking this approach with GSAP. This strategy allows developers to avoid burning hours manually cooking up their own proprietary libraries to fit within the ad specs. Ad networks and publishers win because load times (and costs) are lowered and it's easier to troubleshoot problems when a common toolset is used. They reap the benefits of all the compatibility and performance optimizations in tools like GSAP. End users get ads that perform better, load faster, and look more appealing. Animation technologies and approaches For those tasked with building HTML5 banners, the choices are perplexing. Is it best to use a visual IDE like Adobe Edge Animate, Google Web Designer, or Tumult Hype? Even Flash is capable of outputting HTML5 content. These tools can make building ads easier (especially for designers who don’t want to write code), but a common complaint is that the resulting output is bloated and slow, making them ill-suited for banner ads. Some networks explicitly state that they won't accept ads built with these tools. We'd love to see the visual tools mature and export concise, performant, ad-friendly code because plenty of designers aren't comfortable hand-coding banners yet. Ideally, they'd tap into GSAP under the hood so that designers and developers could collaborate on the same files without worrying about runtime redundancies. There are also network-specific banner-building tools but their proprietary nature makes them impractical for many campaigns. If an agency uses one network’s proprietary tool and then their client asks to run the ad on another network too, it must be rebuilt. Learning how to use each network's proprietary tool can be cumbersome. Hand-coded animations are usually much lighter-weight, performant, and universally accepted, but building them requires a particular skill set. And which underlying technologies should be used? CSS animations? jQuery? GSAP? CreateJS? Once again, answers vary wildly among ad networks and publishers. The goal of this article isn't to provide an in-depth review or comparison of the various tools. Each has its own strengths and weaknesses, but let's briefly touch on some of the major runtime animation technologies: CSS transitions and CSS animations - these are supported in all modern browsers, but not IE9 or earlier. They're cheap from a file size standpoint and they perform well. For simple animations like button rollovers, they're great. However, file size rises quickly and things get cumbersome when you attempt even moderately complex animations. Simply put, they will take longer to build, they won't work in some older browsers, there are bugs (particularly when animating SVG elements), and certain tasks are outright impossible. Additional reading: https://css-tricks.com/myth-busting-css-animations-vs-javascript/ and http://greensock.com/transitions/ and https://css-tricks.com/svg-animation-on-css-transforms/ jQuery - it was never intended to be a robust animation tool, so jQuery suffers from poor performance and workflow issues. Most ad networks strongly advise against using it. GSAP is up to 20x faster. Additional reading: http://greensock.com/jquery/ CreateJS - Adobe Flash can optionally export to this canvas-based library. You can't just publish existing Flash banners to CreateJS (you must do some conversion work and leverage JavaScript instead of ActionScript) but for designers who are already used to the Flash interface, this can be a boon. One down side to canvas-based libraries is that you lose accessibility (the browser sees it as essentially a blob of pixels), but that's probably not a top priority for banners. File size can also become a concern (possibly mitigated by CDN standardization). You can use GSAP to animate CreateJS content. Additional reading: http://createjs.com Zepto - like a lightweight version of jQuery that uses CSS transitions under the hood for animations. Zepto is better than jQuery for banners, but it suffers from similar workflow issues as well as the inconsistencies/bugs inherent in CSS transitions/animations (like with SVG transforms). Active development seems to have stalled. Additional reading: http://zeptojs.com Web Animations - a new spec being worked on that has a lot of promise, but it just isn't a realistic contender at this point because it is in flux and several browser vendors remain noncommittal about ever supporting it. The polyfill has performance problems. Additional reading: http://w3c.github.io/web-animations GSAP - Widely recognized as the performance leader, GSAP solves all kinds of real-world animation problems from browser inconsistencies to workflow headaches (far too many to go into here). The Flash banner ad community is full of designers and developers who use GSAP daily, making it much easier to transition to HTML5; no new syntax to learn. Ongoing development and support have a solid track record for over 7 years. Additional reading: http://greensock.com/why-gsap/ Recommendations Based on our experience and the results from our survey, we suggest the following: Standardize a few JavaScript libraries Ideally, the IAB would equip the community with a short list of recommended libraries that get CDN-ified and exempted from file size calculations. Historically, the IAB has been extremely reluctant to officially endorse any third party tools. That's understandable - it could be seen as playing favorites or unfairly excluding someone's favorite library. However, without specific recommendations, the HTML5 landscape is so fractured and complex that it will result in a free-for-all (which is basically what it is now). The IAB can set the tone and move the focus away from aggregate total file sizes and into the modern era that leverages shared resources and browser caching to deliver excellent performance. It is imperative that this list of "recommended" libraries be very short, otherwise the caching impact will be diluted. The IAB can run their own independent tests and look at performance, features, compatibility, support, workflow benefits, and overall industry demand to determine which libraries get recommended. Of course we feel strongly that GSAP belongs on that list because: It is the top performer. It has widespread industry acceptance, both in Flash and HTML5. It's recommended by Google, used by the biggest brands in the world, etc. It is framework-agnostic, super flexible and robust, able to animate anything. It is professionally supported, yet free to use in banner ads. Modernize