GSAP Helper's Achievements

  1. We love helping with GSAP-related questions, but unfortunately we just don't have the resources to provide free general consulting, logic troubleshooting, or "how do I recreate this cool effect I saw on another site?" tutorials. Of course anyone else is welcome to post an answer if they'd like - we just want to manage expectations. If you're looking for ScrollTrigger effects, I'd recommend looking at the demos at https://greensock.com/st-demos and https://codepen.io/collection/DkvGzg and https://codepen.io/collection/AEbkkJ - you may be able to use one of those as a jumping-off point. You are welcome to post in the "Jobs & Freelance" forum for paid consulting, or contact us directly. Otherwise, if you've got a GSAP-specific question just post that here along with a minimal demo and we'd be happy to take a look.
  2. It's pretty tough to troubleshoot without a minimal demo - the issue could be caused by CSS, markup, a third party library, your browser, an external script that's totally unrelated to GSAP, etc. Would you please provide a very simple CodePen or CodeSandbox that demonstrates the issue? Please don't include your whole project. Just some colored <div> elements and the GSAP code is best (avoid frameworks if possible). See if you can recreate the issue with as few dependancies as possible. If not, incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, then at least we have a reduced test case which greatly increases your chances of getting a relevant answer. Here's a starter CodePen that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo: https://codepen.io/GreenSock/pen/aYYOdN If you're using something like React/Next/Vue/Nuxt or some other framework, you may find StackBlitz easier to use. We have a series of collections with different templates for you to get started on these different frameworks: React/Next/Vue/Nuxt. Once we see an isolated demo, we'll do our best to jump in and help with your GSAP-specific questions.

  5. Howdy @DevC! I don't have a lot of time right now to dig into everything here, but I wanted to offer you some quick advice about how to get the most out of these forums... Keep it simple. Don't list a bunch of requirements ("it should animate over each section, and gradient colors over those children, force animation on hero load and then have ScrollTrigger take over dynamically...and I think my code is a mess so please help clean it up" - that's too hard to follow). Just pick the very first thing and see if you can make that work. If you get stuck, post one question focused on that one piece, like "how can I pin each section one at a time?" Keep your CodePen focused only on that one piece with as little code/markup as possible. Then once that's answered, move on to your next question/problem. Baby steps 😉 Before you know it, things will fall into place one at a time. Again, try not to list out all the problems. Break them apart. You'll get a lot more people willing to help you if you keep things simple and clear. A well-crafted minimal demo is GOLD around here - you'll get people falling over themselves to help you if you make a CodePen that's super clear and isolates the issue. Explain exactly how to reproduce the problem, like "scroll down to the blue section and notice how it pins before it hits the top of the viewport" for example. Don't worry - this community has got your back when it comes to GSAP-specific questions. I just wanted to provide some pointers on how to help us help you.
  6. Perhaps the problem is that React 18 runs in "strict" mode locally by default which causes your useEffect() to get called TWICE! Very annoying. It has caused a lot of headaches for a lot of people outside the GSAP community too. .from() tweens use the CURRENT value as the destination and it renders immediately the value you set in the tween, so when it's called the first time it'd work great but if you call it twice, it ends up animating from the from value (no animation). It's not a GSAP bug - it's a logic thing. For example, let's say el.x is 0 and you do this: useEffect(() => { // what happens if this gets called twice? gsap.from(el, {x: 100}) }, []); The first time makes el.x jump immediately to 100 and start animating backwards toward the current value which is 0 (so 100 --> 0). But the second time, it would jump to 100 (same) and animate back to the current value which is now 100 (100 --> 100)! See the issue? In GSAP 3.11, we introduced a new gsap.context() feature that solves all of this for you. All you need to do is wrap your code in a context call, and then return a cleanup function that reverts things: // typically it's best to useLayoutEffect() instead of useEffect() to have React render the initial state properly from the very start. useLayoutEffect(() => { let ctx = gsap.context(() => { // all your GSAP animation code here }); return () => ctx.revert(); // <- cleanup! }, []); One of the React team members chimed in here if you'd like more background. We strongly recommend reading the React article at https://greensock.com/react Happy tweening!

  10. Hey @Claire. I don't have a lot of time right now to dig into everything here, but I wanted to offer you some quick advice about how to get the most out of these forums.... Keep it simple. Don't list a bunch of requirements ("it should start in the middle, then fan out, then have a spotlight, then an SVG appears, then it scales, pinned until finished..." - that's way too hard to follow). Just pick the very first thing and see if you can make that work. If you get stuck, only post a question focused on that one thing, like "how do I trigger the pinning when the SVG is in the center of the viewport?" Keep your CodePen focused only on that one piece. Then once that's answered, move on to your next question. Baby steps Again, don't list out all your problems (the list of requirements that you're having trouble with). You'll get a lot more people willing to help you if you show a willingness to keep things simple and clear for them. And definitely keep your questions focused on GSAP-specific things (like the API) rather than general logic stuff (if possible). Good luck with your project. 👍
  11. I'm a little fuzzy on what you're asking here... Some tips that will increase your chance of getting a solid answer: A clear description of the expected result - "I am expecting the purple div to spin 360degrees" A clear description of the issue - "the purple div only spins 90deg" A list of steps for someone else to recreate the issue - "Open the demo on mobile in IOS safari and scroll down to the grey container" A very clear minimal demo that illustrates the issue By the way, it's generally a very bad idea to do lazy loading in ways that will cause layout shift. I'd recommend setting a width/height on the elements that are loading dynamically so that there's no layout shift.

  13. That sounds like a 'flash of unstyled content' maybe?

  15. We love helping with GSAP-related questions, but unfortunately we just don't have the resources to provide free general consulting or logic troubleshooting. One problem for sure in your demo is that you're using NESTED ScrollTriggers which is a common mistake. It is logically impossible for a timeline's playhead to be controlled by both a parent timeline and the scrollbar position. See Furthermore, if I understand your question correctly, you'd need to cook up some custom logic to calculate exactly when each element is centered in the viewport horizontally. I'm sure it's possible, but it's beyond the scope of help we can provide for free here.
