I have been tasked with writing multiple CSS classes for one image. It is basically a social bar that when you hover over the link, the link changes color. There is one image that contains 4 images meant for hover over and one image meant for the default image before hover over. When the user hovers over the image or link, the css coordinates change to be another image within the one jpeg image to show the hovered image. How am I supposed to do this so that it works? The image looks like the following: SEE ATTACHED IMAGE.
