Accessibility

Tools that are easier to use.

The site is designed with labelled forms, keyboard access, visible focus indicators, responsive layouts and text announcements when results change. It uses native browser controls and supports reduced-motion preferences.

Using the site

Use Tab to move between controls and Enter to submit a calculator. A skip link at the top lets keyboard users move straight to the main content. You can zoom using your browser controls; pages reflow on smaller screens.

Known limits

Calculators require JavaScript. Without it, tool descriptions, methods and examples remain readable. Date and time controls vary by browser. Copying results may require HTTPS and browser permission; you can also select the result text manually.
