Tailwind CSS 4: What’s New in the Latest Release

Tailwind CSS 4 introduces powerful new features and performance improvements that enhance the developer experience.

Native CSS Variables

Tailwind 4 now uses native CSS variables for theming, making it easier to create dynamic themes.

@theme inline {
  --color-primary: oklch(0.85 0.25 166);
  --color-secondary: oklch(0.80 0.20 200);
}

.button {
  background: var(--color-primary);
  color: var(--color-secondary);
}

Improved Performance

The new engine is significantly faster, with build times reduced by up to 50% in large projects.

Enhanced Color System

OKLCH color space support provides more perceptually uniform colors.

.neon-green {
  color: oklch(0.85 0.25 166);
}

Better Developer Experience

Improved error messages and better autocomplete make development smoother than ever.

Amazing!
