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

PostCSS is used by industry leaders including Wikipedia, Twitter, Alibaba,
and JetBrains. The [Autoprefixer] PostCSS plugin is one of the most popular
CSS processors.

PostCSS takes a CSS file and provides an API to analyze and modify its rules
(by transforming them into an [Abstract Syntax Tree]).
This API can then be used by [plugins] to do a lot of useful things,
e.g., to find errors automatically, or to insert vendor prefixes.
