Side-by-side snippets (old hack → modern CSS) with difficulty, browser-compat scores and a playground make this an instant lookup for refactors. The curation is pragmatic — examples like translate-centering → place-items, scrollbar-gutter, and OKLCH color swaps show you exactly what to replace and why. I’d love inline live sandboxes and per-browser caveats for tricky edge cases, but the site already shaves hours off common CSS archaeology.
