ScrollSmoother breaks ScrollTrigger?

[DW92]

Hi,

 

I have a problem while using ScrollSmoother and ScrollTrigger together. My animations that depends on ScrollTrigger are broken - part of the animation fires without any transition. E.g. I have an animated text, where I animate it letter, by letter, via Timeline. The problem is - first or even second letter sometimes appear immediately, without any duration.

Is that a known bug or something that happens only to me?

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.

The same happens here. If I uncomment ScrollSmoother the ScrollTrigger stops working.

Any suggestions anyone?

That's actually more of a CSS issue - ScrollSmoother bases things on the height of the content <div>, but the way you set things up in your CSS, the height of that element is actually 0! Check it out in Dev Tools. It's probably because you're using a lot of float: left stuff. I don't have time right now to dig into the reasons for the height being 0, but that's the fundamental problem here. If you simply adjust your CSS/layout so that the content <div> properly reflects the height of the stuff inside of it, that should resolve everything.

Thx, I'm going to try that. Let you know!

I fixed it with your help, thx!
