What is built in
- A “Skip to content” link as the first item on every page.
- Semantic page structure: landmarks, a single page heading and ordered heading levels.
- A visible focus indicator on every link, button and form control.
- Colour pairs for text chosen and checked for contrast against their backgrounds.
- Touch targets sized for comfortable use on phones.
- Reduced motion respected when your system asks for it.
- All content readable without JavaScript; expandable sections use native HTML elements.
- Decorative diagrams hidden from screen readers, with their meaning stated in the text.
Where we are
We don’t currently claim conformance with a specific level of the Web Content Accessibility Guidelines (WCAG). We treat accessibility as part of how each page is designed and built, and we fix problems when we find them or when they are reported to us.
