Centering content in Wells

Site URL: http://www.ariarosedurward.com

I love the left aligned menu bar in wells, but would like my page content to be centered rather than left aligned next to the menu. On wide screens now there is a large space on the right side of my page and I'd rather have the content centered so this doesn't happen.

Thanks,
Aria

+1 to this topic. Is it possible to provide guidance on how we might center main page content (including menu bar) on Wells? Thank you!
