What is PostCSS

What is PostCSS?

PostCSS is a tool for transforming CSS with JavaScript plugins. These plugins can lint your CSS, support variables and mixins, transpile future CSS syntax, inline images, and more. PostCSS is used by many popular projects, including Bootstrap, Autoprefixer, and CSS Modules.

How does PostCSS work?

PostCSS works by parsing your CSS code into an abstract syntax tree (AST), which is then transformed by plugins. Each plugin performs a specific task, such as adding vendor prefixes, optimizing CSS, or even converting CSS to JavaScript.