file size specs Given the 5.6x growth factor of bandwidth and page size since 2008, it seems entirely reasonable to adjust the old 40kb limit to 200kb (5x) for the modern HTML5 era. This is entirely consistent with some in-depth testing that has been done recently aimed at identifying the file size threshold at which real-world users perceive a dip in performance. The results showed that the threshold was upwards of 250kb. Combined file size isn't the only issue that contributes to slow load times; the number of server requests can have a significant impact. A single 300kb file can often load faster than 200kb split among 20 files. HTML5 banners can't realistically mash everything into one file, though. Doing so would kill the benefits of caching and resource sharing. So a reasonable compromise seems to be a 10-file maximum. Sprite sheets can be used to combine images. Given all the factors, we'd recommend the following for standard (non-rich media) ads: 200kb combined total (gzipped) Maximum of 10 files. Any additional must be loaded "politely" (after the parent page finishes loading) Shared CDN resources like GSAP don't count toward these totals. Some have suggested slicing the 200kb standard limit into two parts - a 50kb initial load, and then the rest "politely" loads. However, we advise against this for standard (non-rich media) ads because it unnecessarily complicates the design and production process as well as QA and enforcement. Rich media ads will likely require more files and kb than the limits mentioned above, and those should be polite-loaded. By "rich media", we mean ads that contain video or expand or perform API calls (like feeding the viewer's zip code to a backend script), etc. Update documentation and guidelines It is surprisingly difficult to get answers to some of the most basic questions when preparing a banner ad campaign for even the biggest networks and publishers. What are the file size limits? Which libraries can be used? Do CDN resources count against the total file size? Is there a network-specific CDN link for common libraries? Online docs either have outdated information or none at all related to HTML5. Drop support for IE8 Legacy IE support is not just painful for developers, it's exceedingly expensive for advertisers. Certain effects are outright impossible, so creatives must learn about the IE8 pitfalls and adjust their designs. Developers are forced to rebuild entire portions, implement workarounds and perform extra testing, all to accommodate a tiny fraction of the web audience who probably don't represent the demographic that advertisers are targeting anyway. This was never an issue for Flash, but it's a HUGE issue for HTML5 because it relies on native browser technologies that are absent from older browsers like IE8. Our recommendation is to draw a line in the sand and drop support for IE8 for sure, and potentially even IE9. Consider SVG instead of iframes Displaying ads inside an iframe is nice for security, but it forces ads into a strict rectangular space (ruling out fancy overlays with transparency/mask effects that show the main web page behind) and there's a performance price too. SVG is widely supported and it has some excellent transparency/masking capabilities, plus it can serve as a single container for an entire ad (see Chris Gannon's blog post and video)! Further testing needs to be done to better understand the performance and security implications, but it certainly seems like a worthwhile contender. Create a gallery of sample banners and templates Rather than pouring over specs and instructions and then building something from scratch, most developers prefer to analyze banners that already conform to the standards and use one as a template for their own project. Each network has different API's and ways you must track clicks, etc., so it would be lovely if each one provided a gallery of demos at each standard size. Codepen.io is a great place to host a collection because it's so easy to see (and edit) the HTML, CSS, and JS as well as the result all in one place. Developers can simply click the "fork" button and start producing their own version of that banner immediately in the browser. Codepen even integrates nicely with crossbrowsertesting.com for easy QA. Adjust client expectations As the industry transitions from Flash to HTML5, clients must be made aware of the design, budget, and schedule implications. HTML5 banners take more time to produce and test, therefore they will be more expensive. Plus there are certain effects that were easy in Flash but are virtually impossible in HTML5, so creative expectations need to be adjusted as well. Common GreenSock Questions With the broader discussion out of the way, let's narrow our focus to GreenSock for a moment and address some of the most frequently asked questions: Which networks support GSAP? All networks that we're aware of allow GSAP, and most even exempt its file size from the ads and host it on their CDNs. Google DoubleClick recommends GSAP for complex animations. Here's a breakdown of how some of the major players stack up: Allows GSAP Excludes GSAP from file size calculation* Hosts GSAP on CDN Advertising.com/AOL YES YES YES Google DoubleClick YES YES YES Flashtalking YES YES YES Sizmek YES YES YES Flite YES YES YES Cofactor YES YES YES AdWords YES YES YES *Unless publisher objects which is uncommon TweenMax is too big! Where's TweenNano? Let's face it: TweenMax (the most robust tool in the GSAP suite) is overkill for many banners that are only doing simple fades and movement. Wouldn't it be smart for GreenSock to create a super-small animation engine that's targeted at banners and only has the basic features? In the Flash days, we did exactly that and called it "TweenNano". It weighed about 2kb. On the surface, it sounds like a great idea but there are several reasons we avoided TweenNano in the HTML5 toolset: Caching - this is the biggest factor; loading the JavaScript file is a one-time hit and then the browser caches it, mitigating the entire loading issue on every page thereafter. Realistically, TweenNano must include a subset of TweenLite and CSSPlugin features and weigh at least 8kb; how much longer would it take for the average user to load an extra 25kb for TweenMax? It's not even noticeable (less than one second). So it doesn't seem like a worthwhile tradeoff to rip out all those features just to gain a fraction of a second only the first time it loads, especially for