<blink>: The Blinking Text element

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The <blink> HTML element is a non-standard element which causes the enclosed text to flash slowly.

Warning: Do not use this element as it is obsolete and is bad design practice. Blinking text is frowned upon by several accessibility standards and the CSS specification allows browsers to ignore the <blink> element.

DOM interface

This element is unsupported and thus implements the HTMLUnknownElement interface.


<blink>Why would somebody use this?</blink>

Result (toned down!)

Text "why would somebody use this" flashing on and off.

CSS polyfill

  animation: 2s linear infinite condemned_blink_effect;

@keyframes condemned_blink_effect {
  0% {
    visibility: hidden;
  50% {
    visibility: hidden;
  100% {
    visibility: visible;
