## What it is
Skeleton is an adaptive design system built on Tailwind CSS, providing themes, design tokens, utility classes, and turnkey UI components for Svelte and React (powered by Zag.js). It is framework-agnostic at its core, requiring only Tailwind CSS, and includes a CLI for migrations and tooling.

## Use cases
- build a themed component library with tailwind css
- set up a design system for a sveltekit or react app
- accessible ui components for svelte and react
- create and switch multiple themes with css custom properties
- add dark mode to a tailwind project
- style a nextjs or astro app with a consistent design language

## When to choose
- you use Tailwind CSS and want an opinionated, accessible design system with ready-made components
- you work in Svelte or React and want components that adapt to your theme automatically
- you need multi-theme support and dark mode with minimal setup

## When to avoid
- your project uses Flowbite or Daisy UI, which conflict with Skeleton's Tailwind overrides
- you want a fully unstyled headless library with no design opinions
- you don't use Tailwind CSS at all
