Nope.  Assuming that the CSS background is "pure presentation" and doesn't
convey any information which could be included but isn't.  (The lack of
longdescs for such background images -- indeed, all background images
-- is a bit bothersome, though.)

Question:  Some sites might use a logo as a background image, perhaps
lightly tiled, perhaps large and centered as a watermark using CSS.
Is it necessary to include some notation of this, and if so, what is
the best way to do it?  Some content/meaning _is_ conveyed through
this CSS, but it may not be something which is worth capturing in
markup.  A longdesc or the equivalent -may- prove useful to blind
users who are communicating with non-blind users, but only to a
limited extent.

Should I have some sort of description on my page (kynn.com) of the
graphical/visual elements of the page, for the benefit of those who
cannot see the CSS?  (This isn't a specious question; I choose my
CSS colors deliberately and seasonally, and there's no other non-
graphical clues to say "this is a christmas design" or "this is an
aubergine design" or "this is an autumn design" without seeing the
page itself in a CSS browser.)

(I suspect the answer is "no, you don't have to" but it might be
useful, perhaps even just with CSS comments.)
