CSS to Tailwind

Guidance for converting legacy CSS to Tailwind v4 class strings while preserving behavior and readability.

Tailwind v4 in this workspace

Theme and shared animation tokens are declared in CSS (@theme, keyed custom properties consumed by utilities). Apps use @import "tailwindcss"; packages/skins layers shared @keyframes / @property / @theme in shared/tailwind.css. When a pattern repeats across components, prefer @utility or @custom-variant in CSS (see site / apps/sandbox styles) rather than proliferating arbitrary values in TS presets.

See references/migration.md for v4-focused rules.

When to use

Migrating stylesheet-based styles to Tailwind utilities
Ensuring packages/skins CSS and tailwind component modules stay visually and behaviorally aligned (parallel css/ and tailwind/ trees)
Auditing Tailwind output for unnecessary arbitrary values or missing theme mappings
