Link targets need to be focusable to work with VoiceOver.
Making <main> focusable causes some side-effects, like making the TAB
key go to the beginning of <main> instead of the element after the
currently-clicked region.
Also removes the annoying outline around "main" in some non-mainstream
browsers, without having to add extra CSS.
The site now has polygot markup and can handle both XHTML5 and HTML5
parsing rules. My staging site will be XHTML but my main site will be
HTML5, just in case of parse errors.
If other tools (e.g. LightHouse) end up supporting XHTML5, I'll consider
switching the content-type to XHTML.
Some article extractors get confused when the article body references
another author with microdata. Declare the author itemprop a second time
to make them happy.
- Stop using draft WAI-ARIA 1.3 that isn't supported yet
- Make in-page links focusable across shortcodes/partials
- Replace existing in-page heading anchor links with a more accessible
option.
- Make backlinks aria-labelledby instead of giving them an aria-label,
so they can be translated.
Split up some verbose and repetitive templates to use nested templates.
Cache some templates that don't need to be re-built every time.
Reading time: switch "a" to "an" when followed by the number "8".
Improve whitespace alignment a bit.
