Hmm. For readability, you could ensure the code there is formatted with CSS syntax as shown here. It seems to validate well however, which is interesting.

Judging from Common.css of w:c:the-wandering-inn, you should make sure you're not putting any HTML or anything other than CSS in that page. If you go to an article page in the namespace (no "MediaWiki:" or etc prefix), the CSS should apply to any HTML code you put there.

The lines 1-2 and 10-19 of Common.css need to be removed for your CSS to work.
