Important Information about Techniques

See Understanding Techniques for WCAG Success Criteria for important information about the usage of these informative techniques and how they relate to the normative WCAG 2.1 success criteria. The Applicability section explains the scope of the technique, and the presence of techniques for a specific technology does not imply that the technology can be used in all situations to create content that meets WCAG 2.1.

Applicability

Content that automatically updates itself.

This technique relates to Success Criterion 2.2.4: Interruptions (Sufficient).

Description

The objective of this technique is to ensure that users can postpone automatic updates of content, or other non-emergency interruptions. This can be accomplished either through a preference or by alerting users of an imminent update and allowing them to suppress it. If a preference is provided, automatic content update can be disabled by default and users can specify the frequency of automatic content updates if they choose to enable the setting.

Examples

Tests

Procedure

  1. Find pages with content that automatically updates.
  2. For each automatic update, look for a mechanism to adjust the timing of the updates.
  3. Check that automatic updating is disabled by default or that the user is warned before an automatic update occurs and allowed to suppress it.

Expected Results

  • #3 is true.
