How can I change my Character Sheet's information from being inside 2 columns?

I really don't like that the information in my Character Sheets is inside columns. It gives you very little room to type all this information on your character, and then there's all this space off to the side. Can't I just have it be inside one column? How can I fix this?? I am using phpBB3. Is there at least a code I use that will alter this?

Here is what I mean. See how it's all divided to one side and cannot cross over any farther? The boxes need to stretch all the way over.
