Skeleton — Adaptive Design System Powered by Tailwind CSS

Introduction

Skeleton is an adaptive design system and component library built on top of Tailwind CSS. It provides pre-built, themeable components for Svelte, React, and other frameworks, combining the utility-first power of Tailwind with a consistent design token system. Skeleton is designed for developers who want Tailwind's flexibility with the productivity of a component library.

What Skeleton Does

• Provides 40+ UI components including app bars, modals, tables, drawers, and toasts
• Integrates directly with Tailwind CSS using a plugin-based architecture
• Supports multiple themes with live theme switching and a visual theme generator
• Offers framework-specific packages for Svelte, React, and SvelteKit
• Includes utility features like light switches, code blocks, and responsive drawers

Architecture Overview

Skeleton extends Tailwind CSS via a custom plugin that registers design tokens as CSS custom properties. Components consume these tokens for consistent theming. The library ships framework-specific packages (@skeletonlabs/skeleton-svelte, @skeletonlabs/skeleton-react) that provide idiomatic components for each framework while sharing the same Tailwind plugin and theme system underneath.

Self-Hosting & Configuration

• Install the core package and your framework-specific adapter
• Add the Skeleton Tailwind plugin to your tailwind.config.js
• Choose a preset theme or create custom themes with the theme generator
• Configure global settings like dark mode toggle and transition preferences
• Works with SvelteKit, Next.js, Vite, and Astro projects

Key Features

• Built-in theme system with CSS custom properties and live theme switching
• Tailwind CSS native with no conflicting style systems
• Visual theme generator for creating branded color palettes
• Components follow each framework's conventions (slots in Svelte, props in React)
• Responsive by default with mobile-first Tailwind utility patterns

FAQ

Q: Does Skeleton work with plain React (not SvelteKit)? A: Yes. Skeleton offers @skeletonlabs/skeleton-react for React and Next.js projects.

Q: Can I use my existing Tailwind configuration? A: Yes. Skeleton adds a Tailwind plugin alongside your existing config. It extends rather than replaces your setup.

Q: How do I switch themes at runtime? A: Apply a data-theme attribute to the html element. Skeleton's tokens update automatically via CSS custom properties.

Q: Is Skeleton suitable for production applications? A: Yes. Skeleton is used in production applications and follows semantic versioning with stable releases.
