stylus

Stylus is a revolutionary new language, providing an efficient, dynamic, and expressive way to generate CSS. Supporting both an indented syntax and regular CSS style. Installing Stylus is very easy once you have Node.js. So get the binaries for your platform and make sure that they also include npm, Node’s package manager. Stylus features powerful in-language function definitions. Function definitions appear identical to mixins; however, functions may return a value. Optional arguments may default to a given expression. With Stylus we may even default arguments to earlier arguments! Stylus is an innovative stylesheet language that compiles down to CSS. Inspired by SASS, Stylus is built with node.js and capable of running in the browser. Stylus is “pythonic” (i.e. indentation-based). Whitespace is significant, so we substitute { and } with an indent, and an outdent. Stylus, just like CSS, allows you to define properties for several selectors at once through comma separation.
