Explains how the DOM and CSSOM are built, how the render tree is constructed with computed styles, and how layout, paint, and composite stages work. Highlights performance pitfalls like forced synchronous layout, unnecessary reflows, and excessive layer promotion. Also covers the accessibility tree, stacking contexts and z-index behavior, and how different rendering engines (Blink, WebKit, Gecko) all follow the same fundamental pipeline. ## Full article daily.dev links to this article rather than hosting it.
