    Both previews render the same markup; the HTML tab below is that markup without a framework.

    Install

    React
    npx shadcn@latest add https://www.themes.dev/ui/r/slider.json
    Astro
    npx shadcn@latest add https://www.themes.dev/ui/r/astro/slider.json

    Or copy the files below into your project. They need clsx, tailwind-merge, and the themes.dev UI theme. The HTML needs only the compiled CSS and the script.
