I want to align li values right most of the screen. but it does not appear.

Codepan: http://codepen.io/

 <div class="navbar navbar-default navbar-fixed-top" role="navigation">
        <div class="container">   

    <ul class="nav navbar-nav navbar-right">
            <li><a href="../navbar-static-top/">Static top</a></li>
            <li><a href="../navbar-fixed-top/">Fixed top</a></li>
          </ul>

        </div>
      </div>

text-align:right; or align="right" does not help
