Generate CSS For Sprite Images – Sprite Cow
With their increasing popularity, we are seeing more and more CSS sprite generators everyday.
Sprite Cow is another one which is open source and works very effective by auto-recognizing the different elements inside a single image.
So, you design the sprite image in your favorite imaged editing application, upload it to Sprite Cow and simply click (or click + drag) on each element to get their
background-position as a CSS rule.
The application can select items in any size and also gives you the option of changing the background color.
