Tailwind v4 moves configuration from a JavaScript file into CSS itself, with a faster engine underneath. It feels less like a separate layer and more like modern CSS with superpowers.
Closer to the platform
CSS-first means leaning on variables, the cascade and modern features the browser already understands. Builds get faster and the distance between your config and the output shrinks.
Our take
We like tooling that gets thinner as the platform gets stronger. This direction fits that — less ceremony, more standards.
