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!
