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.
When any content on the page starts moving or updating automatically, on the same page as other content, check that there is a way to either:
- pause and resume it
- stop it
- hide it
The user must still be able to read or interact with other content on the page. For example, if a video can only be paused by hovering over it or focusing on it, this fails the criterion because the user is unable to scroll to and read the rest of the page.
There does not need to be a way to pause, stop or hide content when either:
- moving content moves for no longer than 5 seconds
- automatically-updating content has a way to change how often it updates
- it’s essential that content moves or updates by itself
An example of an essential animation could be a loading indicator which tells a user that a page is loading. Without this animation, they might think that the page was frozen.
When pausing live content, it does not need to resume from the same point. For example, with live streaming videos or real-time updates on stock market values, it’s fine to resume from the current live position.
- Animations should not start automatically.
- The way to pause, stop or hide should be clear and easy to find.
- Paused content should stay visible. For example, when you pause a ticker, you should still be able to read what it is saying in its paused state.
- Stopped or hidden content should be able to be restarted from the beginning or unhidden.
- Avoid using unnecessary animations and use text instead.
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.
