Admin Forum:Styling the main page tally number

This is CSS 101 stuff, but for some reason I'm having no luck with it. I want to affect the style of the tally number and the accompanying MediaWiki:Oasis-total-articles-mainpage on tardis:Doctor Who Wiki, our main page.

But somehow I'm not getting the syntax right. I think the error is simply in the way I'm referring to the page. Which of the following will do the trick?

Or is it something else altogether? I'm not getting much joy out of any of these. Thanks in advance to anyone who can help diagnose. 21:39: Tue 25 Sep 2012
