Inappropriate Id Attributes Check

Description

The “Inappropriate Id Attributes Check” evaluates whether any two elements have the same id attribute.

Example outcome

I found 1 repeated id attribute on this webpage.

Impact

• Visual Impairments: Screen readers may misread or skip content.
• Motor Impairments: Skip links or modal focus traps may not behave as expected.
• Cognitive Disabilities: Errors in structure cause confusion or misinterpretation.

Fixes

To address inappropriately repeated id attributes:

1. Locate the different elements with the same id.
2. Change them in order to ensure that each element has a unique id.
