css hide div if div has no child with class

Is it possible to hide a div with css if the div has no child div's with a specific class name?

<div class="parent">
 This div must be hidden
</div>

<div class="parent">
 This div must be visible
 <div class="child">
 child div
 </div>
</div>

If it's not possible with CSS, maybe with javascript or jQuery?
