CSS Containment: Spec Implementation and Blink Engine Architecture

These sources provide a technical deep dive into CSS containment, explaining how it functions both as a web standard and within the Blink rendering engine. By treating specific subtrees as independent units, containment allows browsers to optimize style, layout, and paint processes by limiting the scope of changes. The text clarifies that containment is more than a performance hint; it dictates observable behaviors such as clipping, the creation of stacking contexts, and the anchoring of positioned elements. It further details how Blink implements these rules through internal bitsets, eligibility checks for different layout objects, and the use of property trees to isolate rendering tasks. Ultimately, the documentation illustrates how containment serves as a foundational requirement for modern features like container queries and content-visibility.
