Floating group alignment

Here is the link to the other post on the issue which I was able to resolve because the content of that page was responsive and was expanding.

My current application has the main content held in a group that is set to not exceed 100% of it’s width. The page is set to expand, but the main content is not, so my previous hack doesn’t work.
