I wish this video included an explanation of what tabindex="-1" is about. I appreciate the practical tip, but I had to go research why this works elsewhere. I'm just beginning to think seriously about web accessibility, so I don't have any context for how these attributes work.
That is great feedback. I'll do a follow-up on tabindex!
