Sidebar and main concent area together

Dear Colorlib Staff,

I love your theme, but I miss a feature that I’m sure it’s attainable through CSS modification. I’d like to have the main content area and the sidebar together (without any space between them. Please, see attached my idea.

What CSS would I need for this?

Dear Sparklinkg Staff,

I don’t know if my previous post was published, so I try again just in case. Is there any CSS way to put together the main content area or the sidebar? (without any space between them, sharing the same border).

Thanks in advance for your help!
