Without a minimal demo, it's very difficult to troubleshoot; the issue could be caused by CSS, markup, a third party library, a 3rd party script, etc. Would you please provide a very simple CodePen or Stackblitz that illustrates the issue?

Please don't include your whole project. Just some colored <div> elements and the GSAP code is best. See if you can recreate the issue with as few dependencies as possible. Start minimal and then incrementally add code bit by bit until it breaks. Usually people solve their own issues during this process! If not, at least we have a reduced test case which greatly increases your chances of getting a relevant answer.

Yes, it would be super helpful if you provided a very clear minimal demo illustrating the issue.

From a quick glance, my guess is that it's a logic thing related to the fact that the scroll position has a limited resolution. For example, imagine if labelToScroll() returns 500.4567. Well, the browser will only allow you to scroll to whole pixel values. So it'd make perfect sense if your animation doesn't go exactly to the spot you were expecting (but close). See what I mean?

@mickf413 it sounds like you might be right about it being best to write different animations since they're so different (each having a ScrollTrigger in one scenario, but all combined in another), but it's tough to say for sure without seeing a minimal demo. If you still need some help, please make sure you provide a CodePen or Stackbiltz that clearly illustrates the challenge and we'd be happy to take a peek.

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 - we just want to manage expectations.

If you're looking for ScrollTrigger effects, I'd recommend looking at the demos at 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.

We'd love to help, but vague details like 'it's broken' or 'it doesn't work' are very difficult for people to help with. Here are some tips that will increase your chances of getting a relevant 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 minimal demo - if possible, using no frameworks, with minimal styling, only include the code that's absolutely necessary to show the issue. Please don't include your whole project. Just some colored <div> elements is great.

Would you mind clarifying your question please and making sure that you include a minimal demo that illustrates the problem so that we can help you?

Hi @devanshdsoni and welcome to the GSAP Forums!

Proper cleanup is very important with frameworks, but especially with React. React 18 runs in strict mode locally by default which causes your useEffect() and useLayoutEffect() to get called TWICE.

Since GSAP 3.12, we have the useGSAP() hook (the NPM package is here) that simplifies creating and cleaning up animations in React (including Next, Remix, etc). It's a drop-in replacement for useEffect()/useLayoutEffect(). All the GSAP-related objects (animations, ScrollTriggers, etc.) created while the function executes get collected and then reverted when the hook gets torn down.

Here is how it works:

const container = useRef(); // the root level element of your component (for scoping selector text which is optional)

useGSAP(() => {
  // gsap code here...
}, { dependencies: [endX], scope: container }); // config object offers maximum flexibility

Or if you prefer, you can use the same method signature as useEffect():

useGSAP(() => {
  // gsap code here...
}, [endX]); // simple dependency Array setup like useEffect()

This pattern follows React's best practices.

We strongly recommend reading the React guide we've put together at https://gsap.com/resources/React/

If you still need help, here's a React starter template that you can fork to create a minimal demo illustrating whatever issue you're running into. Post a link to your fork back here and we'd be happy to take a peek and answer any GSAP-related questions you have. Just use simple colored <div> elements in your demo; no need to recreate your whole project with client artwork, etc. The simpler the better.

Hi there! I see you're using React -
