        <h1>Navbar example</h1>
        <p>This example is a quick exercise to illustrate how the default,static and fixed to top navbar work. It includes the responsive CSS and HTML,so it also adapts to your viewport and device.</p>
        <p>To see the difference between static and fixed top navbars,just scroll.</p>

          <a class="btn btn-lg btn-priMary" href="../../components/#navbar" role="button">View navbar docs &raquo;</a>
