We can make this file beautiful and searchable if this error is corrected: It looks like row 2 should actually have 3 columns, instead of 1. in line 1.

Created January 8, 2012 20:58
CSS parsing in JavaScript
/**
* This is the light version of Danial Wachsstock's jQuery based CSS parser
* http://bililite.com/blog/2009/01/16/jquery-css-parser/#parserdetails
*
* Everything is removed but the core css2object parsing
*
* Usage is straight forward:
*
* $.parseCSS('body { background: red; font-weight: 300 }');
* // returns { 'body': { 'background': 'red', 'font-weight': 300 } }
