Using the ScrollTimeline API for scroll-linked animations

Scroll-linked animations, which are controlled by an element's scroll position, can be implemented using either CSS properties or the Web Animations API, with the ScrollTimeline feature offering a more interactive way to animate elements based on scroll position rather than elapsed time. This technique allows animations to progress forward as users scroll down and reverse when they scroll up, creating dynamic visual effects like animated progress bars that track reading progress on a page. While the ScrollTimeline feature is not yet fully compatible across all browsers, a polyfill can extend its functionality to browsers like Firefox and Safari. Both CSS and the Web Animations API can achieve similar outcomes, with the choice between them largely depending on personal preference for declarative syntax versus JavaScript code. Debugging these animations can be facilitated using the Chrome DevTools extension, which provides detailed insights into the state of scroll-linked animations, aiding in identifying and resolving issues.
