body: <p>How to make an alert take the width of its content?</p>
  
  <p>This div will take all the available space while I would like it to be only as long as my text.</p>
  
  <pre><code>&lt;div class="alert alert-info"&gt;
      &lt;span class="glyphicon icon-info"&gt;&lt;/span&gt; My text.
  &lt;/div&gt;
  </code></pre>
