See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.0 success criteria. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.0.
Technologies that support Accessible Rich Internet Applications (WAI-ARIA).
This technique relates to:
See User Agent Support Notes for ARIA14. Also see WAI-ARIA Technology Notes.
For sighted users, the context and visual appearance of an element can provide sufficient cues to determine the purpose. An example is the 'X' often used in the top right corner of pop-up divs (light boxes) to indicate the control for closing the div.
In some situations, elements can be given the attribute aria-label
to provide an accessible name for situations when there is no visible label due to a chosen design approach or layout but the context and visual appearance of the control make its purpose clear.
In other situations, elements can be given the attribute aria-label
to provide an accessible name when the native HTML labeling element is not supported by the control - for example, when a div
set to contentEditable
is used instead of native form elements such as input type="text"
or textarea
in order to provide a richer text editing experience.
On a page, a link displays a pop-up box (a div) with additional information. The 'close' element is implemented as a button containing merely the letter 'x'. The property aria-label="close"
is used to provide an accessible name to the button.
<div id="box">
This is a pop-up box.
<button aria-label="Close" onclick="document.getElementById('box').style.display='none';" class="close-button">X</button>
</div>
Working example: Close button example.
<div role="group" aria-labelledby="groupLabel">
<span id="groupLabel>Work Phone</span>
+<input type="number" aria-label="country code">
<input type="number" aria-label="area code">
<input type="number" aria-label="subscriber number">
</div>

For elements that use aria-label
:
Check that the value of the aria-label
attribute properly describes the purpose of an element where user input is required
#1 is true.
If this is a sufficient technique for a success criterion, failing this test procedure does not necessarily mean that the success criterion has not been satisfied in some other way, only that this technique has not been successfully implemented and can not be used to claim conformance.