banners where caching and resource sharing could be used so effectively. If networks toss TweenMax.min.js on their CDNs, it effectively becomes "free" (zero load time) very quickly, giving them instant access to all the timeline tools plus a bunch of advanced plugins. Thus it seems smarter to press the full-featured, super-fast TweenMax engine into service rather than a sliced-down TweenNano with limited effects. Performance - GSAP has been engineered with a huge priority on performance which sometimes comes with a file size tradeoff. We could accomplish the same tasks with less code in places, but runtime performance would suffer. We feel strongly that when it comes to animation, it's wiser to pay a small up-front kb tax (only a fraction of a second in most cases) in order to get maximum runtime performance. Animations must look smooth and conserve battery power. Think of it this way: would you rather buy a computer that boots up 2 seconds faster or one that's 30% faster all the time (after it boots)? Flexibility/Creativity - what if you want to animate a non-essential CSS property like boxShadow or slide along a curve or scrub through a timeline? Even if there's just one part of your banner that needs a more advanced feature, it presents a dilemma. Creativity is hampered. Again, the fraction of a second one-time cost difference for TweenMax seems well worth it for the added flexibility and peace of mind. API confusion - years ago, Adobe created a lightweight version of the Flash Player dubbed "Flash Lite" with similar aspirations (bake only the essentials into a lighter weight flavor), but it was a complete failure. One of the problems was that developers couldn't remember which features were available in the regular Flash Player versus Flash Lite. Likewise, TweenNano's feature disparity would create some confusion/frustration. What about creating a tool that lets users select only the features they need, and then it spits out a customized stripped-down version of TweenMax? Again, this sounds appealing, but it would likely lead to worse load times because instead of having one common TweenMax that gets shared and cached, every banner would have its own different (and partially redundant) flavor to load. Ultimately, we're committed to delivering the tools that are needed most, so if the broader industry decides not to leverage shared resources and publishers insist on sticking to all-inclusive aggregate file size totals, we're open to creating TweenNano. Luckily, it looks like there's excellent momentum behind TweenMax getting CDN-ified and exempted from file size limits. In our opinion, that's definitely the smartest approach. What's so special about GSAP? It's beyond the scope of this article to explain all the benefits of using GSAP; see http://greensock.com/why-gsap/ for a summary. If you're still wondering what the big deal is, we'd encourage you to find someone who is proficient with it and ask about their experience. Usually people who take the time to learn it have a "light bulb" moment pretty quickly and never want to go back to using other libraries or CSS. It's difficult to explain to the uninitiated - lists of features don't really do it justice. It's not merely about performance (although that's a biggie) - it's about feeling empowered to animate almost anything you can imagine with minimal code. Do I need a commercial license to use GSAP in banner ads? GreenSock's standard "no charge" license covers usage in banner ads even if you get paid a one-time fee to produce the banners. We fully encourage the use of GSAP in banner ads and beyond. You may want to check out Club GreenSock for some bonus plugins that allow you to easily achieve advanced effects. Is anyone building a GUI for GSAP? A visual tool for building GSAP-based animations is a popular request, and we have been approached by several large and small companies about the possibilities, but there's nothing rock solid to report yet. We hope that companies like Adobe and Google will offer export options from their tools that leverage GSAP as the runtime engine and produce well-formatted, concise code. There's a pretty neat tool called Animachine that's in alpha and can be installed as a Chrome extension. It shows promise, but isn’t entirely stable at this point. There are also several online GSAP-based banner builders: http://html5maker.com/, https://tweenui.com/, and http://www.loxiastudio.com. Where can I get GSAP training? You can have GreenSock come directly to your organization and sit with your team to get them up to speed quickly. We can even convert one of your Flash banners and then teach you how we did it which is an excellent way to learn banner-specific tricks. The Q&A sessions are invaluable. We have limited slots available, though, so contact us as soon as possible to get your event scheduled. There are plenty of other learning resources available: GreenSock's getting started video/article GreenSock's learning resources New GreenSock eBook (published by Noble Desktop) Lynda.com course ihatetomatoes.net course (intermediate/advanced) Noble Desktop class in NYC 02Geek course Egghead.io The GreenSock forums are a fantastic place to not only ask your question(s), but also poke around and see what others are saying. It's one of the best places to learn even if you never ask a question. There are plenty of demos on codepen.io as well. For inspiration, we'd suggest following these people: Chris Gannon Sarah Drasner Petr Tichy Sara Soueidan Diaco.ml Blake Bowen Ico Dimchev UPDATE: The IAB released a draft of its new HTML5 specs and is soliciting public feedback before finalizing the document. The outstanding news is that they agreed with our assessment regarding a 200kb limit for standard ads. The IAB is expected to release an update to its HTML5 Best Practices guide soon which will likely contain a short list of JavaScript libraries that are recommended for exemption from file size calculations. We're confident GSAP will be on that list.
  9. Feature lists are nice, but they can get lengthy and they don't always tell the story in a way that's relevant to you as the developer or designer in the trenches, trying to get real work done for real clients. You hear plenty about theoretical benefits of CSS animations or some whiz-bang library that claims to solve various challenges, but then you discover things fall apart in all but the most modern browsers or the API is exceedingly cumbersome or there frustrating "gotchas".

