Link to the challenge:

There is a known bug with this exercise. You can easily skip to the next.

There is a known bug which means the correct answer can’t be submitted. The <hr> tag is one of a few special “self closing” tags which don’t need a separate or paired closing element, just <hr> by itself is fine.

Please ignore any “workarounds” to get the test to submit, as it’s not valid HTML. The page has a double bug on it — the correct answer is currently not accepted, and it does accept a answer that uses invalid HTML.
