Tailwind CSS: Utility-first CSS framework for UI development
PostCSS framework generating utility classes from scanned templates.
Learn more about Tailwind CSS
Tailwind CSS is a CSS framework built on PostCSS that generates utility classes for styling web interfaces. It works by scanning template files for class names and generating only the CSS needed for those classes, reducing file size through purging unused styles. The framework includes responsive design utilities, state variants for hover and focus states, and a configuration system for customizing the default design tokens. It is commonly used in web development workflows with modern JavaScript frameworks and static site generators.
Utility-First Class System
Composes styles directly in markup using single-purpose CSS classes instead of writing custom stylesheets. Eliminates context switching between HTML and CSS files while maintaining consistent design patterns across components.
PostCSS Plugin Architecture
Integrates into existing build pipelines as a standard PostCSS plugin. Works alongside other CSS tooling and generates optimized output by scanning templates to include only classes actually used in production.
Configurable Design Tokens
Centralizes colors, spacing, typography, and breakpoints in a single configuration file. Generated utility classes automatically reflect custom design system values without manual CSS updates or overrides.
