title: CSS: set style only for li that have inside an ul
body: <p>I have an unordered list (ul) with some list items (li). One of this have another unordered list inside (ul). Now, I want to se to all these li the same stylesheet, except for the li that have another unordered list inside.</p>
  
  <pre><code>&lt;ul&gt;
      &lt;li&gt;Element&lt;/li&gt;
      &lt;li&gt;Another Element&lt;/li&gt;
      &lt;li&gt;Special Element
          &lt;ul&gt;
              &lt;li&gt;Child&lt;/li&gt;
              &lt;li&gt;Child&lt;/li&gt;
          &lt;/ul&gt;
      &lt;/li&gt;
  &lt;/ul&gt;
  </code></pre>
  
  <p>How can I set CSS without set a specific class for the special li?</p>
