What we have done
- Semantic landmarks, one page-level heading per page and a logical heading order.
- A skip link to the main content, and full keyboard operation of every interactive control.
- A visible, high-contrast focus indicator that is never removed.
- Text and interface colours tested against WCAG AA contrast in both dark and light sections.
- Status is conveyed through text as well as colour. Colour is never the only signal.
- Prominent navigation and form controls designed for touch and keyboard use.
- Form fields with real labels, inline error messages, and an error summary that receives focus.
- Form entries preserved through validation failures and network errors, so nothing is retyped.
- Descriptive text alternatives on every diagram, and decorative artwork hidden from assistive technology.
- Full support for reduced-motion preferences: animation is disabled, not merely shortened.
- Responsive layouts checked for horizontal overflow at narrow viewport widths.
How we tested
Automated accessibility checks use axe on our public routes in desktop and mobile test profiles. Detected violations fail the check. We also test navigation, form focus and narrow layouts. Automated checks cannot establish full accessibility conformance.
Where we fall short
We have not yet completed testing with VoiceOver, NVDA and TalkBack on this version of the site. Full assistive-technology verification remains outstanding.
The technical diagrams carry descriptive text alternatives, but a complex drawing is harder to convey in a short description than a photograph is. Where a diagram carries information that matters, the surrounding text states the same point in prose, so no information exists only in the picture.
If something does not work
When reporting an issue, include the page, your device and browser, any assistive technology, and what you were trying to do.
