I added a widget (a comment box) to my wiki and although it works perfectly, I can't figure out how to change the font size. Can someone tell me how to fix this? The mediawiki can be found here:

http://pathinfo.wikia.com/wiki/MediaWiki:CommentBox2

And a page where I have added the comment box can be found here (bottom of page):

http://pathinfo.wikia.com/wiki/Pathology_Job_Wiki

On the page where I got the widget, htmlcommentbox.com, it says you must use css to change the font size. I tried modifying the css and linking the code to the wikia css page, but I couldn't figure it out.

(On a side note, if you know of  comparable feature on wikia, I'd be glad to use it.  The only "comment box" I could find, however, created a new page whenever someone commented). Thanks in advance for your help.
