SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Styling modern web interfaces consistently is hard: ad-hoc CSS leads to inconsistent spacing, broken responsive behavior, and bloated stylesheets. This Skill provides structured guidance for Tailwind CSS v4, covering CSS-first configuration, design tokens, responsive patterns, and performance optimization. ## Core Features & Use Cases - Tailwind v4 Configuration: Set up CSS-first @theme configuration with custom colors, typography, and spacing tokens instead of legacy tailwind.config.js. - Responsive & Component Patterns: Apply mobile-first breakpoints, responsive grids, and ready-made card, button, input, and flex patterns with dark mode support. - Performance Optimization: Avoid purged dynamic classes, use safelists when needed, and produce minified production builds. - Use Case: When building a landing page, use this Skill to define a brand color palette as CSS variables, compose a responsive card grid, and add a dark mode toggle with class-based strategy. ## Quick Start Ask the agent to build a responsive pricing page with Tailwind CSS v4, including a custom brand theme, dark mode support, and mobile-first grid layout.

Frequently Asked Questions about tailwind_mastery

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I configure Tailwind CSS v4 with a custom theme?▼

Tailwind v4 uses CSS-first configuration: import "tailwindcss" in your CSS file and define tokens inside an @theme block, such as --color-primary, --font-display, and custom spacing values. No tailwind.config.js or content array is required because files are scanned automatically.

How to make a responsive grid layout with Tailwind CSS?▼

Use mobile-first breakpoint prefixes on grid utilities, for example "grid grid-cols-1 md:grid-cols-2 lg:grid-cols-3 gap-4". Base classes apply to mobile, and md, lg, xl, and 2xl prefixes progressively adjust the layout at larger widths.

Does Tailwind CSS v4 support dark mode?▼

Yes, Tailwind supports dark mode via the class strategy: add the "dark" class to the html element and use dark: variants like "bg-white dark:bg-gray-900". You can toggle it with JavaScript and persist the choice in localStorage.

Why are my dynamic Tailwind classes missing in production?▼

Tailwind purges unused classes at build time, so interpolated classes like `text-${color}-500` are not detected and get removed. Always write full class names with conditional logic, or add patterns to the safelist in your config.

Should I use @apply or utility classes for components in Tailwind?▼

The recommended strategy is extracting repeated markup into components rather than using @apply for complex styles. Utility classes stay in the HTML, keeping the purge mechanism effective and the bundle small.
