Tailwind CSS v4 is not “just another update”. It’s Tailwind finally admitting that CSS won.

Configs are no longer the center of the universe. Tokens live in CSS, layers are real, and the framework stops fighting the browser and starts working with it.

In this talk, I’ll break down how theme, preflight, and utilities actually work in Tailwind v4, and why defining things like --color-* and --spacing-* is a better idea than maintaining giant config files.

The real win? Design tokens.

When your Tailwind theme comes directly from Figma variables, styling stops being guesswork and becomes a contract between designers and developers. Same names, same values, no translation layer, no drama.

This is a short talk about using Tailwind v4 the way it was meant to be used as CSS with superpowers, not magic classes.
