CSS Image Sprites
A Basic Implementation
What's an image sprite?
An image sprite is a single asset located within an image sprite sheet. An image sprite sheet is an image file that contains more than one asset that can be extracted from it.
The image above is an image sprite sheet, and each one of those stars is a sprite within the sprite sheet. These sprite sheets are useful because they improve performance by reducing the number of HTTP requests a browser might have to make.
So how do you implement one? Here's some example code.
<div class="icon icon1"></div>
<div class="icon icon2"></div>
<div class="icon icon3"></div>
background-position: 0px 0px;
background-position: -20px 0px;
background-position: -40px 0px;
By using setting the sprite's width and height and by using the background-position property in CSS (with an x and y value) you can easily extract sprites from a sprite sheet using CSS.
