I’m pretty excited about Scroll-Driven Animations! It’s amazing how we can link @keyframe animations to scroll positions. The API behind it allows for a lot of possibilities, not just tracking how far the page has scrolled. You can tie the animation progress to the scroll position of any element or an element within a scrollable container. These are known as the Scroll Progress timeline and the View Progress timeline. Impressive work!
Bramus Van Damme explains this concept well in his overview article. He has been working on, creating demos, and writing about this for a while, and putting it all on a dedicated website was a smart move.
I also admire Adam’s approach in his introductory article. His design-focused demos resonate with me. Ryan Mulligan’s initial explorations with Polaroid-style images and scrolling effects are also impressive. Bramus’s tools are essential in understanding this technology, given the significant impact of different keywords and values.
Scroll-driven animations are fun and can be seen as progressive enhancement. While currently Chrome-only, they are polyfillable. There’s hope for Safari or Firefox support in the future. The transition to native web technologies like CSS promises better performance and long-term maintainability.
Using CSS for animations is more performant than JavaScript due to the single-threaded nature of DOM interactive JavaScript. Michelle Barker’s in-depth exploration of scroll progress animations showcases the power of CSS in creating smooth animations.
Overflow issues can hinder scroll-driven animations. Using overflow: clip; instead of overflow: hidden can resolve such problems. Kevin Powell covers scenarios where overflow: clip; proves useful.
I’ve been experimenting with Scroll-Driven Animations myself. From highlighting text to zooming in on images based on scroll position, there are endless possibilities. Ryan Mulligan’s approach of triggering different keyframes with custom properties opens up new creative avenues.
Scroll-Driven Animations are still evolving, with innovative ideas emerging. From fitting text to containers to detecting scrollable elements, the potential is vast.
