    A GSAP tale: One goofy guy’s odyssey from knowing nothing to knowing just enough to confuse himself. (This is crazy long so feel free to jump to the epic conclusion). Greetings fellow GreenSockers. The end of this week marks the one-year anniversary of my first post on the forum so I thought I’d take the opportunity to share my 12-month story and hopefully encourage others to jump into the conversations around here. Maybe you’ll recognize yourself in some of the things I’ve experienced. My quick history in a nutshell Web design and coding is a second career for me. After 15 years of owning and operating a photography studio and processing lab (back in the film days - yup - I’m old), the digital camera came along and changed that industry, which necessitated a new career for me. I shifted to video production, which led to motion graphics and finally to web design. Our little agency now offers all those services. The web design clients never needed anything fancy so JavaScript took a back seat to HTML & CSS only sites for a number of years. JavaScript & GSAP: false starts and other obligations I first discovered GSAP a few years ago, but only tried it briefly. It looked cool, but with the time obligations of field video work and motion graphics jobs, it wasn’t something I could work into the schedule. Besides that, it was JavaScript – too complicated I thought. I knew JavaScript was the third piece of a good web designer’s skillset along with HTML and CSS, but I always convinced myself that I didn’t have the time and the sites we built didn’t need it. JavaScript Books + Classes = Fail I did make a few attempts at reading some JavaScript books and working through some online tutorials, but it just never ‘stuck’. Maybe the examples were too theoretical and dry or they were the wrong books and classes. I really don’t know, but I abandoned the learning process a number of times. Cut and Paste mentality Why did I really need to learn anyway? You can just Google what you need, cut and paste some code and presto – you’ve got some working JavaScript or jQuery. I only understood a small portion of what I was cutting and pasting, but hey… it worked so the problem was solved. That’s how I operated for quite some time. What’s a loop? What’s an array? What’s an object? Who cares? Wait a minute. This is ridiculous. Last spring, I was remodeling our company website and I had all these grand visions about making things move and behave in certain ways. Googling for code just wasn’t cutting it. I suddenly felt stupid. “This is ridiculous!” I thought. I should be able to learn how to write my own code. Oh yeah, I remembered that GreenSock thing I had looked at a few times and abandoned. That might work. Maybe I could actually learn how to use it this time. I become a forum lurker I started lurking in the shadows of the forum. After reading a lot of posts, I saw people asking many types of questions from simple to crazy complicated (at least to me). Two things I noticed were that every effort was made to find an answer (no matter the difficulty level of the question) and not one post was condescending or snarky. That’s quite rare on the ol’ interwebs, isn’t it? Hmmmm…maybe I’m in the right place. Oh boy… time to ask a question of my own One of the great things about learning GSAP is you’ll also pick up a lot of other JavaScript and/or jQuery along the way. I kept reading and practicing with some simple tweens, but now I had a question. Dare I post? I suppose, like many others, I feared looking like an idiot even though the forum members and moderators seemed quite nice and helpful. I do several dumb things every day so you’d think I’d be used to it by now. Oh well, here goes. My first question had to do with the indexOf() a Draggable snap array. Within 30 minutes, Diaco and Rodrigo had posted great answers and neither one called me stupid! Yay – how cool. I get hooked on GSAP and the forum About that same time, I decided our company should discontinue on-site video production and switch to studio only filming. I got tired of lugging loads of video gear in and out of buildings – it’s quite tiring and as I mentioned earlier – I’m old. This freed up some time and I decided to dedicate that time to learning GSAP and maybe, one day, even helping others. It wasn’t too long and I actually knew the answer to a forum question. I posted some information and wow – a little red indicator lit up on my control panel. Someone liked something I wrote. How fun – I’m hooked. Carl makes direct contact I continued to learn and experiment. I posted a few additional questions of my own, but I tried to answer more than I asked. If someone posted a question for which I had no answer, I tried to look it up in the docs and figure it out. Most of the time I was far too slow and Jack, Carl or one of the mods would already have the answer posted before I was done reading the question, but it was an interesting way to learn. I did sneak in a few good answers, which led to a private message from Carl. He thanked me for participating and helping in the forums. I thought it was pretty cool that a super smart guy like Professor Schooff would take the time to do that for little ol’ me. My decision to dedicate time to the platform and forum was reinforced. Blake and I have a conversation I don’t recall if it was a back and forth in a forum post or a private message conversation, but Blake told me something that, of course is obvious, but it stuck with me and is important for all of us to remember. He mentioned that we all enter this learning process knowing nothing. If someone of Blake’s considerable skill level