Accessibility

This site aims to meet the Web Content Accessibility Guidelines (WCAG) 2.2 at level AA.

What we do

• Every diagram has a text alternative, and the main diagram can be read as a list.
• The site can be used with a keyboard alone, with a visible focus indicator and a skip link.
• Text colours meet AA contrast; colour is never the only way information is shown.
• Animation is minimal and switches off when your device asks for reduced motion.
• Pages work without JavaScript; the publication filters and search add to them.
