title: Why No Line Break After Input In Bootstrap
body: <p>Here is the code that I'm using for a simple form.  I pretty much copied the entire form from the example on Bootstrap's website, and removed all controls except a text input and the submit button.</p>
  
  <pre><code>&lt;form&gt;
      &lt;fieldset&gt;
          &lt;legend&gt;About You&lt;/legend&gt;
          &lt;input class="input-medium" type="text" placeholder="First Name"&gt;
          &lt;button type="submit" class="btn"&gt;Get Started&lt;/button&gt;
      &lt;/fieldset&gt;
  &lt;/form&gt;
  </code></pre>
  
  <p>For some reason, the submit button doesn't drop to a new line when it comes right after an input.</p>

  <p>You'll see, if I just add the checkbox w/ label back from the example, the submit button drops to a new line as expected.</p>
  
  <pre><code>&lt;form&gt;
      &lt;fieldset&gt;
          &lt;legend&gt;About You&lt;/legend&gt;
          &lt;input class="input-medium" type="text" placeholder="First Name"&gt;
          &lt;label class="checkbox"&gt;
              &lt;input type="checkbox"&gt; Check me out
          &lt;/label&gt;
          &lt;button type="submit" class="btn"&gt;Get Started&lt;/button&gt;
      &lt;/fieldset&gt;
  &lt;/form&gt;
  </code></pre>

  <p>What am I doing wrong?  I'm using the latest bootstrap CSS and JS (2.3.2), loaded from BootstrapCDN.com.</p>
