10.2.18: Pause, stop, hide

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.

NOTE 1: For requirements related to flickering or flashing content, refer to WCAG 2.0 Guideline 2.3.

NOTE 2: This success criteria is applicable to all content in the document (whether or not there is an alternate accessible version of the document) since any part of a document that does not meet this success criterion can interfere with a user's ability to use the whole document (including a link to the alternate version).

NOTE 3: Content that is updated periodically by software or that is streamed to the user agent is not required to preserve or present information that is generated or received between the initiation of the pause and resuming presentation, as this may not be technically possible, and in many situations could be misleading to do so.

NOTE 4: An animation that occurs as part of a preload phase or similar situation can be considered essential if interaction cannot occur during that phase for all users and if not indicating progress could confuse users or cause them to think that content was frozen or broken.

NOTE 5: This is to be applied to all content. Any content, whether informative or decorative, that is updated automatically, blinks, or moves may create an accessibility barrier.

NOTE 6: This success criterion is identical to the WCAG 2.0 Success Criterion 2.2.2 Pause, Stop, Hide replacing "page" and "Web page" with "document", removing "See Conformance Requirement 5: Non-Interference" in note 2 of the success criterion, with the words "WCAG 2.0" added before the word "Guideline" in note 1 above and with note 2 above re-drafted to avoid the use of the word "must".
