Providing a link, button, or other mechanism that reloads the page without any blinking content

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

This technique relates to all technologies.

This technique relates to Success Criterion 2.2.2: Pause, Stop, Hide (Sufficient).

Description

This is a general technique for allowing people who cannot use a page with blinking content to turn the blinking content off. Conformance Requirement 1 allows for conforming alternate pages to be used to meet conformance. This technique is an example of that approach applied to success criteria 2.2.2.

It is important that the page without blinking content contain all of the information that was on the page with blinking content.

Note

Removing the content that was blinking from the page would only be satisfactory if the blinking content was redundant with non blinking content in the original page.

This technique can be used in combination with a style switching technique to present a page that is a conforming alternate version for non-conforming content. Refer to C29: Using a style switcher to provide a conforming alternate version and Understanding Conforming Alternate Versions for more information.

Examples

  3. Check that the reloaded page has all the information and functionality of the original page.
