A CSS image sprite replaces a web control’s individual images with one composite image – a sprite image – which is a collection of multiple images. An image sprite improves application performance by reducing the number of HTTP requests required to obtain images, because a single request to the sprite image loads all images contained within it. HTML elements reference a sprite image with the 'background-image' attribute. Use the 'width', 'height' and 'background-position' attributes to specify the size and offset of an element's sprite.
