PostCSS
A tool for transforming CSS with JavaScript plugins, enabling linting, future syntax transpilation, and more.
What is PostCSS?
PostCSS is a JavaScript-based tool that transforms CSS using plugins. It parses CSS into an Abstract Syntax Tree (AST), providing an API for plugins to analyze and modify styles, enabling tasks like autoprefixing, linting, minification, and future CSS syntax support. It solves the problem of extending CSS functionality in a modular, customizable way without being tied to a specific preprocessor.
Frontend developers and teams building modern web applications who need to automate CSS processing, such as adding vendor prefixes, linting styles, or using experimental CSS features. It is also for tooling authors who want to create custom CSS transformations or integrate CSS processing into build pipelines.
Developers choose PostCSS for its extensive plugin ecosystem (over 200 plugins) and modular architecture, allowing them to build custom CSS toolchains tailored to specific needs. Unlike monolithic preprocessors, it offers flexibility to use only the required transformations and works with various syntaxes like CSS, SCSS, Less, and CSS-in-JS.
