Use a css class for the animation and add the class to div when button clicked. (use @keyframes to define css animations.)

A full example without using Jquery:

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
  <meta charset="utf-8" />
  <title>CSS Animations</title>

  <style>
    /* <![CDATA[ */
    div {
      height: 2em;
      width: 50%;
      border: 1px solid black;
      background-color: black;
      color: yellow;
    }

    .animate {
      animation-name: slide-right;
      animation-duration: 2s;
      /* Preserve the effect of the animation at ending */
      animation-fill-mode: forwards;
    }

    @keyframes slide-right {

      from {
        margin-left: 0px;
      }

      50% {
        margin-left: 110px;
        opacity: 0.5;
      }

      to {
        margin-left: 200px;
        opacity: 0.2;
      }
    }

    /* ]]> */
  </style>

  <script>
    /* <![CDATA[ */

    function DoAnimation() {
      var targetElement = document.getElementById("target");
      targetElement.className = "animate";
    }
    /* ]]> */
  </script>
</head>
<body>
  <h1>CSS Animations</h1>
  <div id="target">Super div</div>
  <button onclick="DoAnimation();">Go</button>
</body>
</html>

Remove the -webkit-animation and animation definitions from #firstChild and instead create an "anim" class definition:

#first-child {
    height: 200px;
    width: 200px;
    background: white;
    border-radius: 0%;
    margin-top: 150px;
    margin-bottom: 0px;
    margin-left: 500px;
    margin-right: 0px;
}
.anim{
    -webkit-animation: myfirst 1s;
    animation: myfirst 1s;
}

Then when you want to trigger the animation simply add the .anim class to your element with jQUery:

$("#first-child").addClass("anim");