can be humble enough to remember first starting out in code, there may be hope for me after all. I guess if you think about it, there was a time when the simple concept of a variable was brand new to all of us. We’re not born with these abilities. They’re learned and we’re all at different points on the educational path. Never feel stupid for not knowing something. Moderator Promotion Throughout the last year, I’ve continued to learn and study both GSAP and JavaScript. Some of those books I abandoned in the past even make sense now. I’ve tried to be active in the GS community and answer as many forum questions as possible. If I’ve answered a question of yours, I hope you found it somewhat helpful. I’ve cranked out some fun CodePens and finally started a Twitter account to tweet them out. I am nowhere near an expert with GSAP or JavaScript, but I know so much more than I knew a year ago. Apparently I know enough to be entrusted with a forum promotion to Moderator status. I’m honored to be included on such an amazing team. 12 months down – what’s next? My agency duties are still numerous so I can’t dedicate full time to coding, but it remains something to which I’m committed and thoroughly enjoy. I started this 12-month GSAP journey just wanting the ability to write my own code rather than cutting and pasting the work of others. I’m confident I have achieved that, but I still have days when a simple piece of code just won’t coalesce in my brain and that can be frustrating. I guess we all have those days, right? I make several mistakes every day, but that’s o.k. too. I learn a lot more from my screw-ups than I ever do when it all goes right on the first try. I plan to keep learning and getting better and when I get stuck, I’ll be able to get an answer from this amazing community. I’ll continue to give back to the GS community by answering any questions that are within my abilities to do so. The super mods: Jonathan, Blake, Diaco and Rodrigo Thank you to my fellow moderators. You guys rock and have taught me so much. @Jonathan – if there is a browser bug, quirk or special fix that you are not aware of, I’ve yet to read about it. Your knowledge has helped me fix many pieces of code before they even became a problem. Plus, if I ever have a question of top/left vs. x/y, I know who I’ll ask. @Blake – if I could be half as good at coding as you, I’d be a very happy guy. Your work always teaches and inspires me. I don’t think you’re allowed to ever stop posting on the forum or we may all show up on your doorstep and ask questions. @Diaco – your code is always so concise. I deconstruct some of your pens and am astounded by how much you squeeze out of a few lines. If I made some of your pens from scratch, I’d have 20 variables, 5 loops, 12 tweens and 80 lines of code. You do the same with two variables and 4 lines of code. Amazing stuff. @Rodrigo – when searching the forum, I often land on one of your past posts and learn a lot. Your knowledge is vast and I wish you had more time to post around here. Your ninja skills are incredibly strong. Our superhero leaders @Carl – I’ve participated in several online forums ranging from graphic design to 3D to video production, but the GreenSock forum is the best and a big part of that is you. You not only provide great answers, but you do it in clever ways with just the right amount of humor thrown in here and there. The collection of videos you’ve made is invaluable and should be mandatory viewing for anyone interested in GSAP. I’ve seen you monitoring the forums at all hours of the day and even on weekends. When you get any sleep I’ll never know, but I thank you for your dedication and sharing your knowledge. @Jack – how you had the vision to start GreenSock and write the first version of the animation platform I can only imagine. I’m glad you did because GSAP is such an amazing collection of tools. The friendliness of the community is definitely following your lead. I don’t understand a lot of what you talk about sometimes, but I know enough to be amazed by your brilliance and talent. You call yourself just a guy who geeks out about code, but you’re more than that. You’re a smart and generous innovator who’s created a special brand and place on the web. I think I can safely speak for the community when I say we all appreciate the time and effort you put into helping us make beautiful and high-performance animations. Thank you sir. The epic conclusion. Well… maybe just a regular conclusion. If you didn’t read the whole post, I don’t blame you. It’s ridiculously long and I’m just some guy you don’t know so I’ll wrap it up with this bit of advice. Whether you’re a genius or feel like an idiot, it doesn’t matter. Try to learn one new thing each day and before you know it, a year will have passed and all those little bits will add up to new skills and abilities. If you’ve never posted on the forum, please jump in and participate. The more voices we have around here, the more we all benefit. If you need an answer, please don’t be afraid to ask a question. Believe me, I’m just some goofy guy in front of a computer. If I can learn this stuff, so can you. As I begin my second year in GreenSockLand, I’m looking forward to learning more, seeing everyone’s work and answering as many of your questions as I can. This is an amazing community and I encourage anyone reading this to set up an account and get involved. My best to all of my fellow GreenSockers. See you around the forums. - Craig (PointC) PS I made a little CodePen to commemorate my one-year forum anniversary. It’s how I felt before and after discovering the power of GSAP. Enjoy.

