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 2.0 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 2.0.
HTML and XHTML
This failure relates to:
The blink element, while not part of the official HTML or XHTML
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.
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.
Example Code:
<p>My Great Product <blink>Sale! $44,995!</blink></p>

Examine code for the presence of the blink
element.
If #1 is true, the content fails the Success Criterion.
