Cascading Style Sheets.
This failure relates to:
The blink value of the text-decoration property
is not supported by Internet Explorer. It is supported in
Netscape/Mozilla family browsers. Not tested in others (e.g., Safari,
Opera).
CSS defines the blink value for the text-decoration
property. When used, it causes any text in elements with this property to
blink at a predetermined rate. This cannot be interrupted by the user, nor
can it be disabled as a user agent preference. The blinking continues as
long as the page is displayed. Therefore, content that uses
text-decoration:blink fails the Success Criterion because
blinking can continue for more than three seconds.
A product list page uses the text-decoration:blink style
on an element to draw attention to sale prices. This fails the
Success Criterion because users cannot control the blink.
Example Code:
<p>My Great Product <span style="text-decoration:blink">Sale! $44,995!</span></p>
Resources are for information purposes only, no endorsement implied.
Examine inline styles, internal stylesheets, and external
stylesheets for the text-decoration property with a
value of "blink".
If the property is used, determine if the ID, class, or element identified by selectors on which this property is defined are used in the document.
If step #1 and step #2 are true, the content fails the success criterion.
Techniques are informative—that means they are not required. The basis for determining conformance to WCAG 2.0 is the success criteria from the WCAG 2.0 standard—not the techniques.
