I'm having a little trouble with the style window, i wish to change it so that the layout will be of a wide /thin layout but i can't find the code for it anywhere in the .css or any other place. Is there any way to change the body. for an example of what is currently happening you can view the page here

the window cuts off the text (because its a table) but i want the window to be larger.

Thanks in advance.
