STATE: well tested and stable

This project uses semver.org standard version numbering.

Sheet.js

Parse CSS in JavaScript

• Test-first Development
• UniversalJS
• Zero dependencies
• DOM-less (no document necessary)
• CommonJS Modules 1.0+ with global fallback
• Browser support
• Implements W3C document.styleSheets API
• Implements WebKit CSS Animation API

Flexible Parsing

• Supports WebKit CSS Animation syntax
• Supports custom selectors, @rules, properties and values
• Supports nested rules
• Supports HTML style attribute values
  i.e. CSS rules without the selectors and brackets

Coming Soon…

• Support for custom CSS-like languages like the Sass 3.0 SCSS (Sassy CSS) and Less CSS

Basic Usage

ClientSide / Browser Usage

var myStyleSheet = new Sheet("#selector { color:blue }");
myStyleSheet.cssRules[0].style.color; // blue
// etc…

ServerSide / CommonJS Usage

require.paths.push('path/to/Sheet.js/Source'); // You might not need this
var Sheet = require('Sheet').Sheet;

var myStyleSheet = new Sheet("#selector { color:blue }");
myStyleSheet.cssRules[0].style.color; // blue
// etc…

Advanced ClientSide Namespacing

If you need to move Sheet.js to its own custom namespace simply define a global exports object before loading Sheet.js. Sheet.js will see that object, assume that it's in a CommonJS environment and then attach itself onto that object instead of including itself globally.

You really shouldn't need to do that. But isn't it great to know you could?
