title: CSS: Hide an element when another element is hidden
body: <p>I have the following questions:</p>
  
  <p>I already have a code that hides <em>class element 1</em> when it has a specific value (which is not the same on all sites).</p>
  
  <p>Now I also want to hide <em>class element 2</em> ONLY IF <em>class element 1</em> is already hidden.</p>
  
  <p>Do you guys have any idea on how to do this?</p>
  
  <p>Thanks!</p>
