  &lt;!-- Modal --&gt;
  &lt;div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"&gt;
  &lt;div class="modal-header"&gt;
  &lt;button type="button" class="close" data-dismiss="modal" aria-hidden="true"&gt;×&lt;/button&gt;

  &lt;div class="modal-body"&gt;
  &lt;p&gt;One fine body…&lt;/p&gt;