GSAP The new standard for HTML5 animation replay
  10. GreenSock

    GSAP JS 1.9.0 Released

    New DirectionalRotationPlugin Have you ever tweened rotation to a particular value but wished that you could control which direction it traveled (clockwise or counter-clockwise)? For example, if the current rotation is 170 and you tween to -170, normally that would travel counter-clockwise -340 degrees but what if you prefer rotating 20 degrees clockwise instead? Or maybe you just want it to go in the shortest direction to that new position (20 degrees in this case). This is all possible now with the DirectionalRotationPlugin. Previously, shortRotation was available in CSSPlugin, but there were three shortcomings (pardon the pun): It always went in the shortest direction - it wasn't possible to define a particular direction (clockwise or counter-clockwise). It required using a different property name ("shortRotation" or "shortRotationX" or "shortRotationY") instead of the regular property name ("rotation" or "rotationX" or "rotationY"). It only worked on DOM elements. What if you have a generic object or an EaselJS Shape (or whatever)? The new DirectionalRotationPlugin solves all of these issues. First of all, its functionality is baked into CSSPlugin, so you don't even need to load the DirectionalRotationPlugin if you're only animating DOM elements. The plugin is also included in TweenMax, so there's no need to load a separate plugin there either. Use the new syntax to get the desired behavior - add one of the following suffixes to the value: "_cw" for clockwise, "_ccw" for counter-clockwise, and "_short" to go whichever direction is shortest. Here are some examples: //tweens to the 270 position in a counter-clockwise direction (notice the value is in quotes) TweenMax.to(element, 1, {rotation:"270_ccw"}); //tweens to the -45 position in a clockwise direction TweenMax.to(element, 1, {rotation:"-45_cw"}); //tweens 1.5 radians more than the current rotationX value, and travels in the shortest direction TweenMax.to(element, 1, {rotationX:"+=1.5rad_short"}); If you're tweening a more generic object (anything that's not a DOM element), you can use the DirectionalRotationPlugin. If you pass in a simple value, it will assume you're attempting to tween the target's "rotation" property but you can tween ANY rotational properties of any name by passing in an object with the appropriate properties. Here are some examples: //start with a generic object with various rotation values var obj = {rotation:45, rotationX:0, rotationY:110}; //tweens rotation to 270 in a clockwise direction TweenLite.to(obj, 1, {directionalRotation:"270_cw"}); //tweens rotationX to -45 in a counter-clockwise direction and rotationY to 200 in a clockwise direction: TweenLite.to(obj, 1, {directionalRotation:{rotationX:"-45_ccw", rotationY:"200_cw"}}); As of 1.9.0, shortRotation is deprecated in favor of this new (more flexible and concise) syntax. New AttrPlugin This plugin allows you to tween any numeric attribute of a DOM element. For example, let's say your DOM element looks like this: <rect id="rect" fill="none" x="0" y="0" width="500" height="400"></rect> You could tween the "x", "y", "width", or "height" attributes using AttrPlugin like this: //tuck any attributes you want to tween into an attr:{} object TweenMax.to("#rect", 1, {attr:{x:100, y:50, width:100, height:100}, ease:Linear.easeNone}); You can tween an unlimited number of attributes simultaneously. Just use the associated property name inside the attr:{} object. The AttrPlugin is included inside the TweenMax JS file, so you don't need to load the plugin separately if you're using TweenMax. New TextPlugin This plugin allows you to tween the text content of a DOM element, replacing it one character at a time (or one word at a time if you set the delimiter to " " (a space) or you can even use a custom delimiter). So when the tween is finished, the DOM element's text has been completely replaced. This also means that if you rewind/restart the tween, the text will be reverted to what it was originally. Here is a simple example of replacing the text in yourElement: //replaces yourElement's text with "This is the new text" over the course of 2 seconds TweenMax.to(yourElement, 2, {text:"This is the new text", ease:Linear.easeNone}); If you'd like to use a different delimiter so that instead of replacing character-by-character, it gets replaced word-by-word, just pass an object with configuration properties like this: //replaces word-by-word because the delimiter is " " (a space) TweenMax.to(yourElement, 2, {text:{value:"This is the new text", delimiter:" "}, ease:Linear.easeNone}); Sometimes it's useful to have the new text differentiated visually from the old text, so TextPlugin allows you to assign a css class to the new and/or old content, like this: //wraps the old text in <span class="class1"></span> and the new text in a <span class="class2"></span> TweenLite.to(yourElement, 2, {text:{value:"This is the new text", newClass:"class2", oldClass:"class1"}, ease:Power2.easeIn}); As indicated, defining a newClass and/or oldClass will result in wrapping a <span> tag around the associated text. The TextPlugin is NOT included inside TweenMax, so you'll need to load it separately. Other updates and enhancements in 1.9.0: Added support for hsl() and hsla() colors in CSSPlugin and ColorPropsPlugin Implemented a new (more concise and clear) way to register plugins. Old plugins will still work fine, but most of the new ones in 1.9.0 use the new style of registering which won't work with old versions of TweenLite/TweenMax. Please just make sure all your files are updated. Fixed issue that caused className to be ignored by the autoCSS feature that creates the css:{} wrapper internally. Fixed issue that could cause em not to be translated to px accurately, causing a jump when the start and end units for the tween don't match (like px to em or visa-versa) Fixed backfaceVisibility so that it is properly prefixed when necessary Now setting "float" on a DOM element will work across browsers including Firefox and IE. Worked around issue that caused x/y/z transforms not to work properly if they exceeded 21,474 (or -21,474). Fixed issue that caused values not to be interpreted correctly if a negative number had a relative prefix, like "+=-50px" or "-=-50px" Fixed issue in EaselPlugin that prevented ColorMatrixFilter tweens from working correctly when the starting matrix wasn't an identity matrix Now fromTo() and staggerFromTo() methods have immediateRender set to true by default, just like from() and staggerFrom() always did. This seems like the preferred behavior for most developers, but you can certainly set immediateRender:false on any tween if you prefer that behavior. Now fromTo() and staggerFromTo() tweens that have immediateRender:false will record their pre-tween values (before even implementing the "from" part of the tween) so that if their parent timeline rewinds past the beginning of the tween, it restores values to their originals. Get it now Download the latest version of GSAP using the fancy new download screen, and notice that everything is also available as CDN links as well.

