Bart takes us back to Bootstrap content, now that we know all about breakpoints. He never told us when we were looking at things like margins and float and the display tag that they are also breakpoint-aware, because we didn't know about breakpoints yet. It's an easy lesson and it's great fun to learn more about how responsive design is done with Bootstrap.
