Webmaster Forum / HTML, CSS, Scripts / CSS / December 2004What's with three letter colours now?
as opposed to six letter colours? I'm seeing body {color: #fff; background: #000;} and stuff lately. Is this a new form of abbreviation?

Y'know, I took a look at both the HTML 4.01 and CSS 2 specs. The HTML spec says nothing about the length of a hex colour code; the CSS spec says that the code can be either 3 or 6 digits. So I'm not sure what this means: does this mean that the HTML spec can take colour codes of indefinite length: I could find nothing in the spec to either affirm or refute this. * C A Upsdell wrote in comp.infosystems.www.authoring.stylesheets: >>>Part of the HTML spec too.

"A color value may either be a hexadecimal number (prefixed by a hash mark) or one of the following sixteen color names." So if 3-digit codes work in html, it is a browser "feature". Since the color attribute is being deprecated this discussion is irrelevant.

(1) The body of a News article should be related to, but not dependent on, the Subject line. (2) I note that others have, while being keen to score points, not provided an explanation. So see Cascading Style Sheets, level 1 W3C Recommendation 17 Dec 1996 http://www.w3.org/pub/WWW/TR/REC-CSS1 which includes :- 6.3 Color units ... The format of an RGB value in hexadecimal notation is a '#' immediately followed by either three or six hexadecimal characters. The three-digit RGB notation (#rgb) is converted into six-digit form (#rrggbb) by replicating digits, not by adding zeros. For example, #fb0 expands to #ffbb00. This makes sure that white (#ffffff) can be specified with the short notation (#fff) and removes any dependencies on the color depth of the display.
