Skeleton UI Skill

Full Reference: See theming.md for Design Tokens, Custom Themes, Theme Switching, Data Display (Cards, Tables, Avatars), Feedback (Toast, Modal), Navigation (Tabs, Stepper, Pagination), and Stores Setup.

When NOT to Use This Skill

• React/Vue/Angular projects - Skeleton is Svelte-only
• Plain HTML/CSS - Skeleton requires Svelte and Tailwind CSS
• Headless UI needs - Skeleton provides styled components
• SvelteKit not used - Skeleton is optimized for SvelteKit

Installation

# Create new SvelteKit project
npx sv create my-app
cd my-app

# Add Skeleton
npx @skeletonlabs/skeleton-cli add skeleton

# Or manual installation
npm install @skeletonlabs/skeleton @skeletonlabs/tw-plugin
npm install -D tailwindcss postcss autoprefixer

Configuration

tailwind.config.js

import { skeleton } from '@skeletonlabs/tw-plugin';

export default {
  darkMode: 'class',
  content: [
    './src/**/*.{html,js,svelte,ts}',
    require.resolve('@skeletonlabs/skeleton').replace(/\/index\.js$/, '/**/*.{html,js,svelte,ts}')
  ],
  plugins: [
    skeleton({
      themes: {
        preset: ['skeleton', 'modern', 'crimson'],
      },
    }),
  ],
};

Layout Components

AppShell

<script>
  import { AppShell, AppBar, AppRail, AppRailTile } from '@skeletonlabs/skeleton';
  let { children } = $props();

    <AppBar>
      <svelte:fragment slot="lead">
        <strong>My App</strong>
      </svelte:fragment>
      <svelte:fragment slot="trail">

    </AppRail>
  </svelte:fragment>

  {@render children()}

<!-- Token-aware backgrounds -->
<div class="bg-surface-100-800-token">Adapts to theme</div>

Design Tokens

/* Base colors */
--color-primary-500
--color-secondary-500
--color-surface-500

/* Color shades: 50-950 */
--color-primary-50    /* Lightest */
--color-primary-500   /* Base */
--color-primary-950   /* Darkest */

/* Typography */
--base-font-family
--heading-font-family

/* Border radius */
--theme-rounded-base
--theme-rounded-container

Using Design Tokens

<!-- Via Tailwind classes -->
<div class="bg-primary-500 text-on-primary-token">
  Primary background
</div>

<!-- Via CSS variables -->
<div style="background-color: rgb(var(--color-primary-500));">
  Custom styling
</div>

Best Practices

1. Always initialize stores in root layout
2. Use variant classes for consistent styling
3. Leverage design tokens for theme-aware colors
4. Use -token suffix for auto dark/light switching
5. Keep accessibility in mind - use semantic HTML
