Sticky text animation

Hi Guys!
I’m trying to make a text animation that will animate when the text is in the center of the screen. After the animation is done you will scroll futher down the page.
I want it to work lika this last section on this page -

I found this in “made in webflow” and trying to adjust it, but I have to little knowledge about css to make it work. It seems like the animation stop working when I remove the “80vh” on the “page” class.

Does anyone know what I should do to make it work?
