Bootstrap3: Tooltip support. NOTE: this requires the use of javascript -- calling the tooltip(); method

gistfile1.txt

<script>
(function(){
    $("#contactForm input[type=submit]").tooltip();

  //alternative is to set delay in code with more options:
     $("#contactForm input[type=submit]").tooltip(
       {
         delay:{
           show: 500,
           hide: 0
         }
       }); 
  })();
</script>

//NOTE IF USEING the 2nd approach, remove the declarative data-delay from the markup

                  <!--submit button-->
                  <input type="submit" value="Submit" class="btn btn-success btn-md"
                    data-toggle="tooltip" title="Press Here" data-placement="left" data-delay="500"/>
