FAQPage Schema

How do I implement focus trapping in an accessible modal dialog?▼

Accessible alert dialogs require proper ARIA attributes like role="alertdialog" and aria-labelledby to announce urgent content. This Skill provides specific guidance on handling alert dialogs, filter patterns, and non-modal dialogs for screen reader compatibility.

Does the native HTML <dialog> element meet WCAG AA accessibility standards?▼

The native HTML <dialog> element can meet WCAG AA standards when implemented with correct focus management and ARIA attributes. This Skill offers specific guidance on native <dialog> usage, including aria-modal and aria-labelledby, across any web framework or vanilla HTML/CSS/JS.

Why does focus not return to the opening button after closing a modal?▼

Can I use this modal accessibility guidance for vanilla JavaScript projects?▼

Screen reader announcements for overlays require proper ARIA attributes like aria-modal and aria-labelledby to function correctly. This Skill ensures overlays meet WCAG AA standards by managing focus trapping, keyboard operability, and screen reader announcements for popovers and sheets.
