Uniform v1.5
Copyright © 2009 Josh Pyles / Pixelmatrix Design LLC
http://pixelmatrixdesign.com

Requires jQuery 1.3 or newer

Much thanks to Thomas Reynolds and Buck Wilson for their help and advice on this

Disabling text selection is made possible by Mathias Bynens <http://mathiasbynens.be/>
and his noSelect plugin. <http://github.com/mathiasbynens/noSelect-jQuery-Plugin>

Also, thanks to David Kaneda and Eugene Bond for their contributions to the plugin

Usage:

$(function(){
  $("select, :radio, :checkbox").uniform();
});

You can customize the classes that Uniform uses:

$("select, :radio, :checkbox").uniform({
  selectClass: 'mySelectClass',
  radioClass: 'myRadioClass',
  checkboxClass: 'myCheckboxClass',
  checkedClass: 'myCheckedClass',
  focusClass: 'myFocusClass'
});

Enjoy!
