G68: Providing a short text alternative that describes the purpose of live audio-only and live video-only content


Applies to all technologies

This technique relates to:


This technique provides a short text alternative for Live audio-only and live video-only content. This text may be used in combination with a full text alternative for time-based media (for audio or video), or in combination with audio description (for video). Those alternatives, however, are not part of this technique. The purpose of this technique is to ensure that the user can determine what the non-text content is, even if they cannot access it. NOTE: Even if full alternatives are also available, it is important that users be able to identify the non-text content when they encounter it so that they are not confused, and so that they can associate it with the full alternative when they encounter it.


Example 1


Resources are for information purposes only, no endorsement implied.



  1. Remove, hide, or mask the non-text content.

  2. Display the short text alternative(s).

  3. Check that the purpose of the non-text content is clear, even if content is lost.

Expected Results

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.

Techniques are Informative

Techniques are informative—that means they are not required. The basis for determining conformance to WCAG 2.0 is the success criteria from the WCAG 2.0 standard—not the techniques. For important information about techniques, please see the Understanding Techniques for WCAG Success Criteria section of Understanding WCAG 2.0.
