Accessibility

Our target

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

What is built in

• Semantic landmarks, a logical heading order and a skip-to-content link on every page.
• Keyboard operability throughout, including the navigation menu, accordions and the sliders in the worked examples, with a visible focus indicator.
• Body text at a minimum of 17px, colour contrast meeting AA, and touch targets of at least 24px.
• Forms with visible labels, hints and errors associated to their fields; the site works without JavaScript.
• Reduced-motion preferences respected: animations are disabled when your device asks for it. Pinch-zoom is never disabled.
• No content that flashes or auto-plays.

Known limitations

The worked examples on the methods page draw diagrams that update as you move the controls. Each diagram has a text description and the numerical results are also given as text, so nothing depends on seeing the drawing. If you find anything else that does not work for you, please tell us.
