What about CSS? Progressive Enhancement and CSS
summary
Explains why CSS needs progressive enhancement and gives concrete tactics: start with sensible semantic HTML, layer styles using the cascade, use mobile‑first media queries and flexbox as an enhancement, or serve a tiny legacy stylesheet (BBC “cutting the mustard”). Demonstrates @supports with an object-fit: cover example and the four browser cases (only Internet Explorer lacks @supports), advises putting fallbacks before supports blocks, and recommends real‑device/browser testing rather than emulation.
