On this site
- The main pages are checked for WCAG AA colour contrast (4.5:1 for text).
- Every page has a link to skip straight to its content, and one main heading.
- Questions and answers open with the keyboard as well as a click, and the moving product demos stay still when your device asks for reduced motion.
- The pages are written in plain HTML, so browser zoom, reader modes and screen readers work on them as they would on any page.
In the app
- A light and a dark appearance, and a choice of text sizes.
- Icons are drawn shapes rather than emoji, so a screen reader does not read out a symbol's name in place of what the button does.
- On a touchscreen, buttons are sized for a finger, and controls that appear on hover with a mouse are always shown.
- Lectures are spoken and shown as text together, with the words highlighted as they are read.
