I didn’t have any rigorous training or anything, but my understanding since learning HTML way back in high school was, like the author mentions in TFA, tags like <br> and <p> can simply be used “as-is” as markup and don’t need the concept of being closed.

I write virtually zero HTML anymore, but the one time this sort of thing comes up is in writing PR descriptions in GitHub using Markdown. Sometimes I want to add a <br> or two for space. I guess I’ve never stopped to notice that I never close those tags after adding them, or wondered why in my head it makes sense not to!
