How to apply style to parent class, based on nested or deep child having some class?

How can I apply styles to tree Item or li, based on the child-class, using CSS or sass?

<li class="tree-item">
      <div class="k-mid">
          <div class="k`enter code here`-in">
          <span class="child-class">test`enter code here`</span>
        </div>
      </div>
    </li>
