 <link rel="stylesheet"
          href="../../../../_static/bootstrap/docs/assets/css/bootstrap.css"
          type="text/css" />

 <h1>Lightning talks day 3 - Djangocon.eu<a class="headerlink" href="#lightning-talks-day-3-djangocon-eu" title="Permalink to this headline">¶</a></h1>

then in the css:

 .headerlink {
   visibility: hidden;
 }
 h1:hover .headerlink,
 h2:hover .headerlink,
 h3:hover .headerlink,
 h4:hover .headerlink,
 h5:hover .headerlink,
