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

Oh yes, that's exactly what i was looking for ... wouldn't have guessed i could morphSVG from a class name to another class name. Best library ever! (I promise to learn to use codepen ... it's just firefox obfuscates referrers and these embeds cause all kind of warnings, so i'm somewhat reluctant, but that's my problem to solve.)

You where almost there! I've move your timeline outside the loop and add the ScrollTrigger logic to the one timeline, then I've add all your tweens to that one timeline and let ScrollTrigger control it. Does that make sense? Hope it helps and happy tweening! https://codepen.io/mvaneijgen/pen/qBwLJXX?editors=1010

Hi, I think the main issue here is the fact that you're using the same element as the scroller (the document element). ScrollTrigger allows you to define a scroller which is the element where ScrollTrigger will look for the scroll position in order to update any Tween/Timeline you pass to it. From the ScrollTrigger docs: scroller String | Element - By default, the scroller is the viewport itself, but if you'd like to add a ScrollTrigger to a scrollable <div>, for example, just define that as the scroller. You can use selector text like "#elementID" or the element itself. https://gsap.com/docs/v3/Plugins/ScrollTrigger/#config-object Here are a couple of demos that use a similar approach: https://codepen.io/GreenSock/pen/yLRQozy https://codepen.io/GreenSock/pen/OJBvBjB Hopefully this helps. Happy Tweening!

Hi @Sikriti Dakua welcome to the forum! What is the part you're having trouble with? In your example you have different coloured sections which each there own text, but in the example you share all the text is all just stacked right on tof of each other. If that is what you want check out my card stacking tutorial of course swap out the cards for just text, but the logic should be the same. With CSS make all the text stack right on top of each other and then just animate them in and out one by one. Also keep in mind 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. Hope it helps and happy tweening, but if you still need help be sure to post back here with what you've tried!

https://codepen.io/GreenSock/pen/MWRPXMr?editors=0011

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

Thanks for the image. That's a great way to try to keep track of the points. Sorry, for any confusion, but in my haste I actually had the "bar3" values duplicated in my clipPath code which is why you were seeing extra points. Thanks for catching that. I removed the extra row of values. As for the from values, you can use those point objects for each bar to come up with a totally custom starting position using a set(). In the demo below I removed the animation to hopefully make it easier to understand how each bar now has a custom y starting value https://codepen.io/snorkltv/pen/qBwMPMw For what it's worth, keeping track of all those points in the clipPath string is pretty tricky for me too, so don't feel bad if it feels like a lot ot take in. As for using svg, the post @mvaneijgen linked to is quite comprehenisve. However, below is a demo from one of my svg lessons if it helps https://codepen.io/snorkltv/pen/rNKVrYx there are now 10 clipping and masking video lessons in SVG Animation with GreenSock if you want to dive deeper.

There you go https://codepen.io/SahilAFX/pen/eYojXbm I have set fixed dimensions for container for demo. When you make it responsive, you will need to change the value by which you divide pos.y. You can use getBBox method of svg to get current height of the path. You will need to tweak animation and calculation for desired effect.

Ha, that is not a good sign! "Keep calm and grap some calming tea", there is probably some server down, if you want to continu working, just grap the CDN files from https://cdn.jsdelivr.net (grap the links via our installer tool) and swap them out in your pen and we're currently looking in to getting the https://unpkg.co packages back in action!

No, that isn't really possible to do a nested default value like that. But perhaps in the next release, I could add a ScrollToPlugin.config({ autoKill: true }) method. I don't think anyone has ever requested something like that before. It wouldn't be terribly expensive kb-wise. I assume you'd both vote for this addition?

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//

The demo you've shared is a way of working with ScrollTrigger, but personally I find it a hard way to wrap my head around what this is doing and how to modify it. What if you want to header to spin before it pins or move the white boxes in one by one from opacity: 0. That is why when starting out treating everything as an animation and worry about the scrolling part later. Yes, but a timeline can have a hundred animations on it. You could create a timeline + ScrollTrigger combo for each section, but if you just want things to happen in sequence you could easily just create one timeline with all the animations on it and one ScrollTrigger that controls that one timeline. I've written a guide how to create a card stacking effect and what is the logic behind it. I think reading this will help you understand how with this way you can easily modify what is happening on scroll and thus make any type of animation you want. Where the demo you've shared is just for that one effect and isn't really easily modified to do anything else. Also below a demo from the collection of that post that shows you with a timeline every 'section' can have it's own effect which is easily possible with this setup, but doesn't mean you need to use it, just to demonstrate. Hope it helps and happy tweening! https://codepen.io/mvaneijgen/pen/abMbwYd

The ScrollTrigger has a direction property that's 1 if the last scroll was forward, and -1 if it was backward. Sorta like: let tl = gsap.timeline({ scrollTrigger: { scrub: true, ... } }); tl.to(...); tl.add(() => { console.log("direction", tl.scrollTrigger.direction); }); Notice I'm using add() for the callback just because it's a little simpler than call() which is only useful if you're passing parameters (uncommon). Is that what you're looking for? If you're not using a ScrollTrigger at all, there's also a helper function for tracking the direction of an animation: https://gsap.com/docs/v3/HelperFunctions/helpers/trackDirection

