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 Stackblitz 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:

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

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.

Hi @rocklee and welcome to the GreenSock forums!

When working with Next GSAP plugins must be imported from the dist folder in order to use the UMD modules:

import { ScrollTrigger} from "gsap/dist/ScrollTrigger";

Finally you're not using GSAP context. When working with GSAP on react environments always use GSAP context. Check the resources in this page

If you keep having issues please create a minimal demo on stackblitz in order to see what could be the cause, remember to not include your entire project just a few elements that clearly illustrates the issue.

Happy Tweening!