    Hey GreenSockers, This is my 2,000th post so I wanted to take a minute to commemorate the occasion. It’s so much fun to hang out with all of you. As I’ve said before, this is truly a unique place on the web. The community is so friendly and smart and I learn a ton by reading through different approaches to problems and reverse engineering all the clever answers and demos. Thank you all for sharing your knowledge. A special thanks to @GreenSock and @Carl for putting up with me for 2,000 posts. Shout-out to all the other mods @Jonathan, @OSUblake, @Dipscom, @Sahil, @Rodrigo, @Shaun Gorneau, @Acccent, @Visual-Q, @mikel. You are a terrific group of people (and one A.I.) and I’m inspired by all of you. I hope my little SVG tips & tricks have helped some community members save some time and prevent a few headaches. I’m looking forward to continuing this never-ending journey of learning with the entire GreenSock community. Happy tweening. - Craig

    Hi there! My name is Sarah, I'm on the Vue core team and do a lot of work with Vue and SVG animation using GSAP. Yep, you're on the right track, refs are the way to target these elements though technically it still works to target an id or class as usual. However, there are some key pieces in here that I want to separate out in case it's helpful to you, because really the sky's the limit! And they play so well together: 1) The way that animation and rendering work, you are *always* going to be touching the DOM in the case of animation, this can't only happen in the virtual DOM (something that people miss about React, too, even when looking at libraries like React-Motion) 2) There's a way to interpolate numbers that then update the DOM by transitioning state, and then there is accessing the DOM directly. You can use Vue and GSAP for both. I rewrote the docs example to use GSAP for our transitioning state example here: https://vuejs.org/v2/guide/transitioning-state.html#Animating-State-with-Watchers, but the way you're working with the DOM nodes and watchers, you may be more interested in this chart I wrote with where I'm spinning up SVG DOM nodes with directives, which is similar to what you're doing. In other words, you can use Vue and GSAP to interpolate number or values, and then apply that to a style binding, OR you can just update the fill in GSAP by targeting the element directly, that will still work. There is even a relative HSL tween that gsap offers if that's your jam 3) You might also want to set things up with a transition component, which offer some javascript hooks for beforeEnter, enter, and leaving states: (I have a bunch of pens that do this but this is probably the simplest Vue Book Content Typer) The nice thing that the transition component offers you is an ability to coordinate one thing entering and another leaving, with transition modes. They're pretty spectacular. You will also be given FLIP under the hood with the transition-group component. 4) You can also plug directly into the mounted lifecycle hook, as you can see here: Vue Weather Notifier Pen. This way you can activate an SVG animation on the component as soon as it's in the DOM. You can also see in this pen I'm changing opacity, using drawSVG, changing color, rotating, you name it- it's all possible on SVG elements and you don't *have* to put them in data. Though there's nothing wrong with transitioning state that way either. I also wrote this article that should help you: https://css-tricks.com/intro-to-vue-5-animations/ And have this open source repo which is a whole workshop just about vue and svg animations: https://github.com/sdras/animating-vue-workshop Please feel free to ask any questions as well. Thanks!

