[Mediawiki-l] background color change

[aretai aretai]

Hi,

I tried to find sth on how to change the background for some of the pages in
my wiki (talk, discussion, etc) and also special pages, but I couldn't. I
tried to do some css stuff, but only achieved changing the background of the
wiki itself.

Maybe anyone knows how to do it? I'm not interested in changing part of a
wikipage (by for example placing a table), but the entire wikipage. Or just
point me where it is discussed.

Regards,
Aretai
