If you have every produced a website for the iPhone, iPad and iPod Touch you will have come across the :hover problem in the Safari Mobile browser for these devices.
Hovering a link cannot be done on these devices as they use 'screen taps' to navigate. So tapping a link that has a hover state will activate the hover (as long as the link does not have a url which will open another page). But you cannot then tap elsewhere to cancel the hover, so the hover state persists until another link is tapped.
