title: Bootstrap : Add a button link in the bottom right corner of a thumbnail
body: <p>I want to do something like that : </p>
  
  <p><img src="https://i.stack.imgur.com/5wpwo.png" alt="enter image description here"></p>
  
  <p>For now, I'm using margin but I'm sure there is some "clean" method to do that... :

  <pre><code>&lt;ul class="media-grid"&gt;
    &lt;li&gt;
      &lt;a href="#"&gt;
          &lt;img class="thumbnail" src="http://placehold.it/140x90" alt=""/&gt;
      &lt;/a&gt;
      &lt;a href="#" class="btn" style="margin-left:-23px;margin-top:67px;"&gt;+&lt;/a&gt;
    &lt;/li&gt; 
    &lt;li&gt;
      &lt;a href="#"&gt;
          &lt;img class="thumbnail" src="http://placehold.it/140x90" alt=""/&gt;
      &lt;/a&gt;
      &lt;a href="#" class="btn" style="margin-left:-23px;margin-top:67px;"&gt;+&lt;/a&gt;
    &lt;/li&gt;
