Mastering CSS Compositing and Blending Mechanisms

This text explores the technical architecture and practical application of CSS compositing and blending, detailing how web browsers combine visual elements with their backgrounds. It distinguishes between blending, which manages color interactions through various mathematical formulas, and compositing, which dictates the final shape and coverage of overlapping pixels. Key properties like mix-blend-mode and background-blend-mode are examined alongside the critical concept of isolation, which prevents unintended blending by creating independent stacking contexts. The documentation also provides a deep look at the Blink rendering engine, explaining how Chrome utilizes GPU shaders and the Skia library to process these complex effects. Furthermore, the sources address performance considerations, security protections for user privacy, and emerging updates in the Level 2 specification. Ultimately, the overview highlights the transition of these features from experimental tools to a stable, interoperable standard across all modern web browsers.
