G4: Allowing the content to be paused and restarted from where it was paused


Any technology that includes moving or scrolling content.

This technique relates to:


The objective of this technique is to provide a way to pause movement or scrolling of content. If the user needs to pause the movement, to reduce distraction or to have time to read it, they can do so, and then restart it as needed. This mechanism can be provided either through interactive controls that conform to WCAG or through keyboard shortcuts. If keyboard shortcuts are used, they are documented.




On a page with moving or scrolling content,

  1. Use the mechanism provided in the Web page or by the user agent to pause the moving or scrolling content.

  2. Check that the moving or scrolling has stopped and does not restart by itself.

  3. Use the mechanism provided to restart the moving content.

  4. Check that the movement or scrolling has resumed from the point where it was stopped.

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.