  11. This video walks you through some common problems that professional animators face every day and shows you how GSAP’s TimelineLite tackles these challenges with ease. Although GSAP is very powerful and flexible, the API is beginner-friendly. In no time you will be creating TimelineLite animations that can bend and adapt to the needs of the most demanding clients and art directors. Watch the video and ask yourself, "Can my current animation toolset do this?" Enjoy. Video Highlights Tweens in a TimelineLite naturally play one-after-the-other (the default insertion point is at the end of the timeline). No need to specify or update the delay of each tween every time the slightest timing changes are made. Tweens in a TimelineLite don't need to play in direct sequence; you can overlap them or easily add gaps. Multiple tweens can all start at the same time or slightly staggered. Easily to rearrange the order in which tweens play. Jump to any point of the timeline to finesse a particular animation. No need to watch the whole animation each time. Add labels anywhere in the timeline to mark where other tweens should be added, or use them for navigation. Control the speed of the timeline with timeScale(). Full control over every aspect of playback: play, pause, reverse, resume, jump to any label or time, and much more. Unlike jQuery.animate() or other JS libraries that allow you to chain together multiple animations on a particular object, GSAP’s TimelineLite lets you sequence multiple tweens on multiple objects. It's a radically different and more practical approach that allows for precise synchronization and flexibility. If you are still considering CSS3 animations or transitions for robust animation after watching this video, please watch it again Check out this Pen! If you are wondering what "autoAlpha" refers to in the code above, its a convenience feature of CSSPlugin that intelligently handles "opacity" and "visibility" combined. Recommended reading: Main GSAP JS page Jump Start: GSAP JS Speed comparison Cage matches: CSS3 transitions vs GSAP | jQuery vs GSAP jQuery.animate() with GSAP: get the jquery.gsap.js plugin! 3D Transforms & More CSS3 Goodies Arrive in GSAP JS
  12. GSAP's CSSPlugin is now super-charged to handle some slick new CSS3 properties like 3D transforms, boxShadow, textShadow, borderRadius and clip. Plus you don't need to worry about a litany of vendor prefixes. GSAP makes it easy to create next-generation effects today. [Note: the animation below is NOT a video - it's regular DOM elements being animated with GSAP. And yes, the scrubber works!] 3D transforms textShadow boxShadow borderRadius clip JS -moz- -o- -webkit- -ms- -no-more- play These features work in virtually all modern-day browsers (see caniuse.com for details about browser support for each feature). Generally if the browser supports the css property (browser-prefixed or not), you can animate it with GSAP's CSSPlugin. In fact, GSAP even works around several browser bugs and glitches to deliver a whole new level of consistency to your animations. It can't work miracles or, for example, permit fancy 3D transforms in IE8, but it does a bunch of work under the hood to empower these features as consistently as possible. 3D Transforms Browser support: GOOD (Chrome 12, Safari 4, Firefox 10, IE 10, iOS 3.2, Android 3.0) see details GSAP makes it a breeze to create amazing 3D effects. In addition to all the standard 2D transform properties like rotation, scaleX, scaleY, x, and y, you can also tween 3D properties like rotationX, rotationY, rotationZ, z, perspective and transformPerspective. You can even create multiple tweens that animate each property independently in a staggered fashion and/or with different eases (something virtually impossible to do with CSS3 transitions). In order to get the most out of these 3D properties, it's important to understand how perspective and transformPerspective work. They both affect the amount of distortion applied in 3D space. transformPerspective affects only the element that is being animated, making it look as though it has its own distinct vanishing point in its own 3D space. You can choose to give each element a transformPerspective specifically or use CSSPlugin.defaultTransformPerspective to set a default that will be used for all animated elements that don't have one specifically defined. transformPerspective no transformPerspective No visual distortion at all. Impossible to distinguish vanishing point or depth. DOM elements by default have no transformPerspective. transformPerspective:200 The lower the transformPerspective, the more extreme the distortion. transformPerspective:600 With a higher value the 3D effect is less pronounced. play perspective should be applied to the parent of the element(s) being animated - an element's perspective affects all of its children, allowing them to share a common vanishing point. Typically this is the best way to apply realistic perspective to multiple elements (instead of using transformPerspective on each child element). Practically speaking, you'd almost never use BOTH transformPerspective AND perspective. transformPerspective Vs perspective transformPerspective is applied to each box causing each box to have its own vanishing point A single perspective is applied to the parent div of all the boxes causing each box to share the same vanishing point play transformOrigin can add some really interesting effects - think of it like a pivot point around which your transforms happen. By default, it is in the center of the element ("50% 50%"). transformOrigin is a space-delimited string of values in the following order [x-axis y-axis z-axis] (the z-axis value is optional). You can define the values using the keywords "top", "left", "right", or "bottom" or use percentages (bottom right corner would be "100% 100%") or pixels. transformOrigin The negative z-index (-200) set in the transformOrigin properties of the second animation changes the effect drastically. TweenMax.to(box1, 3, {rotationY:360, transformOrigin:"left top"}) TweenMax.to(box2, 3, {rotationY:360, transformOrigin:"left 50% -200"}) play Caveats: Performance can vary greatly between the browsers. Generally Webkit browsers like Chrome and Safari do best by far, and Firefox lags behind but updates are getting pushed out pretty aggressively by everyone so things can change fast. In some browsers, you may notice a slight shift of pixels when an element starts/ends a 3D animation. This has nothing to do with GSAP - it's the browser jumping into 3D mode and working with the GPU. The only known workaround is to make sure you apply some sort of 3D transform from the beginning which you could do in your css like "transform:translateZ(0.1px);" (plus the obligatory vendor-prefixed variations). Font antialiasing can appear to change when there's a 3D element on screen. Again, this is a browser issue and has nothing to do with GSAP. In Webkit browsers, you can [mostly] resolve this by setting -webkit-font-smoothing:antialiased in your css. If a browser doesn't support 3D transforms, they will simply be ignored (no errors are generated). In some versions of Firefox, elements with BOTH a boxShadow AND 3D transforms applied don't always render correctly (again, it's a browser issue). We're not aware of a workaround but we expect Firefox to fix the bug in a future release.

