Hi @Stasicus welcome to the forum! Check out this awesome tutorial by our own @Carl better than this I can't explain how it works. Hope it helps and happy tweening!

If you want to overlap each little group of elements, I'd go with a child timeline for each group and add those to a parent. The parent then plays/reverses on click. Something like this. https://codepen.io/PointC/pen/jORKGax The overlap is on line 47. Each child timeline is 0.45 seconds in duration so I overlapped by 0.2 seconds (approximately half way), but set everything to your liking. The nice thing with a parent timeline is you can set a timeScale too if everything is too fast or slow for your needs. Happy tweening.

Don't pin just the header pin the whole block and move the content inside. Same as the Stackblitz demo. Again everything in GSAP is an animation. Also always make sure you're loading the latest versions of the plugins, your demo loaded version 3.4.0 we're currently at 3.12.5! https://codepen.io/mvaneijgen/pen/MWRXJgM?editors=0010

sure - just use the start/end properties motionPath: { align: sparklePath, path: sparklePath, alignOrigin: [0.5, -0.5], start: 1, end: 0 }, Happy tweening.

Looks like they just use a curved path in the SVG and scale the y from 0 → 1 on scroll. This should get you started. https://codepen.io/PointC/pen/abxYroe Happy tweening.

I've just build something similar, check it out! Hope it helps and happy tweening! https://codepen.io/mvaneijgen/pen/WNWxPGV?editors=0010

Indeed without a minimal demo seeing the code in action it is hard to help you debug. That said have you seen my post on how to animate all types of different clip masks? Hope it helps and happy tweening! https://codepen.io/mvaneijgen/pen/jOdJGQq

Welcome to the forum. I'd probably use a yoyo and repeat:1 for the opacity in/out. Also making sure the ease is set to none as this is a scrub:true situation. https://codepen.io/PointC/pen/dyLwoej Hopefully that helps. Happy tweening and welcome aboard.

Welcome to the forum. If I understand you correctly, I think you'd want to tween the drawSVG path from 0% 10% → 90% 100%. That way you're always showing 10%. You could also add a tween at the beginning or end to make it appear/disappear too. Happy tweening and welcome aboard. https://codepen.io/PointC/pen/vYMQXWe

Hi @maoux welcome to the forum! Your in luck, it is even easier now. Check out useGSAP()!

This is mostly a structure question and hasn't really to do with GSAP. I would abstract out what are toggle and what are expended elements and then expand all the elements that are connected to the toggle. As you see in your example you don't want to expand elements that have them self content that also should expand, so the HTML structure (and CSS) is really important in this case. I've given each element data-toggle and data-expand with their respective key (eg the name on the link). Right now it doesn't close, personally I don't like it when toggles close them selfs and I think it is bad UX. What If I want to compare content one and three? You could could add a data-close and find all the elements that should close if some data-toggle is clicked, but agin this isn't really a GSAP question, but again more JS logic and is beyond the scope of this forum. Still hope it helps and happy tweening! https://codepen.io/mvaneijgen/pen/BaEqJOM?editors=1101

I think something like this is what you're looking for. I’ve placed some comments in your JS to better explain things, please be sure to read through them! https://codepen.io/mvaneijgen/pen/bGJxXXG?editors=0010 For React, if you have set up the useGSAP() hook correctly and your elements have the same classes and CSS everything should just be a drop in replacement from Codepen. Be suer to check out the following if you need some more guidance. If you're stuck we also have Stackblitz starter templates for all the major frameworks. Again hope it helps and happy tweening!

Hey! Just parachuting in here, but maybe we're focusing on the solution you've attempted instead of the problem you're trying to solve? This made me remember something that may be useful? Without using a motion path, another common animation pattern for curved motion is to animate the x and y values with different eases to get a curve. Check out this demo - https://codepen.io/snorkltv/pen/dyoxXaQ This is useful because it's not trying to animate the element through set coordinates, it's more dynamic. There's a start and end and it's the ease that's handling time rather than position to make the path curved I needed to do a curved flip animation a while back and found out that you can separate out x and y and animate them individually with customProps. (undocumented right now because animating the properties in a flip animation is quite a rare need due to it's dynamic/transitionary nature) but if you want a curved path - it allows you to separate out the properties in the flip animation and ease them individually. https://codepen.io/GreenSock/pen/bGjXGeX/cc6a1577ab5d5ea8ab0722dc407a7929?editors=0010 Maybe that will achieve the "scenic taxi route" for you?

