Widen Content/Sidebar Containers

Hi all,

I’d like to widen the content container and sidebar container.

More explanation:

My blog is currently in the “boxed” layout. Even when it’s at the “full” layout, it just erases the gray on either side of my content/sidebar without stretching widening the containers to fit the screen.

How do I adjust the width of the main content container, and the width of the sidebar? So, for example, if I wanted to add more social icons in my sidebar, they wouldn’t be moved to the next line, but would all appear on the same line.

My site is http://www.somesundrytales.com

Thanks,
Amanda
