<blink> elements are deprecated and must not be used
How to Fix the Problem
An example of a code snippet you should remove from an HTML file:
<p><blink>Moving Sale Thursday!</blink></p>
An example of a code snippet you should remove from a CSS file:
A number of modern browsers do not support blinking text. It is entirely
possible that you will have the
blink element in an HTML file,
but this won’t produce blinking text on the web page. For this reason, don’t
rely on the visual rendering of an HTML document to determine whether there
blink tags in it; be sure to check the actual file
To fix both of the above code examples, remove the
text-decoration: blink; from your CSS. Replace this markup
to make the text stand out in some other way.
Why it Matters
As the name suggests,
blink tags cause content to flash. Though
you may like the effect, blinking text can be difficult to read, and blinking
objects (links, buttons, etc.) can be difficult to activate, especially for
users with imprecise or limited dexterity.
It can be very difficult for people with visual and cognitive disabilities to
see and understand text that blinks. Blinking text be distracting, especially
for users with cognitive disabilities. It can also be difficult for some
individuals to comprehend. For these reasons, the
should never be used.
This rule requires that no
blink elements are present. Flashing
text can be difficult to read and blinking objects can be difficult to
activate. The associated automated check finds the presence of all
blink elements so that they can be removed.
The Algorithm (in simple terms)
Checks to make sure that the
blink element is never used.
