id attribute value must be unique
What is the problem?
The "duplicate-id" rule ensures that each id attribute value within an HTML document is unique.
Impacted Groups
Why is this important?
Duplicate id values can confuse screen readers and other assistive technologies. This can lead to incorrect information being conveyed to users or unexpected behavior, making it harder for them to understand and interact with the content.
How to solve this issue
To fix this, ensure that each id attribute value is unique within the document. This can be achieved by using a consistent naming convention for IDs or by generating unique IDs automatically. By ensuring unique IDs, you can improve the accessibility of your website for screen reader users.
