Tailwind CSS
A design system of utility classes, not hundreds of lines of custom CSS to maintain.
What it is
Tailwind is a utility-first CSS framework - instead of writing custom classes for every component, a page is composed from small, reusable utilities directly in the markup.
Why we use it
Design tokens (colors, spacing, typography) live in one place and can be enforced - you cannot accidentally use a color outside the palette because no other color exists in the system. The resulting CSS bundle is smaller than with hand-written styles because unused utilities are removed during the build.
Proof, not claims
This website: a complete design system through Tailwind v4 `@theme` variables - one set of tokens for the entire website.