Thanks for providing the demo, it made my approach much easier than starting completely from scratch. This is a cool effect and as stated earlier, I'd probably try to use SVG for this 99% of the time. However, I was intrigued about making a more flexible clipPath approach. In the demo below I animate the y value of each bar independently using a stagger. https://codepen.io/snorkltv/pen/rNbrEra?editors=0010 In the onUpdate I glue all the values together into a giant clipPath string. Using this technique you can animate the bars from center, start, or end adjust the stagger's each amount adjust the distribution of start times with an ease (in the stagger object)

Hi there! Thanks for the kind words. Yeah, canvas is usually better for stuff with lots of elements. Pixi is a library that uses canvas so it makes stuff a little easier than using the browser API directly. Your example is pretty simple though so maybe you could just skip pixi and use canvas? Here's a canvas demo that may help https://codepen.io/ninja1pro/pen/abMMOar?editors=1010 And a pixi demo (this is using old GSAP syntax - but it's using pixi to add images so that's helpful) https://codepen.io/Koenie/pen/qBEJVeN The pixi docs are good too https://pixijs.com/8.x/guides/components/sprites

Hi, That's because of the way the Horizontal Loop helper function works, nothing more. The helper function moves a group of items in the direction you tell it to (reversed config option) and when that element reaches the edge of it's parent is move to the opposite side nothing more. Sure enough sounds simple but the logic behind it in order to make it fully responsive and performant is not 😉. https://gsap.com/docs/v3/HelperFunctions/helpers/seamlessLoop With that being said, why are you trying to animate elements in different parents or outside the parent? I fail to see the logic behind it. We have these demos that use the Observer Plugin and ScrollTrigger to change the direction and speed of the loop instance: https://codepen.io/GreenSock/pen/zYaxEKV https://codepen.io/GreenSock/pen/GRwePYw Finally is worth noticing that you have only two elements in your loop, so for obvious reasons there is going to be a jump and empty space when the elements have to be placed at the start again. Is a good idea to have enough elements to use the entire width of the screen ( in large screens of course). Hopefully this clear things up Happy Tweening!

It's not really a bug. It's just a fundamental logic problem in the way you're setting things up. Let me explain... In order for a callback to fire, the playhead must cross that spot on its parent timeline, or land directly on top of it. So it's based on the playhead moving (its new position). The timeline doesn't render for the first time until the next tick (it'd be silly to render right away by default because the playhead hasn't moved anywhere yet, so it'd be a waste of CPU cycles). That's why the very first one didn't fire right away. The timeline's playhead updates on each "tick" which is typically about every 16.67ms but that really depends on the browser and how busy the CPU is, etc. Your timeline is 2 seconds long and has repeat: -1. So let's say it renders almost at the end, at like 1.9857 seconds, and then on the next tick, the totalTime renders at 2.013 which means that it went past the end and wrapped around to the beginning, and 0.013 seconds into the timeline (from the start). In that ONE tick, it'd fire that callback that's at the very end of the timeline AND since it looped back to the beginning and went a little bit past, it ALSO triggers the callback that's sitting at the very start. Great. BUT What if the playhead happens to land EXACTLY at the end of the timeline (2 seconds precisely)? What do you think should happen? Obviously the callback at the end should fire, but should the callback that's sitting at the very START of the timeline also fire? I mean the end of the timeline and the start of the timeline are not the same technically, so it'd be weird if both fired. The playhead can't be at 2 seconds AND at 0 seconds. It wouldn't make a lot of sense to fire the callbacks from BOTH places on that ONE tick. See the problem? There are many ways to accomplish what I think you're trying to do there (alter visibility of things in a synchronized way), but I'd need to see what other requirements you have in order to offer the best recommendation. Thanks for the excellent minimal demo, by the way. 👍

As with everything to do with GSAP, build an animation. When wanting to create a scrolling effect you frist have to remove the scrolling part and just focus on the animation you want to happen. If you're new to GSAP check out this awesome getting started guide https://gsap.com/resources/get-started/ A while back I've written a guide how to create a card stacking effect, but the logic you're looking for can also be build with it. Below a demo that has a horizontal animation, it is probably not 100% what you're looking for, but if you give it a go I think you'll be able to get it to do what you want with the resources provided. If you still need help please provide a minimal demo showing what you've tried your self and someone here will be happy to point you in the right direction. Happy tweening! https://codepen.io/mvaneijgen/pen/poYzaJW

We're back up again everyone! Thanks for bearing with us through this outage. 💚 We appreciate you all!

