What'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?

New? Hasn't it always been part of the css specification?

Part of the HTML spec too. But beware: some old browsers can't handle
the 3-digit colours.

Which HTML spec (and according to which section in that spec?)

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.

Yes, it was introduced only about ten years ago. :-)

"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.
