title: Why won't my button center in Bootstrap
body: <p>I've tried a few options. What is the correct way to center a button in a div. Using CSS? Bootstrap?</p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;div class"col-md-12 text-center"&gt;
    &lt;button type="button" class="btn btn-primary"&gt;Generate a Quote&lt;/button&gt;
  &lt;/div&gt;
  </code></pre>
