Interaction support
Calculator modes use keyboard-operable tabs with arrow-key movement. Every field has a persistent label, unit, and associated error location. Failed submission focuses a summary whose links move to the affected fields. The result region is marked for polite announcements by assistive technology.
Controls meet a 44-pixel target minimum. Focus indicators remain visible. Layouts collapse to one column on narrow screens without changing the reading order. Browser zoom is not disabled.
Motion and contrast
One short calculation-rail transition confirms a valid result update. The interface removes that motion when the browser reports a reduced-motion preference. Color is not the only indicator of mode, error, or state.
Recorded checks include automated accessibility tests, keyboard interaction, and narrow-screen layout checks. These checks do not establish complete WCAG conformance or coverage of every browser and assistive technology.
Report a barrier
Send accessibility feedback to wooki.support@gmail.com. Include the affected page, the assistive technology or browser when relevant, and a concise description of the barrier. Do not include credentials or sensitive personal information.
