   Frontend developers who want to style web interfaces directly in their markup and keep design decisions close to the code.

   • Build-time generation: Generates CSS for classes detected in your source files.

   Tailwind CSS Integrations

   Tailwind CSS supports official Vite and PostCSS plugins, with setup guides for Laravel, SvelteKit, React Router, Nuxt, SolidJS, Next.js, and Angular. It also offers a CLI installation path for other build environments.

   Pros and Cons

   Pros:

   • Production CSS includes only detected utility classes
   • Responsive and state variants stay beside markup
   • Custom layouts avoid preset component styling

   Cons:

   • No prebuilt components for quick page assembly
   • Long utility lists clutter component markup
