      padding: 2px;
   form {
      margin: 0 auto;
      text-align: center;
   input[type="button"] {
      border-radius: 10px;
<video id="wordPressIntro" width="320" height="50" controls><source src="" type="video/mp4"></video><br>
<input type="button" onclick="getTrackDetails()" value="Video Not Visible">
<div id="divDisplay"></div>
   var divDisplay = document.getElementById("divDisplay");
   var wordPressIntro = document.getElementById("wordPressIntro");
