Focus indicator is not reliably visible
Some controls can receive focus without a clear ring. Add a high-contrast :focus-visible style.

Focus Ring & Keyboard Flow Tester
Keyboard accessibility tester for :focus-visible clarity, Tab/Shift+Tab flow, Escape behavior, and modal focus trap. Generate a clear report of where focus gets lost before release.

Keyboard test playground
Use Tab / Shift+Tab to move through controls and open the modal to validate trap behavior.

Tab sequence is inconsistent
Keyboard flow does not follow reading order. Reorder focusable elements or adjust tabindex usage.
Focus escapes modal while dialog is open
Users can tab into the page behind the modal. Implement a strict focus trap for dialogs.
Escape behavior is missing
Modal should close on Escape to match expected keyboard interaction patterns.
Focus does not return after modal close
After closing dialog, return focus to the opener button to preserve orientation.
Skip link is missing or unreachable
Add a skip-to-content link to help keyboard users bypass repeated navigation.
Keyboard accessibility testing: what to check and why
Many accessibility regressions happen during implementation: invisible focus indicators, broken tab sequence, and modal dialogs that leak focus to the background.
How to use: 1) walk through the checklist, 2) test controls with Tab/Shift+Tab, 3) validate modal trap and Escape, 4) log failures and fix before QA sign-off.
Keyboard accessibility FAQ
What is the minimum keyboard QA scope?
At minimum: visible focus ring, logical tab order, Escape close for dialogs, focus trap in modal, and focus return to opener.
Why test modal dialogs separately?
Modals are the most common source of keyboard bugs. Without trap and proper return behavior, users lose context and navigation flow.
Is visible focus alone enough?
No. You need both visibility and flow logic. A visible ring with broken tab order still fails accessibility.
Who should use this report?
Frontend developers, QA engineers, and accessibility reviewers can convert these findings directly into release test cases.
