Accessibility

Updated on 22 October 2026.

We want the site to work for everyone, including people who use a screen reader, only a keyboard or a magnified screen. We aim to meet the Web Content Accessibility Guidelines (WCAG 2.2) at level AA.

How the site was built

• Text has a contrast ratio of at least 4.5 to 1 against the background.
• Everything works with a keyboard, with focus always visible.
• Buttons and links are at least 44 pixels, so they are easy to tap on a phone.
• Images have alternative text and diagrams are described in writing.
• Forms have a label on every field and error messages next to the field.
• If your system asks for reduced motion, the site does not animate.
• Pages are tested at 390 pixels wide, with no horizontal scrolling.
