I had similar thoughts. Another example: the illustrations on the home page are pretty, but they're using terms like "elements", "selectors", "classes". A true beginner has no idea what these are.

I take it these were just a sample that was taken from one of the lessons, but I wonder if there are better beginner-friendly illustrations to start off with on the landing page.

Just a minor suggestion. Otherwise, this looks like a great resource!