It does pin as expected but not visible because background image is not set on second section. Instead, after setting bg I see that 2nd section is not unpinning because it is shorter than other sections. Setting end to "+=100%" unpins it correctly. https://codepen.io/SahilAFX/pen/oNOdMQd

Hi @Jumaworks, In fact with the latest update of the Horizontal Loop helper function Jack made, there is no need for convoluted conditional logic blocks like the one you have in your demo: useGSAP( () => { const boxes = gsap.utils.toArray('.box'); gsap.set(boxes, { backgroundColor: gsap.utils.wrap(colors), }); const mm = gsap.matchMedia(); mm.add('(min-width: 769px)', () => { const loop = horizontalLoop(boxes, { repeat: -1, }); }); }, { scope: boxesContainer, } ); Just let MatchMedia and GSAP Context do the reverting work and heavy lifting for you! Simple, easy and clean (like we love our code around here! 😉) Here is a simple demo: https://stackblitz.com/edit/vitejs-vite-wunbqy?file=src%2FApp.jsx&terminal=dev Happy Tweening!

Hi, I think you are overcomplicating this quite a bit. It should be as simple as this: https://codepen.io/GreenSock/pen/zYXWVdw Happy Tweening!

Hi @Brandium welcome to the forum and thanks for being a club member! There is a bit much going on in your demo if you could reduce it to just the mask animation (the part you're having trouble with) it will be much easier for us to help you debug. A note your animation also doesn't work on Desktop Safari (at least not in Version 17.2.1). There are a lot of ways mask animation can work in on the web and a few weeks back I'd written a guide how to use most of them. Maybe your the solution you're looking for is already in there. Take a look an I hope it helps you solve your problem, if not post back here (preferably with a more minimal demo) and someone will be here to point you in the right direction!

@Rodrigo Thanks! That's what I ended up doing. Once you get the hang of going back and forth to the ease visualizer (it would just be impossible without it) you begin to see the relations between the curves and the path movement. It's laborious but interesting! As a reference for anyone trying this approach in a framework with SSR (I'm using Next.JS) always leave your markers on until you are done! I came across a problem with the ScrollTriggers getting moved up when I refreshed the page (because the whole document wasn't ready), and only noticed it far ahead. Had to implement a fix (A ScrollTrigger on the 'body' with a ScrollTrigger.refresh();) and had to start over... I would have noticed the markers being offset if they were on... <<trial and error>> indeed. @GreenSock This helper function is like magic to me! Your initial description says it all <<Helper function that returns an ease that bends time>>! I love it. It's beyond my current coding full grasp, I can kinda read the code, but towards the end get lost in its complexity. None the less it mostly works. I'll definitely use it eventually. Thank you both! As always, the best community I've ever seen.

Commented on that thread again! 🫠

Hi there! Our React docs are a good place to start. There's everything you need to know there in order to port the animation over to react https://gsap.com/resources/React/ If you need specific help, pop back with a demo showing what you've tried.

Also, just a heads up but safari is really struggling recently to paint big changes like this. I tried a few weeks ago and whole sections of the page were chunked out on scroll 🫠 I'd suggest using fixed divs and doing opacity fades instead of targeting background color. https://codepen.io/cassie-codes/pen/YzMVRrr/4a679cfaa6f8a96bd83bceaea0fa01b4?editors=1010

Hi, @akapowl one of the forums superheroes created this nice demo using locomotive that you can check: https://codepen.io/akapowl/pen/wvJroYy Happy Tweening!

Everything just fine and normal in GreenSock tower 😂

Hi @edwardsjethro welcome to the forum! Yes! No it does not. Below from the price page https://gsap.com/pricing/ No you are not, if you want to still sell your theme you'll need to have a business licence. If you stop selling it your current clients will still be able to use the theme they've bought with all the features of the tools. More info over at https://gsap.com/licensing/ Hope it helps and happy tweening!

Your pen doesn't load GSAP nor ScrollTrigger, would be great if you could at least provide a pen that is working at that level. For the centring of things, just remove ScrollTrigger and GSAP and focus on your CSS, lay everything out as you want it. Only after that is done add GSAP back in. for you pin question, pin: true pins everything located inside your trigger element. Your trigger element doesn't contain your circle, so it doesn't get pinned. Instead of using your trigger element as the pin you could also change the pin: true to an element eg pin: ".wrap-all" which would pin everything because this does contain your circle. Hope it helps and happy tweening!

Thanks for the demo. In the future please add new information to new replies. Editing the first post repeatedly makes it difficult for us and others to follow the conversation. I don't know enough about swiper in react to help you with this, particularly how to reference the Swiper inside the onChange callback. However, this bare-bones example shows how to animate the active slide (change it's scale) and animate something inside it (rotate the number div) Hopefully you can find a way to apply something similar to your project https://codepen.io/snorkltv/pen/WNmzezX?editors=0011
