Accessibility

This website is designed to meet the Web Content Accessibility Guidelines version 2.1 at level AA. It uses semantic HTML, a visible keyboard focus indicator, colour contrast that meets the AA threshold for text, and layouts that reflow down to a 320 pixel viewport.

Motion is reduced automatically for visitors whose system requests reduced motion, and all content remains available with JavaScript disabled.

We are reviewing the contrast of decorative graphics in the page headers.

If you meet a barrier on this website, write to [email protected] with the page address and a short description. We will reply and tell you how we plan to fix it.
