Tailwind CSS is a utility-first CSS framework: instead of writing custom stylesheets, developers compose interfaces directly in HTML using small utility classes like flex, p-4, and text-center.
A build-time purging system strips every unused class from the final output, so despite shipping thousands of utility classes, production CSS stays remarkably small, avoiding the usual tradeoff between flexibility and file size.
Developers who want to build custom interfaces quickly without maintaining separate CSS files or fighting a rigid component library's existing style choices.
Its config file (tailwind.config.js) is where a project's actual design tokens, colors, spacing, breakpoints, live, worth setting up deliberately from day one rather than relying on the defaults throughout a growing project.
A utility-first CSS framework for fast, flexible UI without pre-made components.
