Tailwind CSS
CSS framework built from small single-purpose utility classes
What it is
Tailwind CSS gives you a large set of low-level classes for spacing, color, layout, typography and responsive breakpoints that you compose directly in markup. A build step scans your templates and generates only the CSS you actually use. Front-end developers use it to style custom interfaces without writing separate stylesheets or fighting a prebuilt component theme. It plugs into PostCSS, Vite and a standalone CLI.
