It takes as much energy to wish as it does to plan. — Eleanor Roosevelt
I don't see image sprites used that much anymore, but it's still a good technique for reducing downloaded decorative image assets when you have multiple on a page. The big idea is combining all the graphics into one and then shifting around the size and background-position to reveal one at a time.

display: block;
height: 30px;
