Invalid HTML

[liam-m]

I found that some of the HTML we generate is not valid.

This came up when I was trying to figure out correct xpaths for testing and the tool I was using wouldn't accept the input.

In particular there are divs that are opened but aren't closed.

@Lixquid @ReverateNM could you please fix this?

Going forwards, do we want to add tests for valid HTML to run in CI?

I found a couple of possibilities:

• html_acceptance gem with have_valid_html matcher - configuration required
• headhunter gem - looks awesome - no configuration required, gives a report
