Question

Animation

Good afternoon, there is an apple site https://www.apple.com/airpods-pro/ there are very cool effects when scrolling down the site. How would you implement this yourself, it turns out very cool. Are you sure you are using some kind of library? In general, how to do this, where can I read?

Answer 1

There was a discussion on Twitter recently, there are just a lot (very) many images that change each other depending on the scroll position.
