CSS Grid, Flexbox & Container Queries

This page collects 7 articles, newest first. Layout, mostly. When Grid beats Flexbox and when reaching for Grid is overkill, how container queries change component design once you stop thinking in page-level breakpoints, and the newer primitives like anchor positioning that finally kill a whole class of JavaScript positioning hacks. Subgrid gets its own guide because the browser support story changed and most tutorials still reflect the old one. Scroll-driven animations too, with the caveat that they need a `prefers-reduced-motion` guard before they go anywhere near production. The examples are the kind you can paste into a component, not isolated demos that only work inside their own codepen. Centering gets a full guide, unapologetically, because people still ask.
