Possibility to add new ways to import fonts in the curriculum

Actually there are other ways to import fonts such as like @font-face (Example):

@font-face {
  font-family: 'MyWebFont';
  src: url('myfont.woff2') format('woff2');

Or alternatives like @import (Example):

@import url(//fonts.googleapis.com/css?family=Open+Sans);

I haven’t finished the entire CSS course, so I don’t know if in some challenge in following topics I will find these ways. If not it would be really good to include these ways on the topics. (Personal Opinion)