    I got sliiiightly carried away and made this, haha. I don't if it will help because I saw @Rodrigo and @PointC had provided great answers so I didn't bother commenting the code, but feel free to ask if anything is intriguing. PointC, thanks! hehe

    Hi and welcome to the GreenSock forums!! A looooooooong time ago I made this for another question in the forums. It uses the draggable tool to move the numbers but you could easily use it to get started with what you need: I made a fork of it and changed a bit to simulate what you need: Hopefully this helps. Happy Tweening!!!

    Yep - the animation is usually easy. (especially with GSAP). Most of the work is in asset prep and organization. I did a post over at CodePen about using the pencil to recreate a font for a handwriting effect. It's pretty much the same technique to create a mask except you don't have to be as precise. A mask has to be close and just enough stroke-width to cover the artwork. You may find some of the info useful. https://codepen.io/PointC/post/animated-handwriting-effect-part-1 https://codepen.io/PointC/post/animated-handwriting-effect-part-2 And the pen that goes with it. Happy tweening.

    Nice job @Sahil! A while back I was toying with the idea of releasing a tool that'd make this sort of thing easier but I put it on the backburner for a while. I called it "BendyBox" - it basically lets you convert any DIV or RECT into an object thats bendable in various ways. It swaps in an SVG to create those effects and you can register various animation effects that you easily call later, like "drop", "spin", etc. Advanced demo: Basic (with quasi-documentation in comments): Again, not sure if we'll make it an official GreenSock tool yet, but I figured this is a good place to share about it. Feedback is welcome.

    Hi alessio, Just use transformOrigin. TweenMax.fromTo('.test', 0.6, {scale: 1}, {scale: 1.1, repeat: -1, repeatDelay:0, yoyo: true, transformOrigin: 'center center'});

    That's because when a tween is defined it is rendered immediately to the start position, usually only noticed in the case of 'from tweens'. Because you are using set at the start of timeline, it is behaving same. You can set immediateRender to false on first tween and it will behave as expected. Well and you can use just fromTo tween to same thing. // To tween tl.set(".slide", { opacity: 1, immediateRender: false }); tl.to(".slide", 1, { x: 300, opacity: 0 }); // fromTo tween tl.fromTo(".slide", 1, { opacity: 1, immediateRender: false }, { x: 300, opacity: 0 });

    Hello dear friends, No doubt Christmas is coming ... Hi @Jonathan - sorry, when I saw your new portrait, I just felt the need to redecorate my tree to dedicate it to the GreenSock community. I coded my first Christmas tree inspired by the work of Petr Tichy (here) Dec 2015. It was one of my first exercises. Kind regards Mikel

