<blink> elements are deprecated and must not be used

Avoid using animation and blinking that cannot be controlled by the user.

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 blink element should never be used.

Fixing the problem

Remove all blink elements.

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:

h1 {
    text-decoration: blink;

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 are blink tags in it; be sure to check the actual file contents.

To fix both of the above code examples, remove the blink element and/or text-decoration: blink; from your CSS. Replace this markup to make the text stand out in some other way.
