Accessibility

Accessing calculators

The interface uses labeled controls, semantic headings, visible keyboard focus, text error messages and result announcements. A skip link moves directly to the main content. Buttons are designed for practical touch use, and pages adjust to narrower screens.

Keyboard search

Type a calculator name in search. Use Tab to move between controls, or press the down arrow to focus a matching result. Enter follows a focused calculator link. Escape clears the search and returns focus to the input.

Appearance and printing

Choose Light, Dark or System in the header. System follows your operating system’s preference. Print styles remove navigation and retain calculation content. Results include text values; graphical comparisons are supplementary.

Known limits

Some calculation tables need horizontal scrolling on smaller screens. Clipboard, storage and sharing features depend on browser permissions and support. Automated checks cannot establish full WCAG conformance; assistive-technology and user testing remain important.

Feedback

Use the contact page to prepare a report describing the page, browser, assistive technology and difficulty. The report is created locally and must be forwarded through the operator’s published contact channel.
