SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Tailwind CSS v4 patterns and guidelines help frontend teams design, implement, and maintain consistent UI components by clarifying when to use pure utilities versus abstractions (CVA, Tailwind Variants) and how to configure a CSS-first design system.

Core Features & Use Cases

  • Clear rules for when to use pure utilities, CVA, or Tailwind Variants based on the number of variants.
  • Guidance for a CSS-first setup using @theme and CSS variables to standardize design tokens.
  • Practical patterns for building component libraries with React and Tailwind v4, including migration tips and accessibility considerations.

Quick Start

Begin by adopting a CSS-first setup and applying the 3+ variant rule when creating components.

FAQPage Schema
How do I configure a CSS-first design system in Tailwind v4?▼

Configure a CSS-first design system in Tailwind v4 using the @theme directive and CSS variables to standardize design tokens directly in your stylesheet. This approach replaces JavaScript configuration files for styling.

When should I use CVA or Tailwind Variants instead of pure utility classes?▼

Apply the 3+ variant rule: use pure utility classes for simple components, but choose CVA or Tailwind Variants when a React component requires three or more variants to maintain scalable and consistent patterns.

What is the best way to migrate a React component library from Tailwind v3 to v4?▼

Migrate a React component library from Tailwind v3 to v4 by adopting a CSS-first setup with @theme, mapping your existing design tokens to CSS variables, and refactoring component patterns to align with v4 guidelines.

Does Tailwind v4 work with React component libraries using CVA?▼

Yes, Tailwind v4 works seamlessly with React component libraries using CVA, providing clear rules for abstraction and standardizing design tokens to ensure consistent UI component patterns across frontend teams.

How do I maintain accessibility when building Tailwind v4 components?▼

Maintain accessibility in Tailwind v4 components by applying practical React patterns that standardize design tokens and variant strategies, ensuring consistent UI behavior and semantic structure across the component library.
