Tailwind CSS v4: Core Features and Migration Guide

2026-06-29 • 1 min read

Tailwind CSS v4 introduces a new compilation engine written in Rust, boosting build speeds up to ten times.

Configuration changes from a JavaScript config file to pure CSS directives, simplifying project configuration.

Container queries are now built into utility classes, letting you style components based on parent sizes instead of viewport width.

Migrate projects by upgrading dependencies and changing tailwind.config.js properties into CSS custom properties.

Utilizing native container classes ensures cleaner component structure and faster stylesheet delivery in production.
