alt Hacker NewsWhether you can or can't omit a closing element is one thing, but it seems like a useful thing to be able to quickly determine if some content is inside or outside a tag, so why complicate things?

e.g. how do you think a browser will interpret this markup?
A lot of people think it ends up like this (especially because JSX works this way): but it's actually equal to this:
