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

/* 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.

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.

animation-iteration-count = 
  <single-animation-iteration-count>#  

<single-animation-iteration-count> = 
  infinite        |
  <number [0,∞]>  

This animation will run 10 times.

HTML

<div class="box"></div>

CSS

.box {
  background-color: rebeccapurple;
  border-radius: 10px;
  width: 100px;
  height: 100px;
}

.box:hover {
  animation-name: rotate;
  animation-duration: 0.7s;
  animation-iteration-count: 10;
}

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

Result

Hover over the rectangle to start the animation.
