Bootstrap 4? I can only find a beta version
I am confused. I realised I was using bootstrap 3 when a lot of the classes in your examples did not work. For example the 'display' class for h1 elements and the 'text-xs-center' class for aligning elements.
Unless I am doing something really stupid... why is there a course on Bootstrap 4 if it hasn't been released?

Bootstrap 4 is in its second Alpha release... which means that it's stable enough to make available to the public, but unstable enough for use in the production code of important web apps.
It's fine to use for the purposes of learning Bootstrap, and therefore for the purposes of this course.
