.clearfix::after{}

teacher uses only pseudo-class after, is it better to write this way .cf::before, .cf::after { content: " "; display: table; }

.cf::after { clear: both; }

The dlearfix is only needed after the element that contains the floated items.

Besides, what would be the reason for adding a "before" pseudo element that does not include a "clear"?

That article is about dealing with a problem in certain browsers, but it is 7 years old.

There's been a lot of improvement in browsers during that time, I suspect that information no longer applies to browsers in use today. The clearfix taught in the course is pretty much "standard practice" now.
