Accessibility

This site targets WCAG 2.2 Level AAA. Where a criterion is not met, it is named below rather than omitted.

What is in place

  • Text contrast of at least seven to one against its background, in all four reading themes.
  • Line length capped below eighty characters, with line and paragraph spacing set for readability.
  • Four selectable reading themes, including a high-contrast option.
  • A summary in plain language at the top of every substantive page, in a labelled box.
  • Every interactive target at least forty-four by forty-four pixels.
  • Link text that describes its destination without relying on surrounding words.
  • Nothing that moves, auto-advances, or interrupts. No pop-ups and no time limits.
  • The contact form shows you exactly what will be sent and asks you to confirm before sending.
  • Full keyboard operation, with a visible focus indicator that is never obscured.
  • A glossary, linked from technical terms on first use.

Known exceptions

The W3C does not recommend Level AAA as a blanket policy for entire sites, because some criteria cannot be met for some content. These are the places this site falls short, and why.

3.1.5 Reading Level
The doctrine documents are written for a professional audience and exceed lower secondary reading level. The plain-language summary at the top of each page is the supplementary version this criterion allows, but it summarises rather than replaces the argument.
1.2.6 Sign Language and 1.2.8 Media Alternative
Archived talks link to third-party video hosted elsewhere. Captions are not under this site’s control, and no sign language interpretation is provided. A written summary accompanies each.
1.4.9 Images of Text
Documents linked from external sources may contain images of text. Those documents are not authored here. The name at the top of every page is also drawn rather than typed: the criterion exempts logos and brand names, and that exemption is what is relied on. Its accessible name is real text, so a screen reader announces it normally, and it scales with the page rather than blurring.
1.4.8 Visual Presentation, on the contact card only
Every page here lets you choose your own foreground and background from four reading themes. The contact card, which is reached only by scanning the QR code on his printed card, does not: it is fixed to the dark theme, so that everyone handed the same card sees the same thing. If your device asks for increased contrast, that page switches to the high contrast palette on its own, without a control to find. The dark theme it otherwise uses measures 15.6:1, which is more than twice what Level AAA requires.

How this was assessed

Automated checks run against every deployment and block it if they fail. Automated testing catches perhaps a third of real barriers, so manual keyboard and screen reader testing is done as well. This statement is reviewed whenever the site changes materially.
