Existing link colors made it hard to distinguish between visited and
unvisted links on screens that had warmer color temperatures. Adjusted
the colors to make the distinction clear.
Unfortunately, that adjustment made superscript visited links (for
footnotes) fail the APCA, so I added a solid black background to
superscripts. Now they too should have good contrast.
- I felt dark-mode links were still a bit harsh, so I lightened them.
- Improved perceptual contrast of the purple visited links by making the
background color slightly less blue.
- On widescreen, make footer links inline. They happen to be about the
same width as the global nav, which makes this work well.
- microdata for CompleteDataFeed on /posts.html instead of DataFeed
- make the home link <strong> when it's the current page, just like the
other navlinks.
- give code blocks their own figure numbers/names/ID
- Split figcaption into quotecaption and codecaption
- create codefigure partial to reduce markup for SoftwareSourceCode
figures
Create a for <figcaption> and a render hook for code snippets inside
figures, replacing some ugly and complex inline HTML in my markdown
sources.
The only visible change is slightly worse HTML alignment and programming
language indicators (with microdata).
This removed the need to use one of the regex replacements in the
processed_content.html shortcode, and increased the minimum required
Hugo version to 0.93.
Add headings and re-order the items in the article footers to improve
heading-based navigation. Now all sections should have a landmark
recognized by most AT, or a heading.
WCAG recommends telling visitors about their current place in a site's
hierarchy. All pages are exactly zero or one level below a section, so
simply emphasizing a member of the navigation links should be
sufficient.
Some old browser engines don't fully support hyphenation, so they need
some extra help. Now, the entire site should fit in a 150 CSS-pixel wide
viewport.
Clean up some link text too so the text alone is more useful.
