CSS Keywords and Blink Rendering Engine

These sources provide a detailed technical history of CSS keywords and features, tracing their evolution from the foundational CSS1 (1996), which introduced the box model and basic typography, through CSS2/2.1, which brought essential features like positioning, z-index, and enhanced selectors. The texts meticulously chronicle the explosion of functionality in the CSS3 modular era, covering crucial layout systems like Flexbox and Grid Layout, as well as visual features such as Transitions, Transforms, and Animations. Crucially, the sources extensively explain how these CSS features are implemented and optimized within Chrome's Blink rendering engine (especially through projects like LayoutNG), focusing on the performance implications for style resolution, layout calculation, and GPU compositing. Finally, they discuss modern additions, including CSS-wide keywords (initial, unset, revert) and maintainability tools like Custom Properties (CSS Variables).
