A more succinct syntax could extend the current format of #rgb or #rrggbb to include #rgba or #rrggbbaa like so: .my-color { color: #ffffff80; /* half white */ } The browser could easily detect the difference between a 3 or 4 character hex value, or a 6 or 8 character hex value, and implement the alpha channel as appropriate. 370266 1 mikelawther 2011-03-20 20:35:56 -0700 This is not in the spec. Perhaps ask www-style@ for their opinion. 372285 2 abecsi 2011-03-23 11:31:55 -0700 *** This bug has been marked as a duplicate of bug 39140 ***
