I propose to add following attributes: background-position-left background-position-top background-position-right background-position-bottom so existing 'background-position' will be just a shortcut form of defining 'background-position-left' and 'background-position-top' If both background-position-left and background-position-right are defined for background-repeat:no-repeat images background-position-right wins. Same rule for background-position-top/bottom. For background-repeat:stretch (do not remember exact value) images background-position-left/top/right/bottom define correspondent offsets from padding edge. -- Andrew Fedoniouk. http://terrainformatica.com
