Accessibility

FBM Calculators Hub aims to follow WCAG 2.2 AA principles. Pages use semantic headings and landmarks, visible labels, keyboard-operable controls, visible focus states, and text explanations that do not require a chart or color to understand.

Inputs use native browser controls and appropriate input modes. Validation errors are announced, result changes use a polite live region, and reduced-motion preferences suppress non-essential animation.

Browser, assistive-technology, zoom, and device combinations vary. If a label, focus order, contrast, menu, result announcement, or touch target prevents use, report the page and problem through the Contact page so it can be reproduced and corrected.
