animation-iteration-count

Defines how many times an animation runs.

animation-iteration-count: <value>;

where <value> can be one of the following:

• Number value: 3, 300
• inifinite will run animation on endless loop

Note: providing one value will apply to all animation-name values. Additional comma separated values will apply correspondingly.

Run animation fadeoutfadein two times:

div {
  height: 200px;
  width: 200px;
  background-color: blue;
  animation-duration: 2s;
  animation-name: fadeoutfadein;
  animation-iteration-count: 2;
}

@keyframes fadeoutfadein {
  0% {
    background-color: blue;
  }
  50% {
    background-color: white;
  }
  100% {
    background-color: blue;
  }
}

Run animation fadeoutfadein two times and slideleft one time:

div {
  height: 200px;
  width: 200px;
  background-color: blue;
  animation-duration: 4s, 4000ms;
  animation-name: fadeoutfadein, slideleft;
  animation-iteration-count: 1, 2;
}

@keyframes fadeoutfadein {
  0% {
    background-color: blue;
  }
  50% {
    background-color: white;
  }
  100% {
    background-color: blue;
  }
}

@keyframes slideleft {
  from {
    margin-left: 100%;
  }

  to {
    margin-left: 0%;
  }
}
