CSS Scroll Snap: Chromium Implementation and Specification

This documentation provides a comprehensive analysis of CSS Scroll Snap, specifically focusing on its technical implementation within Chromium’s Blink engine. It details how Level 1 specifications allow developers to create controlled, paginated scrolling by defining snap positions and alignment without custom scripts. The text explains the internal architecture, describing how the main thread and compositor thread collaborate to ensure smooth, high-performance animations across various input methods like touch and keyboard. It also addresses complex interoperability issues and edge cases, such as oversized elements and interactions with sticky positioning. Furthermore, the sources outline future Level 2 enhancements, including new JavaScript events and pseudo-classes designed to give authors more stylistic control over the active scroll state. Finally, the material emphasizes accessibility and UX best practices, warning that mandatory snapping can sometimes hinder usability if not tested thoroughly.
