<meta name="assert" content="Check that animation shorthand applies to the ::after pseudo element
                             and accepts time values for animation-duration and animation-delay
                             in order.">
<style>
  div::after {
    animation: 10s 2s sample;

    background-color: blue;
    content: "Filler Text";
    display: block;
    height: 100px;
    width: 100px;
    position: relative;
  }

  @keyframes sample {
    from {
      left: 150px;
    }
    to {
      left: 0px;
    }
  }
</style>
<body>
  <p>
    Test passes if there is a filled blue square with 'Filler Text',
    which starts staying left about 2 seconds, and then moves from right to left
    and lasts for a span of 10 seconds.
