title: CSS selector for "foo that contains bar"?
body: <p>Is there a way to make a CSS Selector that matches the following?</p>
  
  <pre><code>All OBJECT elements
    which have a PARAM element inside of them
  </code></pre>
  
  <p>The selector</p>
  
  <pre><code>OBJECT PARAM
  </code></pre>
  
  <p>doesn't work, as it matches the PARAM, not the OBJECT.  I'd like to apply { display:none } to the objects; it's useless to apply that to the PARAMs.</p>
  
  <p>(I'm aware I could pull this off with jQuery - <code>$("object param").closest("object")</code> - and VanillaJS - <code>document.querySelector("object param").closest("object")</code> - but I'm trying to create CSS rules on a page.)</p>