    Hey fellow GreenSockers, I’ve seen some demos and questions lately with SVGs containing nested groups that are 10 deep and generic class names that aren’t helpful. This makes your job tougher, so I thought I’d share a few tips for better SVG exports from Adobe Illustrator. I’ve created a simple SVG with a background rectangle, some ungrouped squares, a group of circles, a group of lines and one open wavy path. Here’s the artwork with the layer panel in AI. Tip 1: IDs If you have elements that you know you’ll be targeting individually, give them an ID in AI. In this case I’ve given each of the colored squares a name. I’ve also named the wavy open path. Tip 2: Grouping If you have a group of elements that you’ll want to stagger or somehow target as a group, create a group for them. Simply select all of them and pressing Ctrl + G will make a group for you. You can also create a sub-layer and add them to it or create an entirely separate layer. Do whatever works for you. Just get them grouped before export. You can see in my layers panels I have a masterGroup around everything and then nested groups around the straight lines and circles. The elements in those groups do not need an ID as I’ll have no need to target them individually. You can also use nested groups within nested groups. Maybe a character has a group called ‘#face’, but the eyes need to be their own group within the face group. If that’s what you need for control, go for it. Tip 3: Export Settings Choose File –-> Export –-> Export As --> then choose ‘Save as type: SVG’. The directory is unimportant as you won’t actually be saving it. Choose Export at the bottom of that panel and then we’ll get to the important settings. The next screen you’ll see will be for the SVG Options. At this point you could choose OK and the file would be saved, but I find it best to click to ‘Show Code’ instead. That will launch a text editor which will allow you to copy and paste the code into your editor. Make certain the Object IDs is set to Layer Names. If not, the group names and path IDs will not come through to the SVG. The most important setting here is the Styling. If you choose: Internal CSS, you’ll get a bunch of generic class names. The IDs will still come through, but I don’t find generic class names helpful at all. Here’s what you get with that export. <svg xmlns="http://www.w3.org/2000/svg" width="1000" height="500" viewBox="0 0 1000 500"> <defs> <style> .cls-1 { fill: #333; } .cls-2 { fill: #ff0; } .cls-3 { fill: #7ac943; } .cls-4 { fill: #3fa9f5; } .cls-5 { fill: #ff931e; } .cls-6 { fill: none; stroke: #e6e6e6; stroke-miterlimit: 10; stroke-width: 4px; } </style> </defs> <g id="backgroundGroup"> <rect id="backgroundGray" class="cls-1" width="1000" height="500"/> </g> <g id="masterGroup"> <g id="nestedCircles"> <circle class="cls-2" cx="650" cy="150" r="50"/> <circle class="cls-3" cx="650" cy="350" r="50"/> <circle class="cls-4" cx="850" cy="150" r="50"/> <circle class="cls-5" cx="850" cy="350" r="50"/> </g> <rect id="greenBox" class="cls-3" x="100" y="100" width="100" height="100"/> <rect id="blueBox" class="cls-4" x="100" y="300" width="100" height="100"/> <rect id="orangeBox" class="cls-5" x="300" y="100" width="100" height="100"/> <rect id="yellowBox" class="cls-2" x="300" y="300" width="100" height="100"/> <path id="wavyPath" class="cls-6" d="M68,457c45.67-15.25,115.6-33,201-31,84.49,2,104.92,21.37,193,25,108.61,4.48,136.93-22.58,236-28,61.7-3.37,150.91,1.64,262,43"/> <g id="straightLines"> <line class="cls-6" x1="450" y1="100" x2="450" y2="400"/> <line class="cls-6" x1="500" y1="100" x2="500" y2="400"/> <line class="cls-6" x1="550" y1="100" x2="550" y2="400"/> </g> </g> </svg> For styling I prefer to set it to Presentation Attributes. Here’s what you get with that setting. <svg xmlns="http://www.w3.org/2000/svg" width="1000" height="500" viewBox="0 0 1000 500"> <g id="backgroundGroup"> <rect id="backgroundGray" width="1000" height="500" fill="#333"/> </g> <g id="masterGroup"> <g id="nestedCircles"> <circle cx="650" cy="150" r="50" fill="#ff0"/> <circle cx="650" cy="350" r="50" fill="#7ac943"/> <circle cx="850" cy="150" r="50" fill="#3fa9f5"/> <circle cx="850" cy="350" r="50" fill="#ff931e"/> </g> <rect id="greenBox" x="100" y="100" width="100" height="100" fill="#7ac943"/> <rect id="blueBox" x="100" y="300" width="100" height="100" fill="#3fa9f5"/> <rect id="orangeBox" x="300" y="100" width="100" height="100" fill="#ff931e"/> <rect id="yellowBox" x="300" y="300" width="100" height="100" fill="#ff0"/> <path id="wavyPath" d="M68,457c45.67-15.25,115.6-33,201-31,84.49,2,104.92,21.37,193,25,108.61,4.48,136.93-22.58,236-28,61.7-3.37,150.91,1.64,262,43" fill="none" stroke="#e6e6e6" stroke-miterlimit="10" stroke-width="4"/> <g id="straightLines"> <line x1="450" y1="100" x2="450" y2="400" fill="none" stroke="#e6e6e6" stroke-miterlimit="10" stroke-width="4"/> <line x1="500" y1="100" x2="500" y2="400" fill="none" stroke="#e6e6e6" stroke-miterlimit="10" stroke-width="4"/> <line x1="550" y1="100" x2="550" y2="400" fill="none" stroke="#e6e6e6" stroke-miterlimit="10" stroke-width="4"/> </g> </g> </svg> The output is much cleaner and any of those attributes can be easily controlled with CSS or GSAP. This code straight out of AI is ready to animate with no cleanup necessary. You can quickly target those group child elements for whatever you need. It’s the best of both worlds as you can get to each element for a stagger without the need for unique IDs and you can also control them as a collective. The nested circles can be targeted like this: tl.staggerFrom("#nestedCircles circle", 0.5, {attr:{r:0}}, 0.15); Or easily targeted as a group: tl.to("#nestedCircles", 1, {svgOrigin:"750 250", rotation:360}); Bottom line: Better artwork prep will make your GreenSock life easier. Proper names and grouping before you export will make your animation work go faster as you won’t have to fumble with meaningless class names and trying to group things in your code editor. That’s not to say that you can’t tweak a few names or groups – I do that all the time. But the more things you can have exported from AI correctly, the easier your coding and animation work will be. Of course, all this is just my two-cent opinion. Take from it what you will. Hopefully some of it will be helpful. Happy tweening.

