Help with making a full width page after removing the sidebar

Hi everyone,

I’m currently using the BeautyTemple theme, offered by Awothemes, to design a site for a yoga studio. Unfortunately this site is locally hosted on my computer and will be until it’s completed and ready to go live, so I can’t link it here. That said, I’ll try to describe the issue at hand the best I can.

I deleted the sidebar, however in spite of this, the pages are still aligned left rather than being aligned center and full width. I’ve gone into the Stylesheet and changed some things, but just can’t seem to get everything to be centered and full width. Are any of you familiar with what I might need to change?
