Tailwind CSS

tailwindcss.com

Utility-first CSS framework that lets you build designs directly in your HTML without writing custom CSS.

Best for: Any vibe coding project — Tailwind has become the default styling layer for most AI-generated code Free and open source
Key Features
  • Utility-first approach — style elements by composing small, single-purpose classes
  • Default for most AI coding tools (Cursor, Lovable, v0, Bolt) — output is already in Tailwind
  • Large ecosystem of component libraries built on top of it
Limitations
  • HTML can become verbose with many utility classes
  • Initial learning curve for developers accustomed to traditional CSS approaches
  • Requires build step for production optimization (PurgeCSS)
