Quick Reference
Element Code: AC-016
Issue: ARIA container roles are missing required child elements
Impact: Incomplete accessible structure that may confuse assistive technologies
Fix: Add required child elements with appropriate ARIA roles
Detection: axe DevTools, ARIA validators
What Is This Issue?
Some ARIA roles require specific child roles. For example, role="list" must contain role="listitem" children, and role="menu" must contain role="menuitem" children. Without proper structure, the accessibility tree is incomplete.
Why This Matters for Your Website
ARIA creates a semantic structure that assistive technologies rely on. Incomplete structures break navigation and comprehension for screen reader users.
How to Fix This Issue
- Check ARIA spec: Verify required children for each role
- Add missing children: Include elements with correct roles
- Consider native HTML: Often simpler than ARIA
Tools for Detection
- axe DevTools: Reports missing required children
- WAVE: Flags ARIA structure issues
TL;DR (The Simple Version)
Your ARIA containers are missing required child elements. For example, if you have role="list", you need role="listitem" children inside it.
