Simple CSS3 animation not running in IE 11
<p>I have an example of a basic circle loader animation that will not start in IE 11 but runs smooth it just about every other browser</p>

<p>Code:</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-css lang-css prettyprint-override"><code>.circular-still {
  height: 150px;
  -webkit-transform-origin: center center;
  transform-origin: center center;
  width: 150px;
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  margin: auto;
}
.path {
  -webkit-animation: dash 1.5s ease-in-out infinite;
  animation: dash 1.5s ease-in-out infinite;
  stroke: #c0c0c0;
  stroke-linecap: round;
  stroke-dasharray: 89, 200;
  stroke-dashoffset: -124px;
}
@-webkit-keyframes dash {
  0% {
    stroke-dasharray: 1, 200;
    stroke-dashoffset: 0;
  }
  50% {
    stroke-dasharray: 89, 200;
    stroke-dashoffset: -35px;
  }
  100% {
    stroke-dasharray: 89, 200;
    stroke-dashoffset: -124px;
  }
}
@keyframes dash {
  0% {
    stroke-dasharray: 1, 200;
    stroke-dashoffset: 0;
  }
  50% {
    stroke-dasharray: 89, 200;
    stroke-dashoffset: -35px;
  }
  100% {
    stroke-dasharray: 89, 200;
    stroke-dashoffset: -124px;
  }
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div id="loader" style="display: block;"&gt;
  &lt;svg class="circular-still" viewBox="25 25 50 50"&gt;
    &lt;circle class="path" cx="50" cy="50" r="20" fill="none" stroke-width="4" stroke-miterlimit="5" /&gt;
  &lt;/svg&gt;
&lt;/div&gt;</code></pre>
</div>
</div>
</p>

<p>Below is an example if opened in any browser but IE 11 you should get an animated circle but just a dot in IE11 </p>
