Incredible scroll-based animations with CSS-only
Channel: Kevin Powell
Date: 2023-12-21

Been playing with them a little bit up until now, and it's finally time time for a deep dive into scroll-timeline and the scroll() and view() value functions.

In this one I look at a few different effects, like a scroll watcher, fading in images as they enter the viewport, moving elements horizontally as we scroll down, and a few more things as we explore everything we can do with scroll-timeline, and I also get into the Polyfill and some of it's limitations as well.
