title: fieldset width 100% of parent
body: <p>I need to have a scrollable div inside a fieldset. My problem is that a fieldset expands to it's contents width instead of staying withing its parent.</p>
  
  <pre><code>&lt;div class="section"&gt;
      &lt;fieldset&gt;
          &lt;div class="list"&gt;
          &lt;/div&gt;
      &lt;/fieldset&gt;
  &lt;/div&gt;
  </code></pre>

  <p>The two boxes should both have scrollbars on the bottom but the top one is in a fieldset so it won't control the overflow.</p>
  
  <p>How do I get the fieldset to only be as wide as it's parent?</p>
