Accessibility
NumoCrunch aims to meet WCAG 2.2 level AA on every page. Calculators should be usable with a keyboard, a screen reader, magnification or reduced motion enabled.
Keyboard and focus
Every control is reachable with Tab, has a visible focus ring, and each page starts with a skip-to-content link. Interactive targets are at least 44 × 44 px.
Contrast and colour
Text, borders and labels are checked against WCAG 2.2 AA contrast ratios. Progress bars and results are always described with a number and a text label, never colour alone.
Screen readers
Pages use semantic headings, lists and landmarks. Calculator results update in a polite live region, and every visualisation carries a text alternative.
Motion
Animation is limited to subtle hover, focus and entrance transitions, and is disabled entirely when your system requests reduced motion.
