animation-name CSS property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2015.

The animation-name CSS property specifies the names of one or more @keyframes at-rules that describe the animation to apply to an element. Multiple @keyframes at-rules are specified as a comma-separated list of names. If the specified name does not match any @keyframes at-rule, no properties are animated.

It is often convenient to use the shorthand property animation to set all animation properties at once.

Try it

animation-name: none;
animation-name: slide;
animation-name: bounce;
<section class="flex-column" id="default-example">
  <div class="animating" id="example-element"></div>
</section>
#example-element {
  animation-direction: alternate;
  animation-duration: 1s;
  animation-iteration-count: infinite;
  animation-timing-function: ease-in;
  background-color: #1766aa;
  border-radius: 50%;
  border: 5px solid #333333;
  color: white;
  height: 150px;
  margin: auto;
  margin-left: 0;
  width: 150px;
}

@keyframes slide {
  from {
    background-color: orange;
    color: black;
    margin-left: 0;
  }
  to {
    background-color: orange;
    color: black;
    margin-left: 80%;
  }
}

@keyframes bounce {
  from {
    background-color: orange;
    color: black;
    margin-top: 0;
  }
  to {
    background-color: orange;
    color: black;
    margin-top: 40%;
  }
}

Syntax

css
/* No animation */
animation-name: none;

/* Single animation */
animation-name: test_05;
animation-name: -specific;
animation-name: "sliding-vertically";

/* Multiple animations */
animation-name: test1, animation4;
animation-name:
  none,
  -moz-specific,
  sliding;

/* Global values */
animation-name: inherit;
animation-name: initial;
animation-name: revert;
animation-name: revert-layer;
animation-name: unset;

Values

none

A special keyword denoting no keyframes. It can be used to deactivate an animation without changing the ordering of the other identifiers, or to deactivate animations coming from the cascade.

<custom-ident>

An unquoted name identifying the animation. This identifier is composed of a combination of case-sensitive letters a to z, numbers 0 to 9, underscores (_), and/or dashes (-). The first non-dash character must be a letter. Also, two dashes are forbidden at the beginning of the identifier. Furthermore, the identifier can't be none, unset, initial, or inherit.

<string>

A series of characters following the same rules as custom identifiers, as described above, except that they are surrounded by either double (") or single (') quotes. If using a quoted string for both the animation-name and the corresponding @keyframes at-rule name, none, global keywords, and names starting with an underscore or double dashes are valid, though not recommended.

Note: When you specify multiple comma-separated values on an animation-* property, they are applied to the animations in the order in which the animation-names appear. For situations where the number of animations and animation-* property values do not match, see Setting multiple animation property values.
