How to display a 5secend video before page load in html?

I have a simple Html5 landing page and i want to show a 5secend video before the main page. it could be a popup or anything all i want is to display the video without any borders,playback buttons etc. and then load the main page.

Greetings! this is what i tried

<script>
  function openColorBox(){
    $.colorbox({iframe:true, width:"80%", height:"80%", href: "http://as2.asset.aparat.com/aparat-video/325cc0361862066dc06e8fb1fc7ec8a77684093-240p__39060.mp4"});
  }


  setTimeout(openColorBox, -5000);
  $.colorbox({ overlayClose: true });


</script>

Solution

A simple page which loads the video in bootstrap modal window. Hope this gives you a start!

<!DOCTYPE html>
    <html lang="en">

        <!-- Modal -->
        <div class="modal fade" id="myModal" role="dialog">

            </div>
        </div>
    </body>

    </html>
    <script>
    $("#myModal").modal()
    $(".container").hide();
    document.getElementById('myVideo').addEventListener('ended', closeModal, false);

    function closeModal() {
        $(".container").show();
        $('#myModal').modal('hide');
    }
    </script>