    Great examples, guys! Here is another approach from @OSUblake using the ModifiersPlugin which isn't necessarily simple, but it is dynamic. Blake's ModifiersPlugin collection: https://codepen.io/collection/AWxOyk/ more on ModifiersPlugin: https://greensock.com/modifiersPlugin If you're animation is canned, as you say, Shaun's solution should work very well.

    An even easier way to do this is to make the stagger value negative .staggerFrom(".box", .8, {y:60}, -0.15)

    So, last night I was listening to Jack's awesome interview with egghead.io (https://itunes.apple.com/us/podcast/egghead-io-instructor-chats/id1308497805#) and he started talking about all the unexpected uses of GSAP, and it got me thinking; what have I used GSAP for? And I realized the range is from pretty typical to not so typical! My line of work is for a few large clients. So I've used GSAP on many projects; some externally facing (marketing sites) ... some for "exclusive" groups (targeted marketing), and many internally facing (for very specific groups ... members and employees). So, for the typical stuff, it's Immersive content UI indicators and helpers UX sauce For the not so typical, it get's pretty varied pretty quick! But the one project that sticks out the most is GSAP as the heart of a frontend delivery system (backed by Drupal) that drives a community cable channel for a gated resort community in GA. The Drupal side allows content managers to create and place 3 types of media; image slideshows, video, and embedded (iframed) HTML. They have control over timings and transitions which map out to GSAP, background audio playlists and ducking (the ducking is tweened with GSAP ), and asset publish/unpublish dates. For the embedded HTML ... they are calling in external sites which are slideshows, but managed by another group for another purpose; a real estate listings slideshow of active properties within the community that is displayed on a large screen in their sales office which is ... you guessed it ... GSAP! It cycles through 280 properties (+/- a few) daily; transitioning in a property image, then a delayed detail and pricing overlay slides over a portion of the image. But back to the cable channel ... every asset and configuration managed on the Drupal side is fed through custom template files that generate all the GSAP Timelines and Tweens. It has been running for years and is rock solid! So, my not so typical uses are cable channel programming (in the sense of delivering programmed content), digital kiosks, and digital signage. So, I'm curious ... what have others used GSAP for that might be a little outside the norm?! Edit: I changed the title from "What have you done with GreenSock?" to "How have you used GreenSock?" Upon reading it back some time later ... it occured to me that the title could be implying that something is wrong with GreenSock Of course there isn't!

