Hello, sorry if my english is poor

I am a beginner creating a wiki for  a card game and I have a display problem on pages using this template (http://krosmaga.wikia.com/wiki/Template:CardPage) in his long form (http://krosmaga.wikia.com/wiki/Yugo)

the problem appear if the page is long enough, uses this template and if the browser's window is maxmized.

it's a black line passing through the category box, the comment box, and so on. I believe that it expend the page too
