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.

Installation

$ npm install stylus -g

Example

border-radius()
  -webkit-border-radius: arguments
  -moz-border-radius: arguments
  border-radius: arguments

body a
  font: 12px/1.4 "Lucida Grande", Arial, sans-serif
  background: black
  color: #ccc

form input
  padding: 5px
  border: 1px solid
  border-radius: 5px

compiles to:

body a {
  font: 12px/1.4 "Lucida Grande", Arial, sans-serif;
  background: #000;
  color: #ccc;
}
form input {
  padding: 5px;
  border: 1px solid;
  -webkit-border-radius: 5px;
  -moz-border-radius: 5px;
  border-radius: 5px;
}

the following is equivalent to the indented version of Stylus source, using the CSS syntax instead:

border-radius() {
  -webkit-border-radius: arguments
  -moz-border-radius: arguments
  border-radius: arguments
}

body a {
  font: 12px/1.4 "Lucida Grande", Arial, sans-serif;
  background: black;
  color: #ccc;
}

form input {
  padding: 5px;
  border: 1px solid;
  border-radius: 5px;
}
