CSS sprite is a technique to combine
multiple images into one big image (Sprite Sheet). Having multiple small images in your website are less efficient
because each one of those images need to be called in a separate HTTP-Request. Combine them into one Sprite Sheet will
reduce the HTTP-Request to only one and thus will greatly improve your web page loading time. The only drawback, using
CSS Sprite technique is quite time consuming because you have to manually write CSS code for each image in order to
locate its position on the Sprite Sheet.
This is where Quick CSS Sprite comes in. Using Quick CSS Sprite, both sprite
sheet and CSS code can be generated automatically simply using drag and drop.
