What problem does it solve? Building consistent, themeable UI components in Tailwind CSS often leads to scattered utility classes, hardcoded colors, and missing accessibility states. This Skill provides structured patterns for design tokens, component variants, and dark mode so teams can standardize UI across a codebase. ## Core Features & Use Cases - Design Token Architecture: Set up semantic color tokens with CSS variables and HSL values, supporting light and dark themes through a single configuration. - Component Patterns: Implement CVA-based variant components (Button, Card, Input, Grid), compound components, and form components with error states and ARIA attributes. - Theming & Animation: Configure dark mode with a ThemeProvider, and apply enter/exit animations using tailwindcss-animate utilities. - Use Case: When scaffolding a new Next.js app, use this Skill to generate a complete ui/ component library with Button, Card, Input, and Dialog components that share semantic tokens and support dark mode out of the box. ## Quick Start Ask the AI to create a themed Button component with CVA variants and dark mode support using Tailwind CSS.