Any part of an element that would render outside the clipping region will be invisible. This includes the content of the element and its children, backgrounds, borders, outlines, and even any visible scrolling mechanism. You define the rectangle as "rect()" containing a comma-delimited list of four values — top, right, bottom, and left—in that order. Negative length values are allowed. The top and bottom positions are relative to the top border edge of the element’s box. The left and right positions are relative to the left border edge in a left-to-right environment, or to the right border edge in a right-to-left environment. TweenMax.to(element, 0.5, { // rect(top, right, bottom, left) clip:"rect(0px,150px,150px,0px)" }); Move your cursor over the images to see a variety of clip effects. TweenMax.from(img1, 1, {clip:"rect(50px 100px 50px 0px)"}) TweenMax.from(img2, 2, {clip:"rect(100px 0px 100px 0px)"}) TweenMax.from(img3, 2, {clip:"rect(50px 50px 50px 50px)"}) TweenMax.from(img4, 2, {clip:"rect(0px 100px 100px 100px)"}) When doing a from() tween (as demonstrated above) that uses the css clip property the target of the tween must have a clip property applied prior to the tween running. View a simple example or the full demo code. Note: although the sample code on this page uses TweenMax, CSSPlugin works equally well with TweenLite. Just don't forget to load CSSPlugin with TweenLite (it's already included inside TweenMax's js file for convenience). Conclusion There has never been a better time for animation in the browser. Before now, developers had to wrestle with clunky css transitions or css animations which can't accommodate even moderately complex sequences with fine-tuned control over individual properties or deliver solid control over entire sequences, plus they couldn't work around some of the browser bugs (like Safari's major transformOrigin inconsistency or Firefox's randomly disappearing 3D transforms) and they required a bunch of prefixes and redundant code. JavaScript options were very limited as well and none (that we could find) solved some key issues. With GSAP, you can finally get the control and consistency you need and it delivers solid performance as well (much better than jQuery - see the "cage match" for a detailed comparison). Make sure you download a fresh copy of the GSAP JavaScript files from the main GSAP JS page and go have some fun (if you're a Club GreenSock member, you can download it with your bonus plugins from your GreenSock account).

  13. The GreenSock Animation Platform (GSAP) animates anything JavaScript can touch (CSS properties, SVG, React, canvas, generic objects, whatever) and solves countless browser inconsistencies, all with blazing speed (up to 20x faster than jQuery). See "Why GSAP?" to learn why it's used by over 8,000,000 sites and every major brand. Hang in there through the learning curve and you'll discover how addictive animating with code can be. We promise it's worth your time. Quick links Loading GSAP Tweening Basics CSSPlugin 2D and 3D transforms Easing Callbacks Sequencing with Timelines Timeline control Getter / Setter methods Club GreenSock We'll cover the most popular features here but keep the GSAP docs handy for all the details. First, let's talk about what GSAP actually does... GSAP as a property manipulator Animation ultimately boils down to changing property values many times per second, making something appear to move, fade, spin, etc. GSAP snags a starting value, an ending value and then interpolates between them 60 times per second. For example, changing the x coordinate of an object from 0 to 1000 over the course of 1 second makes it move quickly to the right. Gradually changing opacity from 1 to 0 makes an element fade out. Your job as an animator is to decide which properties to change, how quickly, and the motion's "style" (known as easing - we'll get to that later). To be technically accurate we could have named GSAP the "GreenSock Property Manipulator" (GSPM) but that doesn't have the same ring. DOM, SVG, <canvas>, and beyond GSAP doesn't have a pre-defined list of properties it can handle. It's super flexible, adjusting to almost anything you throw at it. GSAP can animate all of the following: CSS: 2D and 3D transforms, colors, width, opacity, border-radius, margin, and almost every CSS value (with the help of CSSPlugin). SVG attributes: viewBox, width, height, fill, stroke, cx, r, opacity, etc. Plugins like MorphSVG and DrawSVG can be used for advanced effects. Any numeric value For example, an object that gets rendered to an HTML5 <canvas>. Animate the camera position in a 3D scene or filter values. GSAP is often used with Three.js and Pixi.js. Once you learn the basic syntax you'll be able to use GSAP anywhere JavaScript runs. This guide will focus on the most popular use case: animating CSS properties of DOM elements. (Note: if you're using React, read this too.) If you're using any of the following frameworks, these articles may help: React Vue Angular What's GSAP Exactly? GSAP is a suite of tools for scripted animation. It includes: TweenLite - the lightweight core of the engine which animates any property of any object. It can be expanded using optional plugins. TweenMax - the most feature-packed (and popular) tool in the arsenal. For convenience and loading efficiency, it includes TweenLite, TimelineLite, TimelineMax, CSSPlugin, AttrPlugin, RoundPropsPlugin, BezierPlugin, and EasePack (all in one file). TimelineLite & TimelineMax - sequencing tools that act as containers for tweens, making it simple to control entire groups and precisely manage relative timing (more on this later).

