Ecsyle - Roy Lindauer: Very cool CSS technique - CSS Sprites

Very cool CSS technique - CSS Sprites

Everything old is new again, and though the rise of 3D games has made sprite maps obsolete, the concurrent rise of mobile devices with 2D gaming capabilities have brought them back into vogue. And now, with a bit of math and a lot of CSS, we’re going to take the basic concept and apply it to the world of web design.

Specifically, we’re going to replace old-school image slicing and dicing (and the necessary JavaScript) with a CSS solution. And because of the way CSS works, we’re going to take it further: by building a grid of images and devising a way to get each individual cell out of the grid, we can store all buttons/navigation items/whatever we wish in a single master image file, along with the associated “before” and “after” link states.

This is a pretty cool technique, and definitely something to look into.
