animation-iteration-count 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-iteration-count CSS property sets the number of times an animation sequence should be played before stopping.

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

Try it

animation-iteration-count: 0;
animation-iteration-count: 2;
animation-iteration-count: 1.5;
<section class="flex-column" id="default-example">
  <div>Animation <span id="play-status"></span></div>
  <div id="example-element">Select a count to start!</div>
</section>
#example-element {
  align-items: center;
  background-color: #1766aa;
  border-radius: 50%;
  border: 5px solid #333333;
  color: white;
  display: flex;
  flex-direction: column;
  height: 150px;
  justify-content: center;
  margin: auto;
  margin-left: 0;
  width: 150px;
}

#play-status {
  font-weight: bold;
}

.animating {
  animation-name: slide;
  animation-duration: 3s;
  animation-timing-function: ease-in;
}

@keyframes slide {
  from {
    background-color: orange;
    color: black;
    margin-left: 0;
  }
  to {
    background-color: orange;
    color: black;
    margin-left: 80%;
  }
}
const el = document.getElementById("example-element");
const status = document.getElementById("play-status");

function update() {
  status.textContent = "delaying";
  el.className = "";
  window.requestAnimationFrame(() => {
    window.requestAnimationFrame(() => {
      el.className = "animating";
    });
  });
}

el.addEventListener("animationstart", () => {
  status.textContent = "playing";
});

el.addEventListener("animationend", () => {
  status.textContent = "finished";
});

const observer = new MutationObserver(() => {
  update();
});

observer.observe(el, {
  attributes: true,
  attributeFilter: ["style"],
});

update();

Syntax

css
/* Keyword value */
animation-iteration-count: infinite;

/* <number> values */
animation-iteration-count: 3;
animation-iteration-count: 2.4;

/* Multiple values */
animation-iteration-count: 2, 0, infinite;

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

The animation-iteration-count property is specified as one or more comma-separated values.

Values

infinite

The animation will repeat forever.

<number>

The number of times the animation will repeat; this is 1 by default. You may specify non-integer values to play part of an animation cycle: for example, 0.5 will play half of the animation cycle. Negative values are invalid.

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.

Note: When creating CSS scroll-driven animations, specifying an animation-iteration-count causes the animation to repeat that number of times over the course of the timeline's progression. If an animation-iteration-count is not provided, the animation will only occur once. infinite is a valid value for scroll-driven animations, but it results in an animation that doesn't work.

  animation-iteration-count: 10;
}

@keyframes rotate {
  0% {
    transform: rotate(0);
  }
  100% {
    transform: rotate(360deg);
  }
}