We'll use CodePen demos so that you can easily fork and edit each example right in your browser. TweenMax.to() To create an animation, TweenMax.to() needs 3 things: target - the object you are animating. This can be a raw object, an array of objects, or selector text like ".myClass". duration (in seconds) vars - an object with property/value pairs that you're animating to (like opacity:0.5, rotation:45, etc.) and other optional special properties like onComplete. For example, to move an element with an id of "logo" to an x position of 100 (same as transform: translateX(100px)) over the course of 1 second: TweenMax.to("#logo", 1, {x:100}); Note: Remember that GSAP isn't just for DOM elements, so you could even animate custom properties of a raw object like this: var obj = {prop:10}; TweenMax.to(obj, 1, { prop:200, //onUpdate fires each time the tween updates; we'll explain callbacks later. onUpdate:function() { console.log(obj.prop); //logs the value on each update. } }); Demo: TweenMax.to() Basic Usage See the Pen TweenMax.to() Basic Usage by GreenSock (@GreenSock) on CodePen. If you would like to edit the code and experiment with your own properties and values, just hit the Edit on CodePen button. Notice that the opacity, scale, rotation and x values are all being animated in the demo above but DOM elements don't actually have those properties! In other words, there's no such thing as element.scale or element.opacity. How'd that work then? It's the magic of CSSPlugin. Before we talk about that, let's explain how plugins work in general. Plugins Think of plugins like special properties that get dynamically added to GSAP in order to inject extra abilities. This keeps the core engine small and efficient, yet allows for unlimited expansion. Each plugin is associated with a specific property name. Among the most popular plugins are: CSSPlugin*: animates CSS values AttrPlugin*: animates attributes of DOM nodes including SVG BezierPlugin*: animates along a curved Bezier path MorphSVGPlugin: smooth morphing of complex SVG paths DrawSVGPlugin: animates the length and position of SVG strokes *loaded with TweenMax CSSPlugin In the previous example, CSSPlugin automatically noticed that the target is a DOM element, so it intercepted the values and did some extra work behind the scenes, applying them as inline styles (element.style.transform and element.style.opacity in that case). Be sure to watch the "Getting Started" video at the top of this article to see it in action. CSSPlugin Features: normalizes behavior across browsers and works around various browser bugs and inconsistencies optimizes performance by auto-layerizing, caching transform components, preventing layout thrashing, etc. controls 2D and 3D transform components (x, y, rotation, scaleX, scaleY, skewX, etc.) independently (eliminating order-of-operation woes) reads computed values so you don't have to manually define starting values animates complex values like borderRadius:"50% 50%" and boxShadow:"0px 0px 20px 20px red" applies vendor-specific prefixes (-moz-, -ms-, -webkit-, etc.) when necessary animates CSS Variables handles color interpolation (rgb, rgba, hsl, hsla, hex) normalizes behavior between SVG and DOM elements (particularly useful with transforms) ...and lots more Basically, CSSPlugin saves you a ton of headaches. Because animating CSS properties is so common, GSAP automatically senses when the target is a DOM element and adds a css:{} wrapper. So internally, for example, {x:100, opacity:0.5, onComplete:myFunc} becomes {css:{x:100, opacity:0.5}, onComplete:myFunc}. That way, CSS-related values get routed to the plugin properly and you don't have to do any extra typing. You're welcome. ? To understand the advanced capabilities of the CSSPlugin read the full CSSPlugin documentation. 2D and 3D transforms CSSPlugin recognizes a number of short codes for transform-related properties: GSAP CSS x: 100 transform: translateX(100px) y: 100 transform: translateY(100px) rotation: 360 transform: rotate(360deg) rotationX: 360 transform: rotateX(360deg) rotationY: 360 transform: rotateY(360deg) skewX: 45 transform: skewX(45deg) skewY: 45 transform: skewY(45deg) scale: 2 transform: scale(2, 2) scaleX: 2 transform: scaleX(2) scaleY: 2 transform: scaleY(2) xPercent: 50 transform: translateX(50%) yPercent: 50 transform: translateY(50%) GSAP can animate any "transform" value but we strongly recommend using the shortcuts above because they're faster and more accurate (GSAP can skip parsing computed matrix values which are inherently ambiguous for rotational values beyond 180 degrees). The other major convenience GSAP affords is independent control of each component while delivering a consistent order-of-operation. Performance note: it's much easier for browsers to update x and y (transforms) rather than top and left which affect document flow. So to move something, we recommend animating x and y. Demo: Multiple 2D and 3D transforms See the Pen Multiple 2D and 3D Transforms by GreenSock (@GreenSock) on CodePen. Additional CSSPlugin notes Be sure to camelCase all hyphenated properties. font-size should be fontSize, background-color should be backgroundColor. When animating positional properties such as left and top, its imperative that the elements you are trying to move also have a css position value of absolute, relative or fixed. vw/vh units aren't currently supported natively, but it's pretty easy to mimic using some JS like x: window.innerWidth * (50 / 100) where 50 is the vw. Just ask in the forums for some help. from() tweens Sometimes it's amazingly convenient to set up your elements where they should end up (after an intro animation, for example) and then animate from other values. That's exactly what TweenMax.from() is for. For example, perhaps your "#logo" element currently has its natural x position at 0 and you create the following tween: TweenMax.from("#logo", 1, {x:100}); The #logo will immediately jump to an x of 100 and animate to an x of 0 (or whatever it was when the tween started). In other words, it's animating FROM the values you provide to whatever they currently are. Demo: TweenMax.from() with multiple properties See the Pen TweenMax.from() tween by GreenSock (@GreenSock) on CodePen. There is also a fromTo() method that allows you to define the starting values and the ending values: //tweens from width 0 to 100 and height 0 to 200 TweenMax.fromTo("#logo", 1.5, {width:0, height:0}, {width:100, height:200}); Special properties (like onComplete) A special property is like a reserved keyword that GSAP handles differently than a normal (animated) property. Special properties are used to define callbacks, delays, easing and more. A basic example of a special property is delay: TweenMax.to("#logo", 1, {x:100, delay:3}); This animation will have a 3-second delay before starting. Other common special properties are: onComplete - a callback that should be triggered when the animation finishes. onUpdate - a callback that should be triggered every time the animation updates/renders ease - the ease that should be used (like Power2.easeInOut) Easing If your animation had a voice, what would it sound like? Should it look playful? Robotic? Slick? Realistic? To become an animation rock star, you must develop a keen sense of easing because it determines the style of movement between point A and point B. The video below illustrates the basics. An "ease" controls the rate of change during a tween. Below is an interactive tool that allows you to visually explore various eases. Note: you can click on the underlined parts of the code at the bottom to change things.

