Accessibility

This site aims to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA. This statement describes what that means in practice and where it is known to fall short.

What the site does #

Text and controls meet AA contrast in both the dark and the light theme. No text is set below 13 pixels.
Everything works with a keyboard. A skip link leads to the content, focus is always visible, and search (also on Ctrl + K or ⌘ + K) announces its results.
Pages work without JavaScript. Search falls back to a complete list, code and tables scroll inside their own focusable regions, and content reflows at 320 pixels and 200% zoom without horizontal scrolling.
Explanatory diagrams have a text alternative and are followed by a prose description of what they show. The decorative drawing at the top of each page is hidden from screen readers. Interactive explainers come with a static explanation.
Animations are short, never loop, and stop entirely when your system asks for reduced motion.
A button in the header switches between the light and the dark theme. Your choice is stored only in your browser; without it, the site follows your system setting.
Acronyms such as OIDC are linked to the glossary and expanded on first use.

How it is tested #

Every change runs automated checks with axe-core on the main page types at 360, 768 and 1440 pixels in both themes, plus keyboard, reflow, text-spacing and no-JavaScript checks. Automated tools find only part of the problems. A manual pass with VoiceOver on Safari and NVDA on Firefox is part of the release checklist; the first full pass for this design is still to be done, and this statement will be updated when it is.

Known limitations #

Talk slides are linked as PDFs that have not been checked for accessibility. Each talk has a written reading companion in HTML.
