is this type of border possible with CSS

Hi,

I can handle doing a border on a div where it's just a rectangular border encompassing the div but is the type of combo border possible as in this picture?

Its like a rectangular border around a div and then combined with a horizontal rule that splits the rectangular div horizontally but the horizontal rule is not visible inside the div but only outside it.

I don't know if this type of border has a name or if it is possible via CSS.
