This covers GPUI's layout and styling system, which uses a flexbox and CSS-like approach through helpers like div(), h_flex(), and v_flex(). You'll reach for this when building UI layouts, handling overflow, or positioning elements in a GPUI application. The framework takes a declarative styling approach that should feel familiar if you've done web development, but it's worth noting that GPUI is a lower-level Rust UI framework, so you're trading some convenience for performance and control. The reference includes specifics on flexbox properties, positioning modes, and how styling composes with the rest of GPUI's element system.
