PostCSS

PostCSS is a small utility that can create something that mimics JavaScript's source maps feature, but for CSS code.

Just like the JS version, a CSS source map is a way to map minified code back to its uncompressed state.

CSS source maps will allow developers to easily modify production-ready CSS code that usually gets delivered in a minified form, making modifications at runtime without beautifying the code in advance.

PostCSS is capable for rendering its own source map for the changes developers make, and even also update a source map from previous steps.

The library leaves code formatting in its original form, and also support common pre-processors like Stylus or SASS.
