Is it possible to move the body of a profile page to the left (or right)? [closed]

Image for visual example.

I think the body element is called ".main"?
But I'm unsure as to how one could move it, or if that's even possible. I've tried looking up side layouts and all I found were layouts that flip the elements *inside*, such as the links / comments / etc, rather than moving the entire body to the side of the screen.

Thanks all for any help or info.
