An “aria-disabled” attribute whose value is “true” should not be specified on an “a” element that has an “href” attribute.

An a element with both an href attribute and aria-disabled="true" is invalid; either remove aria-disabled or the href attribute.

The aria-disabled attribute is used for interactive elements to indicate that the element is perceivable as disabled by assistive technologies. However, using aria-disabled="true" in combination with an href attribute on an a element is not valid, because the link remains actionable for both user agents and assistive devices. Instead, if a link should appear disabled, you should remove the href attribute, use CSS for styling, and optionally use aria-disabled="true". If you need the element to always act as a link, avoid aria-disabled and control user access through application logic.

Incorrect:

<a href="page.html" aria-disabled="true">Visit Page</a>

Correct—Option 1: Remove aria-disabled, keep link active

<a href="page.html">Visit Page</a>

Correct—Option 2: Remove href, use aria-disabled, for non-actionable item

<a aria-disabled="true" tabindex="-1" style="pointer-events: none; color: gray;">Visit Page</a>

In the second correct example, setting tabindex="-1" prevents keyboard navigation, and pointer-events: none; makes the link unclickable, while aria-disabled="true" makes the disabled state accessible.
