What this rule checks

This rule checks whether meaningful non-text content exposes an accessible text alternative that explains its purpose or information.

Why it matters

Screen-reader users and other assistive technology users rely on accessible names or descriptions to understand images, icons, and other non-text elements.

Common failure patterns

• meaningful images with no alt text
• icon-only controls with no accessible name
• charts or visual indicators with no text alternative

Remediation guidance

• add accurate alt text for meaningful content
• mark decorative content as decorative so it is ignored correctly
• ensure icon-only controls expose an accessible name through the appropriate attribute or label