@jdhadwin Hello there. While your demo is not exactly minimal, which makes it kind of hard to see through everything, on a quick glimpse I noticed, that you are trying to animate svg elements that are in <g> groups from a scale of 0, which I think is at least part of your problem - and I don't think this specifically is GSAP related. I stumbled upon this a few days ago, too - happening for me in all Chromium based browsers on Windows 11. It appears to be a bug in the chromium browser base that was already reported in September 2022 by @Cassie and later marked as solved from what I can tell reading that old bug report - but now it seems to have resurfaced. @Cassie if you find the time, could your maybe re-new that report or something like that? ... I have absolutely no clue how those work, tbh. https://issues.chromium.org/issues/40240236 These following pens don't use GSAP at all - and as you should be able to see, when elements in groups are being 'manipulated' so they start out with a scale of 0 and then changed later on, their values will get changed properly inline on the element - but the element just won't get rendered then (unless you resize the window along the process, e.g., or scroll the SVG fully out of viewport and then back into view again). https://codepen.io/akapowl/pen/vYMWZrL This will not happen with elements that are not in <g> groups, though. https://codepen.io/akapowl/pen/QWPOgzm What helped for me as a workaround was to tween from a very small scale like 0.001 instead of absolute 0. Maybe that can help you out somehow, until that issue gets resolved again. I will add, that this is just something I was able to quickly notice. If it doesn't help in your case, and you suspect that there still might be some issues with GSAP, please create a demo that is boiled down to the bare minimum but still reproduces the issue you're having, so it is easier to identify for others, what could be causing it. https://codepen.io/akapowl/pen/dyLZzyM

You don't need GSAP to add a class to an element, just use .classList.add(yourClass); The problem with that is that it either has the class or it does not, there is no in-between state, so nothing will animate, see below. You're on the GSAP forum, so I think you look to animate things, then just create an animation for each property you want to change, much more fun and easier to control! Hope it helps and happy tweening! https://codepen.io/mvaneijgen/pen/dyLzJxg?editors=0011

GSAP is smart and on page load calculates everything it needs to do the animation, so that when it is time it to animate it doesn't need to do calculations anymore. In your case you have two ScrollTrigger animating the same element, so both of them see the initial state of your gradient and record that and when it is time they animate from that initial state to their new state. You want the second ScrollTrigger to wait until the first one has finished. You could do this multiple ways, but the easiest is to give the second tween immediateRender: false, so that it waits until it needs to do the animation. Hope it helps and happy tweening! https://codepen.io/mvaneijgen/pen/RwOgqJj?editors=0010

That's because the browser's getComputedStyle() doesn't return the calc() data properly. So when GSAP gets the starting (from) value, the browser gives it a value with no calc(), and then the end string has calc() in it with multiple numbers. It's the same issue with your other demos (mis-matched data/quantities). There are two solutions: 1) Use CSS variables: https://codepen.io/GreenSock/pen/RwOgRJQ 2) Use a normal .fromTo() tween so that GSAP understands what you're trying to do and can use the raw starting value instead of a computed one from the browser: https://codepen.io/GreenSock/pen/wvZeWXQ?editors=0110

hi @alexr8 maybe these 2 demos help 1 with draggable and 1 without https://codepen.io/GreenSock/pen/BaQXjWw?editors=0010 https://codepen.io/GreenSock/pen/RwKwLWK

Your video is around 15 seconds long, so I've split it up in three sections of each 5 seconds. First of the best thing to do when working with ScrollTrigger is to remove it! This seems counter intuitive, but ScrollTrigger is just animating something on scroll, so just focus on the animation at first and only when you're happy with the animation add ScrollTrigger back in. This way you can focus on one part at a time and it will save a lot of headache when debugging. I've enabled GSDevTools for the animation, so we can first fully focus on the animation and create what we want to happen on scroll. I've modified your HTML and CSS, I've created a .trigger element and have everything stack right on top of each other with CSS (please disable all the JS to see what it looks like) I've taken this logic from my stacking cards post I encourage you to read through it, see below Then on the timeline I've put all the tweens, frist the video tweens to 5 seconds over a duration of 5 seconds, then the video tweens to 10 seconds over a duration of 5 seconds and at the same time the first card animates in from of screen, and them the same for the next card. This is probably not fully correct, but it shows you how you can create a timeline and have things happen at the same time. I've add some ScrollTrigger code but this is commented out, but you can enable it to see what this would do on scroll, but be sure to disable it again when you want to tweak the animation. If you're new to GSAP check out this awesome getting started guide https://gsap.com/resources/get-started/ and check out this awesome tutorial how to work with ScrollTrigger. Hope it helps and happy tweening! https://codepen.io/mvaneijgen/pen/bGJOQzq?editors=1010

Although this didn't feel intuitive to me in this scenario, autoScroll did fix the issue. Thanks a lot!

