Blink's ComputedStyle: An In-Depth Analysis

The collection of sources provides a detailed technical analysis of the ComputedStyle object within Blink, the rendering engine for Chromium. The primary source, an in-depth analysis document, explains how ComputedStyle and its generated storage class, BaseComputedStyle, represent the final, resolved CSS values for an element following the RenderingNG pipeline update. The design emphasizes immutability after style resolution, efficient copy-on-write semantics using grouped data fields to save memory, and generated code to handle the numerous CSS properties and comparison logic. These structures are crucial for the rendering process, informing subsequent stages like layout and paint by providing comparison functions (StyleDifference) that determine necessary updates.
