I wanted to hide the Poll, Calendar and Question links in the navigation bar.  However there is no id tag for calendar :

 

<a id="confluence-questions-link" href="/questions?src=header" class=" aui-nav-imagelink" title="">
<span>Questions</span>
</a>
</li>
<li>
<a id="polls-link" href="/polls/listpolls.action" class=" aui-nav-imagelink" title="Voir vos sondages">
<span>Sondages</span>
</a>
</li>
<li>
<a href="/calendar/mycalendar.action" class=" aui-nav-imagelink" title="Calendriers">
<span>Calendriers</span>
</a>
</li>

 

It would be great to have an id to be able to apply some CSS on this button only (e.g. display:none).
