Accessibility
This site is designed to work without a mouse, on small screens and with assistive technology. If something gets in your way, tell us through the contact form.
Report an accessibility problem
Describe the page, what happened and what you were using.
How the site is built
- Semantic HTML. Headings in order, real lists, tables with headers, and form labels tied to inputs.
- Keyboard operable. Controls are reachable by keyboard, with a visible focus ring and a skip-to-content link.
- Native disclosure widgets. Menu groups and FAQs use
<details>and<summary>, which carry built-in keyboard and screen-reader behaviour. - Contrast. Body text is designed for at least a 4.5:1 contrast ratio and large text 3:1.
- Reduced motion. Animation is turned off when your system requests reduced motion.
- Zoom and reflow. Layouts are designed to reflow on narrow screens and at 200% text zoom.
- Form errors. Required fields are marked in text as well as colour.
Known limitations and how to report a problem
The site targets WCAG 2.2 level AA. One area we know is imperfect:
- Some specification tables are wide and scroll horizontally on small screens.
Reporting a problem
Use the form on this page or the contact form. Tell us the page, what you were using (browser, screen reader, keyboard only, magnification) and what happened.

| 2.4.1 Bypass blocks | Skip-to-content link |
