I\'m generating CSS sprites. I want to use these sprites at multiple sizes. I\'ve searched but haven\'t been able to figure out how to functionally scale a CSS sprite--e.g
I know of no way to change the size of a CSS sprite, sorry.
As for generating the CSS Sprites, try: http://spriteme.org/
Or for general image editing: http://www.gimp.org/
You could edit the individual image components, and then use SpriteMe to generate the Sprite. You don't want to generate the sprite and then resize the entire Sprite image, as then your CSS positions for each individual element would be thrown off.
