    <h1>Step 1: check availability of the Geolocation API</h1>
    <p>As a first step, let us just check whether the HTML5 Geolocation API is
      present in this browser or not.</p>

    <div id="geo"></div>
    </body>

  <script>
    document.getElementById('geo').innerHTML = navigator.geolocation ?
      'Geolocation API is available' :
      'Geolocation API is not available';
    </script>
  </html>
