Tailwind CSS v4: The Rust Revolution
Tailwind CSS v4 is a major release that completely rewrites the engine in Rust for maximum performance.

10x Faster Builds

The new Rust-based engine processes your styles 10x faster than the previous JavaScript implementation.

## Automatic Content Detection

No more configuring content paths. Tailwind v4 automatically detects where your classes are used.

## Container Queries

Native support for container queries is finally here:

css

@container (min-width: 400px) {


  .card {
    display: grid;
  }
}

New configuration format (migration tool available)

Updated color palette

The upgrade is worth it for the performance gains alone.
