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:

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.

I have created the demo

Hi,

 

The main issue is here:

.neo {
  width: 100%;
  position: relative;
  div {
    transition: all 0.8s !important;
    margin: 0 auto;
  }
}

Every element inside that is using having a CSS Transition applied to it to every style property that is ever changed, which is exactly what GSAP does. Not only using transition all in your CSS (with !important on top of that) is a bad idea in general, but when you use it with GSAP, is even worst. You should never apply CSS transitions to elements that you're animating with GSAP because when GSAP applies a change, the CSS transition will interrupt that and say "NOPE! I won't allow that to happen yet...I'm gonna drag that change out over the course of my duration..." 

 

Here is a fork of your codepen with that removed:

Hopefully this helps.

Happy Tweening!

thank you that helped a lot.

can the scrolling animation be more lighter?

the element scrolling is happening so fast

Hi,

 

Check this video @Cassie made in order to better understand how that works:

 

Hopefully this helps.
