Accessibility statement
-----------------------
-I've made every effort to make seirdy.one as accessible as possible. More information about the accessibility-related work for seirdy.one is in my post {{}}{{}}{{}}.
+I hold seirdy.one to the highest accessibility standards possible. For more information about seirdy.one's accessibility-related work, read {{}}{{}}{{}}.
### Conformance status
-The [Web Content Accessibility Guidelines (WCAG)](https://www.w3.org/WAI/standards-guidelines/wcag/) defines requirements for designers and developers to improve accessibility for people with disabilities. It defines three levels of conformance: Level A, Level AA, and Level AAA. I've made sure seirdy.one is **fully conformant with WCAG 2.2 level AA.**

-I also go further than WCAG in many aspects:
+The WCAG presents a starting point, not a stopping point. Here are some non-WCAG accessibility criteria I consider:
-- Rather than follow SC 2.5.5's requirement to achieve a minimum tap target size of 44 by 44 pixels, I follow Google's more strict guidelines. These guidelines mandate that targets are at least 48-by-48 pixels, with no overlap against any other targets in a 56-by-56 pixel range. I try to follow this guideline for any interactive element that isn't a hyperlink surrounded by body text.

-- With the exception of in-text borders, I only set custom colors in response to the `prefers-color-scheme: dark` media query. These custom colors pass APCA contrast ratios, all being close to the ideal lightness contrast of 90. They are also autism- and overstimulation-friendly colors: the yellow links are significantly de-saturated to reduce harshness.

-- I ensure that the page works on extremely narrow viewports without triggering two-dimensional scaling. It should work at widths well below 200 CSS pixels.
+- I ensure narrow viewports don't cause two-dimensional scrolling. I test this at widths narrower than 200 CSS pixels; this is much stricter than the WCAG threshold values.
### Assessment and evaluation
-I test each WCAG success criterion myself using the mainstream browser engines (Blink, Gecko, WebKit). I test using multiple screen readers: Orca (primary, with Firefox and Epiphany), NVDA (with Firefox and Chromium), Windows Narrator (with Microsoft Edge), Apple VoiceOver (with desktop and mobile Safari), and Android TalkBack (with Chromium).

Compatibility statement
-----------------------
-The website is built on well structured, semantic, [polygot XHTML5](https://www.w3.org/TR/html-polyglot/) (including [WAI-ARIA](https://www.w3.org/WAI/standards-guidelines/aria/) and [DPUB-ARIA](https://www.w3.org/TR/dpub-aria-1.1/) extensions where appropriate), enhanced with CSS for styling. The website does **not** rely on modern development practices such as CSS Grid, Flexbox, SVG 2, Web fonts, and JavaScript; this should improve support in older browsers such as Internet Explorer 11. No extra plugins or libraries should be required to view the website.
