Quick Reference
Element Code: AC-011
Issue: Invalid ARIA attribute names are being used
Impact: Invalid attributes are ignored, providing no accessibility benefit
Fix: Use only valid ARIA attribute names from the specification
Detection: axe DevTools, HTML validators
What Is This Issue?
Just like roles, ARIA attribute names must exactly match the specification. Typos or made-up attributes are ignored completely. Common errors include aria-labelled instead of aria-label, or aria-description instead of aria-describedby.
Common Mistakes
- aria-labelled (should be aria-label or aria-labelledby)
- aria-role (should just be role)
- aria-description (should be aria-describedby)
- aria-visible (not a valid attribute)
How to Fix This Issue
- Check Spelling: Verify attribute names exactly match specification
- Use Autocomplete: IDE extensions can suggest valid attributes
- Run Validators: Automated tools catch invalid attributes
TL;DR (The Simple Version)
You're using ARIA attributes that don't exist. Check for typos and verify attribute names match the specification exactly. Common mistake: "aria-labelled" should be "aria-label" or "aria-labelledby".
