[Mediawiki-l] can't get custom css codes to work?

[inhahe]

hi, i'm having a problem changing the spacing between paragraphs.
i tried putting
p {margin-bottom: 1.5em}
in [[MediaWiki:Common.css]]
but nothing changed.
(i tried different em values too)
so i looked at the source code of a page to see where common.css is
included, and tried navigating directly to that link
the link contains "action=raw", but when i navigate to it i get the same
thing as when i navigate to [[MediaWiki:Common.css]] rather than the raw
text.
so that might be why the code isn't working, but i don't know why it's doing
that.
i also tried putting the css code at the bottom of shared.css, but nothing
happened there either.

i'm using MediaWiki 1.14.0, php 5.2.0, and abyss x1 as my webserver.
