A utility-first CSS framework you style with small classes in your markup instead of writing custom CSS.
Official siteTailwind CSS is a utility-first styling framework. Rather than writing custom CSS files and inventing class names, you compose designs directly in your markup from small single-purpose utility classes (like flex, pt-4, text-center). A build step then scans your files and ships only the utilities you actually used, keeping the final CSS tiny.
The approach is polarising but productive: it keeps styling co-located with markup, enforces a consistent design scale (spacing, colour, type), and removes the naming and dead-CSS problems that plague hand-written stylesheets on large projects.
Tailwind gives you a constrained set of design tokens exposed as utility classes. You build UI by combining them in HTML, configure the design system in one file, and let the build purge everything unused so production CSS stays lean.
Tailwind fits projects that want to move fast with a consistent design system and no growing pile of bespoke CSS — landing pages, product UIs, and design-system components. It pairs especially well with React and Next.js work.
Markup gets verbose — long strings of classes can hurt readability, mitigated with component extraction. There is a learning curve on the class vocabulary, and teams that prefer strict separation of concerns dislike styling in HTML. On this site we use Bootstrap 5, so Tailwind is a tool we apply where it suits, not a house default.

Common questions
Straight answers on how this fits your marketing and build.
No — the opposite. Tailwind scans your files at build time and ships only the utility classes you actually use, so production CSS is typically small. The full utility set only exists during development.
