Checks that IDs used in ARIA attributes are unique

| | |
|---|---|
| **Rule ID** | `a11y/duplicate-id-aria` |
| **Category** | [Accessibility](/rules/a11y) |
| **Scope** | Per-page |
| **Severity** | error |
| **Weight** | 8/10 |

## Solution

IDs referenced by ARIA attributes (aria-labelledby, aria-describedby, aria-controls, etc.) must be unique on the page. Duplicate IDs cause assistive technology to potentially reference the wrong element. Rename duplicate IDs to be unique.
