回答1:

I usaully use the CSS background property. This property allows you to set a scroll argument of top and left as you can see in the example below. So the idea is to create one image with all states and simply position it based on the event like hover or other custom event in which you alter the elements CSS. I hope this helps.

.mySprite a
{
    background: transparent url(/images/spriteButton.gif) no-repeat scroll 0 0
}

.mySprite a:hover
{
    background: transparent url(/images/spriteButton.gif) no-repeat scroll 30 0
}

If you are using Firefox here is a simple way to get an idea of what a sprite is. Go to yahoo.com, right-click and View Page Info, click Media. Look for a file name having "sprite" in it.

This is one of the links: http://d.yimg.com/a/i/ww/met/gsprite_071309.gif

You will see many background gradient images. You can use this file to play with. Now you have to adjust background position in your CSS depending on which background you want to use, like this:

background-image: url('http://d.yimg.com/a/i/ww/met/gsprite_071309.gif') left -30px repeat-x;

This should give you an idea of how to manage sprites.

I use them for button images. I use the top half of an image for the normal button state and the bottom half for the mouse-over state. That way the mouse over image is loaded when the page loads and there's no delay which just looks bad and slow. CSS code is here.
