Questions tagged [postcss]

PostCSS is a tool for transforming styles with JavaScript plugins. These plugins can support variables, mixins, transpile future CSS syntax, inline images, and more.

PostCSS is used by industry leaders including Google, Twitter, Alibaba, and Shopify. The Autoprefixer PostCSS plugin is one of the most popular CSS processors.

PostCSS can do the same work as preprocessors like Sass, Less, and Stylus. But PostCSS is modular, 3-30 times faster, and much more powerful.