    Hi again @determin1st .. #1 We are helping you... #2 GSAP is already popular and does rule forever This isn't a GSAP algorithm thing . GSAP can only use what CSS property values are reported and computed by the browser, based on how you have your HTML and CSS setup. Like i said above this has to do with the CSS Spec on how height is calculated with box-sizing. As well as how the CSS box-model works. That is the nature of CSS, animating padding will affect height of its parent regardless if box-sizing is used or not Animating anything but transforms and opacity will cause jank (lost frames). Transforms and opacity do not cause a repaint and layout to be recalculated on every render tick frame. Transforms are also better for interface object, since they can animate on a sub-pixel level for silky smooth motion. Whereas padding and other non transform and opacity properties can only animate on a pixel level. And non transform or opacity CSS properties cant take advantage of hardware acceleration (the GPU) for smoother animation. You could take advantage of using transform scale instead of padding. We can only offer advise and solutions, but in the end its up to you. Happy Tweening!

    Here is how you can do it. I have left some comments in the code but most of the math is self explanatory, you can learn these kind of animations using this book: http://lamberta.github.io/html5-animation For better performance you can use opaque canvas.

    What? Aw, that spoiled my day. Come on, @Sahil, we love having you around here! Don't let @PointC intimidate you He's only pretending to be insecure. This place just wouldn't be the same without @PointC, @Sahil, @OSUblake, @Jonathan, @Dipscom, @Carl, @Rodrigo, @mikel, etc. And now we've got some others coming on strong as well, like @Acccent, @Visual-Q, @Shaun Gorneau and more. Love it! Battle for that leader board, guys.

    Sure, GSAP can do everything anime can do plus a lot more. And GSAP is faster too. It looks like the demo you provided leverages some other helper classes pretty heavily, and anime was only used for small portions. Here's a fork where I swapped in GSAP for the anime code: The structure of things seemed a bit convoluted so I may have missed something, but it appears to work just fine with my edits. Is that what you were looking for?

    I think I see what the problem is - GSAP doesn't natively interpolate "vw" or "vh" units (though it likely will when 2.0.0 is released, but that won't be for a few months most likely). It can set() them directly, but interpolating is different. In this case, the inbetween values are converted to px. So here's a solution that gives you the same result but just does the conversion for you at the right time: Is that what you're after?

    Hi @ericshew The most noticeable problem is line 19. //Switch this tl.reversed() ? tl.play() : tl.reversed(); //to this tl.reversed() ? tl.play() : tl.reverse(); That should get everything working for you. It can certainly work with playing and reversing the timelines like that, but you'll see some harsh morph jumps when hovering on/off quickly between <li> tags. You could get some smoother morphs with rapid hovering like this: Just my two cents worth. Hopefully that helps. Happy tweening.

