WCAG 4.1.1 · Level A
Duplicate Id Aria
- What is broken
- The same id appears more than once where ARIA references it, so the reference resolves to the wrong element.
- 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
- Make every id referenced by ARIA unique within the page.
