Mastering Tailwind CSS v4: What's New and How to Use It
Tailwind CSS v4 brings a new engine, CSS-first configuration, and powerful new features. Learn how to upgrade and make the most of it.
Mastering Tailwind CSS v4
Tailwind CSS v4 represents a complete rewrite of the popular utility-first CSS framework. With a new engine, CSS-first configuration, and powerful new features, it's easier than ever to build beautiful, responsive interfaces.
What's New in v4
CSS-First Configuration
Gone are the days of tailwind.config.js. Now you can customize everything directly in CSS using @theme directives.
New Engine
The new engine is built on top of Lightning CSS, offering faster build times and better output quality.
Container Queries
Native container query support makes it easy to create truly responsive components that adapt to their container rather than the viewport.
Getting Started
@import "tailwindcss";
@theme {
--color-primary: oklch(0.54 0.24 263);
--font-sans: "Inter", sans-serif;
}
Conclusion
Tailwind CSS v4 is a significant improvement over v3, with a more intuitive configuration system, better performance, and exciting new features like container queries.
