jssor slider missing content in IE but ok in Chrome

I have created a simple slider using jssor, and it works fine in Chrome. However, when I view the same slide in IE 11, the text is missing (but the background image is present).

Can someone tell me what is wrong with this code - why won't the text show up in IE 11? When I visit the jssor.com website with IE the demos work fine.

            <div style="color:white;font-size:200%;">THIS TEXT DOES NOT SHOW UP IN IE 11</div>
          </div>
        </div>
      </div>
    </div>
    <script>
      jQuery(document).ready(function ($) {
        options = { $AutoPlay: true, $FillMode: 1, $AutoPlayInterval: 8000 };   
        valueobject = new $JssorSlider$('panel_topslider', options);
      });
    </script>
  </body>

Solution

Please specify position, top and left for the element.

<div style="position: absolute; top: 0px; left: 0px; color:white;font-size:200%;">THIS TEXT WILL SHOW UP IN IE 11</div>
