Could the background-color properties be enhanced to support two digit/character shorthand? For example, instead of having to write out:
background-color: #f9f9f9;
– we could just put:
background-color: #f9;
– and CSS3 automatically create/interpret the triplet?
This could even extend to single char declarations:
background-color: #f; (white)
background-color: #0; (black)
Granted, this only applies to differing shades of grey, but it would still be helpful I think.
