Accessibility statement
Our accessibility commitment (WCAG 2.2 AA), the current state of the site and how to report a problem.
Our goal
We aim to conform to the Web Content Accessibility Guidelines (WCAG) 2.2, level AA, across the whole site.
What is in place
- semantic structure (header, navigation, main content, footer) and a single main heading per page;
- a “Skip to content” link and full keyboard navigation, with a visible focus indicator;
- menus usable with the keyboard (Escape closes them) and by touch, with targets of at least 44 pixels;
- form fields linked to their labels, hints and error messages;
- compliant colour contrast in light and dark modes;
- animations respect the system “reduce motion” setting, and content stays readable without JavaScript;
- a layout that remains readable at up to 400% zoom;
- each page declares its language, and language links state the language of their target.
Known limitations
Calculator results update live; we keep improving how screen readers announce them. No external audit has been carried out yet.
