Forum:Template width

I need help on my wikia. I updated this template (http://vampirediaries.wikia.com/wiki/Template:VD_Episodes) For some reason the first bar is not on its full size. I want it's width t be 100%. In it I added 4 lists and they're small and that's fine. But I want the first bar to be bigger. When I click on any of those 4 show buttons it expands the first bar to 100%. I want that to be the case on first sight. Thanks in advance.
