// Use when reviewing rendered HTML, interactive components, or design-system patterns related to Ensure ARIA attributes are valid. Check native semantics first, then inspect keyboard behavior, focus flow, accessible names, and screen-reader output where relevant.
Ensure ARIA attributes are valid
Invalid ARIA attributes are ignored by browsers and screen readers, potentially leaving users with disabilities unable to navigate or understand the interface.
Quick Reference
- Use only valid, standard-defined ARIA attributes
- Avoid misspelled or non-existent aria-* properties
- Ensure screen readers correctly interpret element roles and states
Check
Identify any invalid or misspelled ARIA attributes on HTML elements.
Fix
Replace invalid ARIA attributes with their correct names as defined in the WAI-ARIA specification.
Explain
Explain how valid ARIA attributes enable assistive technologies to communicate element state and behavior to users.
Code Review
Review the rendered markup and interactive states that affect Ensure ARIA attributes are valid. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.
