title: Bootstrap: How to place button next to input-group
body: <p>I can't work out (conforming to "proper bootstrap") how to get a button to sit next to an input-group within a div.</p>
  
  <p>They need to be center aligned.</p>
  
  <p>This is what I want it to look like...</p>

  <p>Here is my current code.</p>
  
  <pre><code>&lt;div&gt;
      &lt;div&gt;
          &lt;button type="button" class="btn"&gt;Delete&lt;/button&gt;
      &lt;/div&gt;
      &lt;div&gt;
          &lt;div class="input-group"&gt;
              &lt;input type="text" class="form-control" value="1" /&gt;
              &lt;span class="input-group-addon"&gt;Update&lt;/span&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
