Yeah, sorry for the mistake. Yes, you are right in this case bad code would look like :

    <ul class='collection'>
        <li>
          Is red
          <ul class='collection'>
            <li class='collection-special'>Should be blue</li>
          </ul>
        </li>
    </ul>

    
    .collection > li { color: red; }
    .collection-special { color: blue; }
