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.

What are postcss's main functionalities?

Autoprefixing

Automatically adds vendor prefixes to CSS rules using values from Can I Use. It is recommended by Google and used in Twitter and Alibaba.

postcss([ require('autoprefixer') ]).process(css).then(result => { result.warnings().forEach(warn => { console.warn(warn.toString()); }); console.log(result.css); });

CSS Variables

Transforms CSS Custom Properties (CSS variables) syntax into a static representation that can be understood by browsers that do not support this feature.

postcss([ require('postcss-custom-properties') ]).process(css).then(result => { console.log(result.css); });

CSS Nesting

Allows you to nest one style rule inside another, following the CSS Nesting Module Level 3 specification.

postcss([ require('postcss-nesting') ]).process(css).then(result => { console.log(result.css); });

Minification

A modular minifier, built on top of the PostCSS ecosystem. It is used to minimize CSS for better performance.

postcss([ require('cssnano') ]).process(css).then(result => { console.log(result.css); });

Future CSS Syntax

Allows you to use future CSS features today. It polyfills CSS features that are not yet fully supported in browsers.

postcss([ require('postcss-preset-env') ]).process(css).then(result => { console.log(result.css); });