    So what is the edit at the bottom about? What kind of solutions are they looking at, or possibly thinking about? Right now I'm just not seeing a lot of value in WAAPI from an animator's perspective. The performance is nice, but it's not a game changer. And there will be other ways to improve GSAP performance in the future. Have you looked at Houdini? The cornerstone of Houdini is the CSS Typed Object Model. It's CSS with types e.g. number, length, matrix, keyword, color. The current CSS object model is string-based. To animate the DOM, the browser and GSAP have to spend a lot of time parsing, converting, and building string values, which is dumb. A matrix should not be a string. With Typed OM, that process will be mostly eliminated. .box { height: 30%; } // What's the height? console.log(getComputedStyle(box).getPropertyValue("height")); // "259.5px" console.log(getComputedStyleMap(box).get("height")); // CSSUnitValue {value: 30, unit: "percent", type: "percent"} That can provide a HUGE performance boost. I don't remember what talk I heard this from, but somebody benchmarked animating transforms on 1000 elements using rAF. They found that the browser was spending about two-thirds of the frame budget just parsing the transform strings. When benchmarked using Typed OM, the parsing time was virtually eliminated. The goal of Houdini is to make looking at caniuse.com a thing of the past. You will no longer need to wait around for a browser to implement a feature. Just copy and paste the raw code that makes it tick! One part of that raw code might be paint worklets using the Custom CSS Painting API. It allows you to draw stuff directly to an element's background, border, content, mask, etc. Paint worklets run in a separate thread, so it could be used to improve performance. I was looking at how GSAP could be leveraged inside a separate thread, but some changes would need to be made to the library. A worklet has no access to the window or document, and there are no timing mechanisms like requestAnimationFrame or setTimeout. An animation would have to be manually stepped setting something like a time or progress value. And a paint worklet is stateless, so you can't save/store values. You can create instances of stuff, but the painting has to behave almost like a pure function. One reason for that is because the browser can create the same worklet multiple times, and will kill them as it sees fit. Another reason is the same paint worklet can be called multiple times for different properties or different elements. I know that sounds like using GSAP would be pointless, but it could still be leveraged. On the DOM side, GSAP can tween something like a progress or time value, and in the worklet we can take that value, and plug it into a tween or timeline to interpolate values on some objects. We can then use those values to paint stuff on the element. It's works just like a canvas animation. Here's a demo that animates Google's logo. Yeah, I copied most of it, but look at the paint code. It's calling an interpolate function everywhere. That could obviously be replaced with a tween or timeline. Even better, using the MorphSVG plugin with canvas Path2D objects which can draw SVG paths. On the DOM side, I'm using GSAP to tween a simple --scale property, which is what drives the morphing animation. Well, there's also a --total-time property, but that is being updated by a rAF call. It's used to animate the balls up and down when the --scale is at 0. Note that in order to view this demo, you must use Chrome or Opera, and enable the Experimental Web Platform feature. You can always disable it afterwards if having it enabled scares you. You can copy and paste this into your address/search bar to jump directly to the flag. about://flags/#enable-experimental-web-platform-features And once you have that flag set, be sure to check out some of the Houdini demos here. https://lab.iamvdo.me/houdini/ripple Houdini is still evolving, so there's lots of room to make suggestions and get something incorporated into the spec. Getting the WAAPI spec to change will much harder as that's more mature. Houdini does have a draft for an animation worklet, but right now it seems to be geared towards doing scrolling animations with WAAPI. I would much rather have a general purpose JavaScript animation worklet that doesn't depend on WAAPI or DOM elements.

    Hi and welcome to the GreenSock forums, Regardless of what the effect is, the main thing GSAP is going to handle for you is the sequencing of animations. What it boils down to is taking a fullscreen element, introducing a column on the right that is split vertically, and then introducing another column on the right that is split vertically. I would start with trying to do the css layout for the final state: http://prntscr.com/hdrf3p Just try to get a few different colored divs to fill the screen like that. And then use TimelineMax to sequence each element coming in and resizing as necessary. 90% of the challenge is going to be in building the HTML and CSS the right way. I'm guessing the GSAP code is going to literally be 3 or 4 lines for that transition. If you don't know TimelineLite/Max, put this project to the side and experiment with the basics. https://greensock.com/sequence-video https://greensock.com/position-parameter
