Accessibility
How this site supports accessible use, and how to tell us about a problem.
We want everyone to be able to use this site. We build and test it against the Web Content Accessibility Guidelines (WCAG) 2.2, level AA, and we keep fixing what falls short.
What you can adjust
The accessibility button in the header opens settings that apply to every page and are remembered on your device:
- High contrast
- Text size up to 150%
- More space between letters, words and lines
- Plain headings
- Underlined links
- Reduced motion
The site also follows your device settings for dark or light mode, more contrast, reduced motion and forced colours, and it works with the keyboard alone and at 200% zoom.
Known limits
Embedded videos and files published by third parties may not meet the same standard. Tell us if one of them blocks you and we will provide the content another way.
Tell us about a problem
If something on this site is hard to use, contact us and describe the page and what went wrong. We answer every report.
