Mysterious "link has no href attribute" error

[parkr]

I just started testing one of my sites
and it turns out there's an issue with a link having no href attribute. Or does
that mean it's an a tag that has no href attribute?

It's a confusing error – could it be elaborated upon?

Yes, it means an a tag without an href. If I had to guess, this line is throwing Proofer off: <a href="{{ site.github.repository_url }}" class="github">GitHub&nbsp;</a>

Interesting use case. Since the metadata doesn't exist, it renders as href="". You could add data-proofer-ignore to skip it, but I wonder if that's too heavy handed a solution. You or @benbalter have any ideas?

Regardless, since we do now check link tags, I'll update the message to make it clear this is for an anchor.
