Forum:Help with infobox

I need some help with some infobox. As you can see the infobox on this page, it doesn't contain an border on the right and left side (the vertical border). Now, I want this this image to server as the vertical border in the infobox. I've imputted the image on my mediawiki:common.css page as "PPborder", but I don't know how to do that. -- Darth Stefan Talk http://images3.wikia.nocookie.net/lostpedia/nl/images/e/e5/Stefan_handtekening.PNG  14:07, May 14, 2010 (UTC)
