Accessibility target
The project targets WCAG 2.2 Level AA. That target guides semantic HTML, labels, colour contrast, focus visibility, keyboard access, responsive reflow, error handling, touch targets and alternatives for visual content. It is a continuing standard, not a claim that every possible barrier has already been found.
Current accessibility measures
- A skip link and logical heading structure.
- Labelled controls with visible instructions and linked validation messages.
- Keyboard focus management for dynamic calculator rows and errors.
- Layouts tested for narrow screens and text reflow without horizontal page scrolling.
- Exact text results and fallback descriptions alongside Canvas visualisations.
- Calculations that do not depend on colour or the visual preview.
Testing status and known work
Automated WCAG checks, keyboard-only navigation and text-spacing stress checks have been completed on the core pages. Further screen-reader, browser-zoom and Australian user-comprehension reviews remain part of ongoing testing. Automated tools do not replace manual checks.