    Nine Flipcards

    Hey there master-tweeners, So for an online portfolio I'm creating I wanted to add a container with ''things I'm good at''. I wanted to make it out of 9 flipcards with an image or logo on the front, and a small text on the back. Onclick they're supposed to flip around and stay that way untill clicked again. Now so far I've come across two methods to achieve this, but both come with some complications. The first method On first glance it looks like it does exactly what I want. The animation is smooth and steady. The problem though is when you click on the (first) card twice in a row, the second animation starts halfway through the first animation disaligning the starting position. (Bad explanation, try it yourself in the codepen lol) The second method This is much less Tweening which is nice because I have to do it for nine cards, but there's something I want, but cant get with this method. I really like the way the cards bounce with the bounce ease when they flip. Since this method uses a reverse, the bounce reverses too which looks weird, obviously. Just get to the point already I guess my questions are the following, - Is there a way to fix the problem in the first method? - Is there a way to fix the problem in the second method? - Most importantly, what method do you guys recommend? - What's the most efficient way to get this to work on nine cards, without copy-pasting the whole thing nine times? Thanks in advance 🙂 Codepens used in the process (the one on the bottom is mine): https://codepen.io/rhernando/pen/vjGxH https://codepen.io/chrisgannon/pen/JtljL
  17. I'm working on a project using ReactJS with Pixi & GSAP and the js library I'm using is called "react-pixi-fiber". I'm trying to reference the React Pixi Sprite object and handling the animation it using GSAP. However, it changes position without easing, and there's no error message showing. Code as below The "moveEle" function will be called from the parent component. class MainObject extends Component { constructor(props) { super(props); this.state = { ... }; this._refEle = React.createRef(); moveEle = options => { TweenLite.to(this._refEle, options.duration, { x: options.x, y: options.y, ease:Power2.easeOut }).play(); }; render() { return ( <Fragment key="MainElesFragment"> <Sprite ref={div => (this._refEle = div)} anchor={centerAnchor} texture={textureUrl} width={width} height={height} x={x} y={y} key="thisEle" /> </Fragment> ) } }
  18. I have divided my home page into 4 divs with the class of ".div-pics". And my goal is everytime you hover on one of them a description appears /with the class of ".div-desc". The animation happens through Greensock TimelineLite and the initial position of the description divs is "top: 100%". The code I currently have works, but not with the desired effect. Right now once you hover any of the divs (.div-pics), all description divs (.div-desc) will appear. Instead I would like only the hovered div's description to come on screen, but I don't know how to target it. ! I have divided my home page into 4 divs with the class of ".div-pics".

  19. Hello! I'm trying to apply an animation to the same element in different time lines. But it works in jumps - without a smooth transition between the states of the element. I have a task to do animation with many elements inside one screen. I have several scenes that need to be run by scrolling or clicking on the menu. Under the link all works approximately, as it is necessary to me. One problem is that the animation does not go smoothly from the first state to the second state and then to the third. https://codepen.io/yuliarushay/pen/PBjeyN Thanks!
  20. Im quite new to GSAP and currently working on a project. I found this slider here online: https://codepen.io/gvrban/pen/qjbpaa and modifyed it to fit my needs. You can find a it on codepen: https://codepen.io/anon/pen/KEYRBY (its ripped out of my project and anonymized so don't wonder for the look) Only problem is, if I resize the page, the slider is of and I have to do a reload of the page to get it fitting again. I understand that it is cause of the calculated variables (which are off after a resize). Is there an easy way to make it responsive or do I have to recalculate it with a window.resize? Thanks in advance.
  21. I've prepared animations for two objects in js, how should i set up the TimeLine so that it executes flipCards() function after let's say 2 seconds from window load? Additionaly it would be nice if I could adjust delays between animations of each object.
  22. Hello folks, For a school project I am creating an analog clock and animating it using GSAP. For now, I've got it moving in the way I want, but part of the functionality of a clock is that it actually shows the current time. So my hence my question, how do I get the arms to show the current hours, minutes and seconds?

    JQuery clock to GSAP

    So for a school product I really want to recreate something like this, but the example here is using jQuery. One of the conditions of the challenge was to use the GSAP libraries, so jQuery is not allowed. Is there an easy way to make this kind of clock using GSAP? Is there fast way to replace jQuery with GSAP withing my js files? I'm a beginner so all the tips are welcome!
  24. Hi all, Not sure if i'm missing something or if I'm doing something incorrect. But I'm trying to run simple unit tests with Jest and Enzyme on my component that uses gsap for a search input box. The component works perfectly fine, animation is great too. But whenever i run my tests, and specifically this line component.find('#close').'click' i get ERROR CANNOT TWEEN A NULL TARGET the close button calls this function below: animation.hideSearch(this.searchInput) animation.hideSearch is: hideSearch(target){ return TweenMax .to(target, duration, { opacity: 0, display: 'none' }) }, And finally here is my search input: <input id='search-input' className={styles.input} value={this.state.searchValue} onChange={this.handleSearch} ref={div => this.searchInput = div}/> Is there anything i need to configure in order to get jest to ignore the gsap animation? Any help is appreciated. thanks!
  25. I've recently got lucky with an answer from PointC in another thread, and now having spent a few hours researching without luck on another matter, I guess I'll try my luck again. The problem: I have 30 points, each with a X and Y value (DIV's with a Top and Left setting), placed around a map of 1536x1080px. A user can select any of these points, and when that happens, a line should be drawn (animated in) from one point, to the selected one. This seems really straight forward, and to some extend I have managed to do that, with canvas drawing (p5.js), but it turns out extremely unsharp, and seems to be way to complicated, for what it should do, I've even tried just creating a DIV, and animating on it's width, thereby faking a line. I'm assuming maybe the GSAP SVG animation tools can solve this, but had no luck finding it, it's all about pre made SVG files from illustrator, which then are masked in animations, I can't do that, seeing as I have too many points, and never know how many new ones will be created. Any good solutions to this? It seems to simple, to be this complicated :S / Chris
