2.2.2
For moving, blinking, scrolling, or auto-updating information, all of the following are true:
Moving, blinking, scrolling: For any moving, blinking or scrolling information that (1) starts automatically, (2) lasts more than five seconds, and (3) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it unless the movement, blinking, or scrolling is part of an activity where it is essential; and
Auto-updating: For any auto-updating information that (1) starts automatically and (2) is presented in parallel with other content, there is a mechanism for the user to pause, stop, or hide it or to control the frequency of the update unless the auto-updating is part of an activity where it is essential.
If any content on the page is moving (against static content).
Look at the page. If there is moving content, check:
- it stops moving after 5 seconds
- if moving content does not stop after 5 seconds, there is a mechanism that stops, pauses or hides it or loads an alternative page without it
- any mechanisms to stop, pause or hide moving content work
- the movement can be started again after being stopped or paused
- you can control the frequency of the update
- any mechanism to stop, pause or hide moving content do not rely on hovering or focusing alone
Although you need to be able to pause live stuff, it does not need to resume where it had paused, for example live streaming videos, or real-time updates on stock market values.
Animated loading indicators where you cannot interact with anything on the page can be considered essential, in the case where not having the animation might lead users to think the page was broken or frozen. In this case, there does not need to be a mechanism to stop, pause or hide the animation.
Check:
- the mechanism is clear and easy to find
- unpausing resumes the movement from the moment it was paused
- stopping and starting restarts it from the beginning
- all content is still available when moving content has stopped moving - for example, when you pause a ticker, you should still be able to read what it is saying in its paused state
If this Success Criteria fails it means the whole page fails because there is something interfering with the other content in a way which makes it inaccessible to some people. That includes if third-party content causes this to fail, even if it is otherwise excluded from the audit. See Non-Interference.
