I know that this must be a stupid question, but I've been away from CSS for so long that I can't seem to figure this out. I want an image to be my background and fit to the size of the screen, whatever it may be. The problem is that the image appears to be too big as I have to scroll across and down to view it. I know that I could use an image editor and manually rescale the image, but if someone used a bigger/smaller screen than I have, they would experience the same problem. Any help is greatly appreciated.
