8.13 Level A − WCAG 2.0 Success Criterion 2.2.2 − Pause, Stop, Hide

For content that moves automatically for more than five seconds or is updated automatically, there needs to be a way to stop this movement and stop the webpage from updating, blinking or scrolling.

Before Rectification

A webpage sample containing an information ticker.

In the example above, the webpage is designed to update automatically as content changes, which can be very frustrating for people using screen readers.

After Rectification

A webpage sample containing an information ticker with controls that allow automatic updates to be turned ON or OFF.

By providing a function to turn off the auto updating, the webpage will be much easier for persons with disabilities to use.
