Not Completely Clear Yet

Challenge: Create a More Complex Shape Using CSS and HTML

Link to the challenge:

I have a question about progress and goals, rather than any technical help. At this point in the curriculum, is one supposed to know the content in this lesson (or any lesson) completely?

For example, someone might understand how/when/why to implement something like a pseudoclass of ::before and ::after when given the instructions, but not provide that as a solution independently yet.

Does that make sense? Awareness vs competence.

No. And it’s doubtful that you’ll everything completely but that’s okay. Developers spend a lot of time looking things up, whether it’s syntax or a snippet.