We have several mouse follow effect threads. Here are a couple that should point you in the right direction. Happy tweening.

You'll want to put all the tweens on a timeline and move the scrollTrigger to the timeline rather than the single tween. https://codepen.io/PointC/pen/gOyQWqY Hopefully that helps. Happy tweening.

You can use scrollTo plugin to scroll to certain element, but because you are animating sections, you can't use them as reference. Instead, you need to wrap them in another wrapper so you can use this wrapper in scrollTo. https://codepen.io/SahilAFX/pen/jOReGmM

Hi @Haris Khan welcome to the forum! A timeline is the most powerful tool in GSAP with it you can put tweens in a sequence and thus in this case have ScrollTrigger play your timeline in full. If you're new to GSAP check out this awesome getting started guide https://gsap.com/resources/get-started/ Hope it helps and happy tweening! https://codepen.io/mvaneijgen/pen/bGJxyeV?editors=0010

Hi, this is a very very old thread. The correct way to do this now is using our flip plugin. https://codepen.io/GreenSock/pen/zYqLjre Hope this helps!

Hey, so you can achieve this with another loop within your current loop. https://codepen.io/GreenSock/pen/LYvrxwd?editors=1010 If that's not the correct order, the easiest way to fix that is to change the order of the items within the SVG, but you could also use array methods in JS to swop the order around. If you need to adjust the timing, you should look into the position parameter. Hope this helps!

Thanks Rodrigo, I mistakenly had the autoKill outside of the scrollTo, like this... //DON'T DO THIS// gsap.to(window, { duration: 1, scrollTo: '#anchor' + jumpChapter, autoKill: true }); //DON'T TO THIS//

Hi @Fumiho welcome to the forum! The best thing to do when working with ScrollTrigger is to remove it! This seems counter intuitive, but ScrollTrigger is just animating something on scroll, so just focus on the animation at first and only when you're happy with the animation add ScrollTrigger back in. This way you can focus on one part at a time and it will save a lot of headache when debugging. You have four "hello" blocks and you want them to move off screen, but have the last one stay. Your logic right now is move them all 100% of their width times the number of .project elements, this is what it is doing now, but your logic is they should all do that expect for the last one, so just subtracted one from your calculations. This is why removing ScrollTrigger is such a powerful move, now you can check just the animation if it is doing what you expect it to do and don't have to worry about what is causing your issue. What could be even more powerful when debugging is changing out projects.length for a hard coded value eg just try the hard coded value of "4" and see what that does, then try "3" and see what that does, this always helps me. Getting dynamic values is great for final code, but before you can get there you first have to know what it is you're trying to do and trying hard coded values probably results in you finding your own solutions. A few weeks back I've written the following post with a philosophy that really helps me debug any project I'm working on, give it a read. Hope it helps and happy tweening! https://codepen.io/mvaneijgen/pen/gOyKwqa?editors=0010

Hi @Rodrigo, 🤦‍♂️ Total facepalm moment, thank you for picking up on that! Thanks for the resources also, I've been looking over them and they definitely feel more like home to me. I imagine we'll be mixing both react components and vanilla JS in an upcoming project, so it will be nice to use an animation library that's more framework agnostic than what Framer Motion offers. Going forward I anticipate GSAP becoming a staple in our future projects. Thanks again!

Hi @WakuWakuCodingu welcome to the forum! Looks perfect to me I would not change a thing! Certainly not if this if your first time using the tool. Pin spacing is needed for ScrollTrigger to do its magic, so you can really remove it. You can but then all your further sections will overlap you animation You could use gsap.utils.toArray, but you can also just feed a query selector to the GSAP tween and it will also get all the elements. In this case I've set all your .innerBox elements and add a stagger to the animation so they come in one by one. I've also move the ScrollTrigger logic to the timeline, so now it is even more clear what ScrollTrigger is controlling. Indeed in this case is it not strictly necessary to set overflow: hidden; but it also doesn't harm anything. https://codepen.io/mvaneijgen/pen/bGJvLZz I've written a guide how to create the kinds of card stacking effect, yours works perfectly, but maybe you can get some knowledge from it. Hope it helps and happy tweening!

