The article introduces the new CSS Animation Timeline API that enables scroll-driven animations natively in browsers without JavaScript. It covers the core concepts, browser support (85% coverage, pending Firefox release), and practical implementation using familiar CSS keyframe syntax. The author provides insights into advanced features and potential pitfalls based on months of hands-on experience.
Background
Traditionally, scroll-based animations on websites required JavaScript libraries, but the new CSS Animation Timeline API brings this capability to native CSS, simplifying development and improving performance. The API builds upon existing CSS animation primitives, making it accessible to developers already familiar with CSS keyframes.
