What problem does it solve? Styling modern web interfaces consistently across breakpoints, themes, and frameworks requires deep knowledge of Tailwind CSS utilities, and misconfigured builds or missing accessibility patterns cause production bugs that are hard to diagnose. ## Core Features & Use Cases - Responsive Layout Patterns: Mobile-first flexbox, grid, spacing, and typography utilities with breakpoint references from sm through 2xl. - Component Recipes: Ready-to-adapt patterns for cards, navigation bars, forms, modals, and React components with variant props. - Dark Mode & Accessibility: Class- and media-based dark mode toggles, focus management, ARIA patterns, color contrast guidance, and reduced-motion support. - Configuration & Performance: CSS-first v4.1 configuration with @theme, custom utilities, container queries, content-path purging, and production build optimization. - Use Case: When building a product card grid that must adapt from one column on mobile to four on desktop with dark mode support, apply the responsive grid and dark variant patterns directly instead of writing custom CSS. ## Quick Start Ask the assistant to style a React component with Tailwind CSS, for example to build a responsive card grid with dark mode support.
