Tailwind CSS v4 brings significant improvements that make styling even more powerful and efficient.

What’s New in v4

Lightning Fast Engine

The new Oxide engine compiles your CSS up to 10x faster than previous versions, making development even smoother.

Simplified Configuration

No more tailwind.config.js for basic setups. Configure everything directly in your CSS file using the new @theme directive.

@import "tailwindcss";

@theme {
  --color-brand: #3b82f6;
  --font-display: "Inter", sans-serif;
}

Better Defaults

Improved color palette, better spacing scale, and more intuitive naming conventions make Tailwind v4 the best version yet.

Migration

Most projects can migrate with minimal changes. The Tailwind team has provided comprehensive migration guides and automated tools.
