When to Use This Skill

Creating a component library with Tailwind v4
Implementing design tokens and theming with CSS-first configuration
Building responsive and accessible components
Standardizing UI patterns across a codebase
Migrating from Tailwind v3 to v4
Setting up dark mode with native CSS features

Key v4 Changes

| v3 Pattern | v4 Pattern |

| ------------------------------------- | --------------------------------------------------------------------- |

| tailwind.config.ts | @theme in CSS |

| @tailwind base/components/utilities | @import "tailwindcss" |

| darkMode: "class" | @custom-variant dark (&:where(.dark, .dark *)) |

| theme.extend.colors | @theme { --color-*: value } |

| require("tailwindcss-animate") | CSS @keyframes in @theme + @starting-style for entry animations |

Quick Start

/* app.css - Tailwind v4 CSS-first configuration */
@import "tailwindcss";

/* Define your theme with @theme */
@theme {
  /* Semantic color tokens using OKLCH for better color perception */
  --color-background: oklch(100% 0 0);

  /* Animation tokens - keyframes inside @theme are output when referenced by --animate-* variables */

/* Base styles */
@layer base {

Core Concepts

1. Design Token Hierarchy

Brand Tokens (abstract)
    └── Semantic Tokens (purpose)
        └── Component Tokens (specific)

Example:
    oklch(45% 0.2 260) → --color-primary → bg-primary

2. Component Architecture

Base styles → Variants → Sizes → States → Overrides

Toolkit for styling artifacts with a theme. These artifacts can be slides, docs, reportings, HTML landing pages, etc. There are 10 pre-set themes with colors/fonts that you can apply to any artifact that has been creating, or can generate a new theme on-the-fly.

Applies Anthropic's official brand colors and typography to any sort of artifact that may benefit from having Anthropic's look-and-feel. Use it when brand colors or style guidelines, visual formatting, or company design standards apply.

Suite of tools for creating elaborate, multi-component claude.ai HTML artifacts using modern frontend web technologies (React, Tailwind CSS, shadcn/ui). Use for complex artifacts requiring state management, routing, or shadcn/ui components - not for simple single-file HTML/JSX artifacts.
