Accessibility

Automated check tagged to a WCAG 2.2 AA edition. Not a statement that the site meets a standard.

This firm sells accessibility testing, so this page describes what the site actually does rather than what it hopes to. Checked on the build you are looking at.

What it does

  • A skip link is first in the tab order and moves focus to the main content.
  • The front door is ordinary server-rendered HTML: one heading and one action. Nothing on it needs scripting to read or to use.
  • The contact form labels every field, marks the one optional field, and opens your own mail program. It does not send data to this site.
  • The not-found page has a search. It is a proper combobox: arrow keys move through matches, Enter opens one, Escape clears. The active match is exposed through aria-activedescendant, and a polite live region announces how many matches there are. The full index is in the HTML underneath it, so with scripting off everything is still there.
  • Every move between pages is a plain link. Nothing needs a mouse, a drag, a hover, or a gesture.
  • Focus is visible: a 2px outline offset from every link and button, and the search field changes its border when it has focus.
  • The front door does not show the contour field. On the other pages the field runs only when WebGL is available and reduced motion is off. The blinking caret, the cycling placeholder, the scroll-driven reveal of the method diagrams, and the transitions between pages stop under the operating system’s reduced-motion setting and under the “reduce motion” control in the header, which is remembered in this browser.
  • Colour is never the only signal. Links inside sentences are underlined, decision points in the method drawings are labelled “Decision” in text, and the active search match is marked with aria-selected.
  • Wide drawings on the practice pages scroll sideways inside their own frame. That frame takes keyboard focus, so the arrow keys can scroll it.
  • Contrast on the paper ground: body ink 11.9:1, quieter text 8.5:1, the green used for interaction 6.3:1, the red used for links 5.7:1. The front door reverses that ink and paper, so the body pair is the same 11.9:1. WCAG AA asks 4.5:1 for text.
  • The layout reflows down to 390 pixels wide without sideways scrolling, so 200% zoom on a laptop works.
  • Pages use landmarks (header, main, footer), one first-level heading each, and declare their language.

What it does not do yet

  • It has not had a third-party audit. Each build runs an automated scan tagged to a WCAG 2.2 AA edition, and the pages are keyboard-operable. That scan is a floor. It is not a statement that the site meets a standard, and it is not a VPAT.
  • Page transitions only run in browsers that support cross-document view transitions. Everywhere else, navigation is ordinary, which is the intended fallback.
