  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>@keyframes slideDown {
      0% {
        transform: translateY(-100%);
      }
      100% {
        transform: translateY(0%);
      }  
    }
    
    @-webkit-keyframes slideDown {
      0% {
        -webkit-transform: translateY(-100%);

      100% {
        -webkit-transform: translateY(0%);
