WCAG 4.1.2 · Level A
Aria Valid Attr Value
- What is broken
- An ARIA attribute has an invalid value — most often a reference to an element id that does not exist.
- Who it affects
- Assistive technology is handed contradictory information about the control, so it may be announced wrongly or skipped entirely.
- How to fix it
- Give each ARIA attribute a valid value, and check that referenced ids are present on the page.
