         src="https://www.tutorialspoint.com/html5/foo.mp4" type="video/mp4"></video><br>
         <input type="button" onclick="getTrackDetails(1)" value="Too High (-)">
         <input type="button" onclick="getTrackDetails(2)" value="Too Low (+)">
         <div id="divDisplay"></div>
      </fieldset>
   </form>
   <script>
      var divDisplay = document.getElementById("divDisplay");
      var demo = document.getElementById("demo");
      function getTrackDetails(val) {
         if(val === 1){
            if(demo.volume < 0.2)
               demo.volume = 0.1;
               demo.volume -= 0.1;
               divDisplay.textContent = 'Volume: '+demo.volume;
            }
         else{
            demo.volume += 0.1;
            divDisplay.textContent = 'Volume: '+demo.volume;
         }
      }
   </script>
</body>
</html>
