ARIA attribute is defined in WAI-ARIA
1.3.1 Info and Relationships
This document provides information about the related accessibility checks:
ARIA attribute is defined in WAI-ARIA.
ARIA attributes may only be used if they are included in the ARIA 1.2 standard.
If the code contains attributes that start with aria- and they are not defined in the ARIA standard, it indicates that the website developer may have made a typographical or coding error. As a result, the intended accessibility features may not work as expected
This check affects the following users who have:
Visual impairments: Who access the site contents with a screen reader or screen magnification software.
Mobility impairments: Who navigate the page with speech recognition software.
Bridgit is a blind mother to a five-year-old girl and an 11-year-old boy:
"There are some things that are just tricky, and then there are things that do not work at all. One thing that often does not work is those drop-downs where you have to search for something. You know, where you type in text and then a list of suggestions pops up, and you have to choose from that list instead of just typing what you want. This happens a lot when I am booking flights. The field where I have to choose which airport I am flying from and to. Sometimes I can type in the text, and the screen reader will tell me there are, say, 3 or 10 results on the list. But I cannot see or select anything from that list. I just get stuck and cannot move forward."
This section gives some examples of the issue.
Example: Checkbox with wrong ARIA attribute
A checkbox is coded using a <div> element, with the role and state of the checkbox added through ARIA attributes. Unfortunately, the attribute that is intended to indicate the state of the checkbox is not a valid ARIA attribute because aria-not-checked is not part of the WAI-ARIA standard.
Web Governance<div role="checkbox" aria-not-checked="false">Accept terms and conditions.</div>aria-not-checked.Example: Checkbox with correct ARIA attribute
A checkbox is coded with a <div> element, with the role and state of the checkbox added through ARIA attributes.
<div role="checkbox" aria-checked="true">Accept terms and conditions.</div>The Web Governance platform flags instances of attributes that start with aria- but are not defined in the ARIA standard. You need to correct these attributes so that your code only uses valid ARIA attributes as defined in the WAI-ARIA standard
