Not able to pin section on Scroll

[Don Jose Mathew]

What i need is i want to pin the red section until scrolling inside the blue section. But it is not working properly getting blinking effect.

Using next js

  useEffect(() => {
    gsap.registerPlugin(ScrollTrigger);

    ScrollTrigger.create({
      trigger: '.sect',
      start: 'top top',

      // pinType: 'fixed',
      pin: true,
      // preventOverlaps: true,
      endTrigger: '.section4',
      markers: true
    });
  });

 

 

JSX Code

<div className="relative bg-[#0093e8b8]">

        <Object3d /> #red color section

        <div className="h-screen  section2"></div>

        <div className="h-screen  section3"></div>

        <div className="h-screen  section4"></div>

      </div>

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 dependancies 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.

 

See the Pen aYYOdN by GreenSock (@GreenSock) on CodePen

that loads all the plugins. Just click "fork" at the bottom right and make your minimal demo: 

 

Using a framework/library like React, Vue, Next, etc.? 

CodePen isn't always ideal for these tools, so here are some Stackblitz starter templates that you can fork and import the gsap-trial NPM package for using any of the bonus plugins: 

• React (please read this article!)
• Next
• Svelte
• Sveltekit
• Vue
• Nuxt

 

Please share the StackBlitz link directly to the file in question (where you've put the GSAP code) so we don't need to hunt through all the files. 

 

Once we see an isolated demo, we'll do our best to jump in and help with your GSAP-specific questions. ✅

By the way, it looks like you're not doing proper cleanup in React. See this article:

I'd recommend just switching from useEffect() to the useGSAP() hook which should make it a lot easier. 

 

If you're still having trouble, please make sure you include a minimal demo that clearly illustrates the issue and we'd be happy to take a peek.
