Please answer the question.


I want the animation to not move up to down. How can I change this way to change the way scroll is triggered not from bottom to top but from top to bottom.



    scrollTrigger: {
      trigger: ".shoe",
      start: 0.5,
      end: 5,
      scrub: false,
      pin: false,
    .from(".midsole",  { y: innerHeight * 0.5 })
    .from(".outsole", { y: innerHeight * 0.5 });

start: 'top top',

end: 'bottom bottom'

Not sure it that'll do it or not, as it's really hard to determine what you are trying to do without a minimal demo:


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

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.

This is my code in CodePen, please check. I attach screenshot for visual presentation. When I scroll this 2 blue panels move down to up. (bottom to top), but I don't know how I can change animation way go to top to bottom (up to down).


(Please open full version Codeopen link, not that embed, because visuals looks not correct)

Hi @edohak and welcome to the GreenSock forums!


I think you're looking for ScrollTrigger's toggleActions:


String - Determines how the linked animation is controlled at the 4 distinct toggle places - onEnter, onLeave, onEnterBack, and onLeaveBack, in that order. The default is play none none none. So toggleActions: "play pause resume reset" will play the animation when entering, pause it when leaving, resume it when entering again backwards, and reset (rewind back to the beginning) when scrolling all the way back past the beginning. You can use any of the following keywords for each action: "play", "pause", "resume", "reset", "restart", "complete", "reverse", and "none".


Here is a fork of your example:

Here is the debug link (no iframes):



Hopefully this helps.

Happy Tweening!
