Emmet is incredibly useful for typing repetitive chunks of code, and just freeing time for more important tasks. It’s pretty beginner friendly too, the syntax is almost like the normal html/css.
I noticed an old topic saying that HTML course Editor has it turned on. Only thing I can say is that Responsive Web Design (beta) doesn’t have it, and it doesn’t even add the end tag after closing the start one.
Is this done on purpose? To make the newcomers type more, and develop muscle memory for coding or something? If not, Emmet would be amazing.
