Our aim
We aim to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA.
What we build in
- Colours and text styles are chosen with readable contrast in mind.
- Navigation and controls are designed for keyboard use, with visible focus indicators.
- Headings and landmarks describe the structure of each page.
- Images and diagrams have text alternatives, and decorative graphics are hidden from screen readers.
- Where motion is used, reduced-motion styles respond to your device’s setting. The home page content does not depend on animation.
- Responsive layouts and scalable text support reading on narrow screens and at larger text sizes.
- Text, labels and shapes supplement colour where it conveys meaning.
How we test
We aim to check contrast, text size, reflow and keyboard focus across different screen sizes and browsers. Automated checks are only part of that process and do not establish full WCAG conformance. Browser and assistive technology differences can reveal issues that were not found in review; please tell us if you encounter one.
Known limitations
- The engineering lab includes scripted walkthroughs, working browser examples and calculators. These interactive features need JavaScript.
- Interactive demonstrations may need extra testing with your browser or assistive technology. Their surrounding text describes the concepts, but may not provide an equivalent experience for every control.
