   Touch inside the box. On a touch enabled browser, you will get the number
   of detected touch events. If the box is red, your browser does not support
   touch events.
  <script>
    var box = document.getElementById("box");
    box.addEventListener("touchstart", function(evt) {
        box.innerHTML = evt.touches.length;
        evt.preventDefault();
    });    
    if (!(typeof box.ontouchstart != 'undefined')) { 
        box.style.backgroundColor = "red";
    }
