Case study 05 / Accessibility
Keyboard-first navigation and focus that never disappears
A UI/UX review method for predictable focus order, visible focus styling, skip paths, and sticky interfaces that do not hide the active control.
The delivery question
Can a visitor understand and complete every task without using a pointer?
A reliable answer has to connect user needs, implementation constraints, and observable acceptance checks. The following practice keeps those decisions visible from discovery through handoff.
Delivery method
From guidance to a testable implementation.
Each layer answers a different question: what the standards require, how the team will build it, and what evidence will show that it works.
Interpret the guidance
- Keep DOM order aligned with visual and reading order instead of repairing navigation with positive tabindex values.
- Provide a visible focus indicator on every interactive element and ensure sticky regions do not cover it.
- Offer a skip link and meaningful landmarks so repeated navigation can be bypassed.
Build the practice
- Map the intended keyboard sequence during wireframing and preserve it in semantic HTML.
- Create one focus-ring token with tested contrast across dark, light, muted, and accent surfaces.
- Test menus, dialogs, filters, and error recovery using Tab, Shift+Tab, Enter, Space, and Escape.
Validate the result
- Automated scans find no obvious keyboard or landmark violations.
- Manual keyboard testing reaches every action in a logical order.
- Focused elements remain visible at supported zoom levels and narrow viewports.
