This technique relates to all technologies.
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.
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 Using a style switcher to provide a conforming alternate version and Understanding Conforming Alternate Versions for more information.
