Tailwind CSS v4 Best Practices

Setup and styling patterns for Tailwind CSS v4 projects.

When to Use

Use this skill when:

• Setting up Tailwind CSS v4 in a project
• Writing component styles with Tailwind utilities
• Deciding when to extract custom CSS vs using utilities
• Avoiding style drift and maintaining consistency

Non-Negotiables (MUST)

• Import Tailwind via a single global CSS entry: @import 'tailwindcss';
• Keep that global CSS imported from the root layout.
• Prefer Tailwind utilities in className for most styling.
• Avoid large custom CSS files; keep custom CSS truly global (resets, tokens).
• Avoid heavy use of arbitrary values unless necessary; prefer consistent tokens.

Class Strategy

• If class strings become hard to read:
  • Extract a small presentational component.
  • Or extract a components/<area>/... wrapper rather than inventing large custom CSS.
