HTML and XHTML.
This failure relates to:
The blink element is not supported by Internet Explorer 6 on Windows. It is supported in Netscape/Mozilla family of user agents and Opera on Windows.
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.
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>
Examine code for the presence of the blink
element.
If #1 is true, the content fails the Success Criterion.
