How to style checkbox using CSS?

You can achieve quite a cool custom checkbox effect by using the new abilities that come with the :after and :before pseudo classes. The advantage to this, is: You don't need to add anything more to the dom, just the standard checkbox.

Note this will only work for compatible browsers, I believe this is related to the fact that some browsers do not allow you to set :after and :before on input elements. Which unfortunately means for the moment only webkit browsers are supported. FF + IE will still allow the check-boxes to function, just un-styled, and this will hopefully change in the future (the code does not use vendor prefixes).

This is a Webkit browser solution only (Chrome, Safari, Mobile browsers)
