Although :active generally only matches while the mouse button is down so
styling 'on click' as in 'this rule will match from the first click on this
element' is not really possible e.g. a transition that begins on :active
will only last for as long as the mouse button is down. I'm suspecting that
what is being requested here is really an equivalent to the onclick event.
