title: How can I exclude last two child elements with CSS selector?
body: <p>I want to draw <code>bottom-border</code> under some div elements inside their parent but except the last two, knowing that number of child element is changeable:</p>
  
  <pre><code>&lt;div id="parent"&gt;
     &lt;div&gt;
  One
     &lt;/div&gt;
     &lt;div&gt;
  Two
     &lt;/div&gt;
     &lt;div&gt;
  Three
     &lt;/div&gt;
     &lt;div&gt;
  Four
     &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Is it possible to select all child elements except the last two?</p>
