Accessibility Checker
Hi @kovidgoyal

Thanks for the latest update.

I noticed the new Accessibility Checker and wanted to give it a try.

The image shows a <h4> heading. This skips a level as there is no <h3> heading above it, only a <h2>.

It shows an epub:type with no matching Aria role.

The checker didn't pick up on either of these. Something I am misunderstanding?

The heading level checker had a bug, it didnt catch the first heading in a new html file, now fixed.

epub:type without an ARIA role: correct behaviour. epub:type="chapter" matches the role doc-chapter, but ARIA doesn't allow that role on headings, only on things like <section>. Adding it would make the markup invalid, so the checker rightly doesn't suggest it. The real problem is that chapter doesn't belong on an <h4>; it should be on the surrounding <section> or <body>.

Great. Thank you.

Ok, thanks. I added that epub:type as a test, but also I wasn't aware of that requirement.

I've checked using a <section> tag as suggested, and it captured the missing aria role.

Is it expected that it does not work in reverse - have the aria role, but the epub:type is missing?

yes, it is, accessibility relies on aria roles not epub:type, so the checker does not care too much about epub:type

Kovid,

I'd just like to thank you for all the work you're doing. I just looked at the release notes for the latest version and this Accessibility Checker looked really interesting. I'll be testing it out a bit later. Up until now, I've either been ignoring or deleting accessibility stuff in the ebooks I edit because I simply didn't understand how it worked. This will give me an opportunity to figure it out.

Thanks, again.

PS: And, the Content Server updates in this version look really interesting, too. I'm pretty sure I'll be starting to use the Content Server in the next couple of days.
