The horizontal position is always the negative width of the previous elements combined, and the vertical position is 0px when the mouse is out and -26px (in this example) when then mouse is over. Sprites are two-dimensional images which are made up of combining small images into one larger image at defined X and Y coordinates. So to display the first image, you set background-position: 0 0;. image 91px to the right (#home width 46px + 1px You can use the generated styles in you CSS class. The x postion of the sprite is the horizontal location of the center column of the sprite’s pixels on the screen. Have the sprite say what it’s x and y values are.