Not always no, it's dependent on your font loading strategy https://stackoverflow.com/questions/25223470/does-domcontentloaded-wait-for-web-fonts-firefox#:~:text=NO%2C it does NOT!,to make it pixel perfect.&text=inside the head (it's called browser preload hints).

Hi @Boba welcome to the forum! Then you're looking for the Observer plugin https://gsap.com/docs/v3/Plugins/Observer/ below an example from the docs it behaves like you're describing https://codepen.io/GreenSock/pen/XWzRraJ Personally I find that demo hard to understand, so here the same logic but with a timeline and labels, which allow you to manually define to which point each scroll should go with which interaction of the user And here an example that mixes normal scroll with the Observer plugin https://codepen.io/GreenSock/pen/oNQPLqJ Hope it helps and happy tweening!

We're back up again everyone! Thanks for bearing with us through this outage. 💚

Hi there, thanks for the heads up. There's an issue with our SSL cert I'm afraid. I've contacted @Prasanna who handles our private repo and we'll keep this thread updated. In the interim you can use the zip install to access the files. So sorry everyone. Hold tight! https://gsap.com/docs/v3/Installation?tab=npm&module=esm&method=zip&tier=free&club=true&require=false&trial=true

Also using this.https://codepen.io/GreenSock/pen/XWOeLEb

Just did 👍 Edit - For anyone wanting updates on this: Since that is not considered a regression of the fix for the original issue, it got opened as a new issue. https://issues.chromium.org/issues/332328859

Commented on that thread again! 🫠

Hi, The demo I shared in my previous post was a way to show you how to do this a learning resource of sorts, nothing more. We don't have the time resources to provide fully working solutions for our users or give free general consulting in these free forums. We have to keep our focus on solving GSAP related questions and issues. In order to understand how this works I recommend you to check this guide by David DeSandro: https://3dtransforms.desandro.com/carousel Finally if you want to use the Motion Path Plugin you can check any of these threads: Also you can see this video where @Carl goes into a lot of detail about this: Hopefully this helps. Happy Tweening!

Because you are setting ease none on the set tween instead of to tween, so by default it animates with 'Power1.out' ease and slows down at end.

hello, i need support from a gsap expert for two website elements (slider & scrolltriggered sections). the implementation and construction of the html framework should be done in webflow. who has the time and inclination?

For the text I would use SplitText https://gsap.com/docs/v3/Plugins/SplitText/ and then stagger each the letters Keep in mind all ScrollTrigger is doing is animating your animation on scroll, so just build the animation and don't worry about ScrollTrigger at all. I've written a guide how to create card stacking effects and the logic can be applied here 1 on 1, you just have more elements that stack, so before doing anything you first want to lay everything out with CSS. See the post below and a demo from the post that animates a clipPath, which is also part of the animation I would suggest just start building in Codepen and first do all the CSS, then try to animate some things and only when you're done start thinking about ScrollTrigger. Pro tip in between fork your work, so you have versions on which you can fall back. When you get stuck post back here with a demo and one particular question and some one here will be sure to point you in the right direction. Hope it helps and happy tweening! https://codepen.io/mvaneijgen/pen/GReQYBr

I built a helper function specifically for this: https://codepen.io/GreenSock/pen/vYMJdjB?editors=0010 Related forums post: I hope that helps!

Hi, On top of @mvaneijgen's great solution you could also use the onToggle callback from ScrollTrigger: onToggle Function - A callback for when the ScrollTrigger toggles from inactive to active or the other way around. This is typically when the scroll position moves past the "start" or "end" in either direction, but if it shoots past BOTH on the same tick, like if the user scrolls extremely fast, onToggle won't fire because the state hasn't changed. You can often use this one callback in the place of onEnter, onLeave, onEnterBack, and onLeaveBack by just checking the isActive property for toggling things. Here is a simple fork of your demo: https://codepen.io/GreenSock/pen/XWQaZdV Hopefully this helps. Happy Tweening!

Here's a simple code example of invalidateOnRefresh gsap.to(".el", { xPercent: () => window.innerWidth / 2, // here's a functional value that will update if the window size changes, (it will 'invalidate' on 'refresh') rotation: window.innerWidth / 2, // this value won't update scrollTrigger: { invalidateOnRefresh: true ... } })
