CSS Sprite --active button not working

The :active state is just when you are actually clicking on the element (say, when you are holding down your mouse)

or while the element has the focus and the ENTER key is pressed

In the situation Ralph gave :hover would also apply while for the enter key :focus would also apply.

You can’t have :active without also having one of :hover and :focus
