Detect screen size

I'm working on a  "full screen, background image based" website that looks pretty bad on mobile since the pictures don't shrink as small as I need them to on mobile.

I'm basically looking for a javascript that can detect if the screen is smaller than ex: 800x500 and provide a certain div with a different class than the one assigned too it.

That way a different class will load depending on the users screen size.

Thanks
