See attached. I want to lay out this page in Bootstrap.
Ignore the items in Red Text.
I was thinking of a column layout like (sm-4 sm-2 sm-6 and xs-4 xs-2 xs-6).
The left columns are obvious.
I can't see how to make the upper right extend as natural columns to the right. I think I need something like the old "rowspan" of html columns.
How can I do this in bootstrap?
