Tailwind CSS v4.0 Alpha is a major update that introduces a faster engine, streamlined configuration, and new features. Built with Rust and Lightning CSS, the new engine significantly improves performance and reduces bundle size. Configuration now happens directly in CSS files using CSS variables, eliminating the need for separate JavaScript config files. Tailwind CSS v4 also comes with built-in support for PostCSS features like @import and nesting, making CSS preprocessing easier.
