Launching a css-if demo
Launched css-if, a live demo for the CSS if() inline conditional function that landed in Chrome and Edge 137. It walks through six examples — supports(), media(), style(), combined and negated conditions, multiple branches, and a nested if() — all driven by pure CSS radios and :has(), no JavaScript. The page feature-detects support and shows a fallback in browsers that don't have it yet, and deploys to GitHub Pages on merge. Styling builds on css-starter, reusing its picker and callout components.
