<blink>: The Blinking Text element (obsolete) - HTML: HyperText Markup Language 编辑

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.

Obsolete

This feature is obsolete. Although it may still work in some browsers, its use is discouraged since it could be removed at any time. Try to avoid using it.

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

Do not use this element as it is obsolete and is bad design practice.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.

Example

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

Specifications

This element is non-standard and not part of any specification. If you don't believe us, see for yourself in the HTML spec.

CSS polyfill

If you really do need a polyfill, then you can use the following CSS polyfill. Works in IE10+.

blink {
  -webkit-animation: 2s linear infinite condemned_blink_effect; /* for Safari 4.0 - 8.0 */
  animation: 2s linear infinite condemned_blink_effect;
}

/* for Safari 4.0 - 8.0 */
@-webkit-keyframes condemned_blink_effect {
  0% {
    visibility: hidden;
  }
  50% {
    visibility: hidden;
  }
  100% {
    visibility: visible;
  }
}

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