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
```bash
$ npm install stylus -g
```
## Basic Usage
Watch and compile a stylus file from command line with
```bash
stylus -w style.styl -o style.css
```
You can also [try all stylus features on stylus-lang.com](http://stylus-lang.com/try.html), build something with stylus on [codepen](http://codepen.io) or [RunKit](https://npm.runkit.com/stylus)

### Example
```stylus
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:
```css
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:
```stylus
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;
}
```
