Widget Break between posts.

Hi, how do you do these widget breaks between posts I’ve seen on blogs. You’ll have your body content, then you’ll have a horitzonal featured section within the content, then resume regular content format again.

I’ve been looking into shortcodes – these tutorials seem to be for posts and pages. Maybe I’m trying to add widgets in breaks between content? Can anyone provide help with this? I’m not asking for the code, but just what I should be looking at, what sort of code this would be.

PS. Example. I don’t know if this is wordpress but TheVerge.com has these horizontal scroll areas in the page. I want something like that.
