Technique F47:Failure of Success Criterion 2.2.2 due to using the blink element
About this Technique
This technique relates to 2.2.2: Pause, Stop, Hide (Failure).
This failure applies to HTML.
Description
The blink element, while not part of the official HTML specification, is supported by many user agents. It causes any text inside the element to blink at a predetermined rate. This cannot be interrupted by the user, nor can it be disabled as a preference. The blinking continues as long as the page is displayed. Therefore, content that uses blink fails the Success Criterion because blinking can continue for more than three seconds.
Examples
Example 1
A product list page uses the blink element to draw attention to sale prices. This fails the Success Criterion because users cannot control the blink.
<p>My Great Product <blink>Sale! $44,995!</blink></p>Related Resources
