PostCSS: Tool for Transforming CSS with JavaScript Plugins

PostCSS is a tool for transforming CSS with JavaScript plugins. It allows you to lint, auto-prefix, minify, inline images, and more with many community plugins. It is fast, flexible, and helps modularize CSS.

What is PostCSS?

PostCSS is a tool for transforming CSS with JavaScript plugins. It allows developers to modularize and manipulate CSS in a variety of ways:

  • Lint CSS for errors, inconsistencies, and following best practices with plugins like Stylelint
  • Auto-prefix CSS so it works across different browsers with Autoprefixer
  • Minify CSS to reduce file size with cssnano
  • Inline images and fonts with postcss-assets
  • Modularize CSS with things like CSS modules and cssnext
  • Transform CSS in other ways like fallbacks, aliases, and more with community plugins

PostCSS is fast, flexible, and allows writing CSS in future CSS syntaxes before they are widely supported. It helps keep CSS DRY, maintainable, and scalable by allowing logic and transformations with JavaScript. The vibrant plugin ecosystem enables many transformations without writing much custom code.
