The CSS Animation Timeline API enables scroll-driven animations without JavaScript by mapping keyframe animations to scroll progress instead of time. Using `animation-timeline: view()` or `scroll()`, developers can trigger animations based on an element's position in the viewport. The post covers animation ranges (cover, contain, entry, exit), range percentages for precise control, scroll progress timelines for reading indicators, and linked timelines using `view-timeline` and `timeline-scope` to animate one element based on another element's scroll position.
