title: Dropdown menu for mobile devices
body: <p>I'm looking for a way to do it, or a simple "You have to use JavaScript."</p>
  
  <p>Is it possible to make a pure CSS dropdown menu for mobile devices, or do I have to use JavaScript?</p>
  
  <p>I tried using the :focus pseudo, but I can't click the links, even though the menu opens (It closes before the link in clicked).
  The :active pseudo doesn't even work half way.</p>
  
  <p>So is there some trick to doing this, or do I need to use JavaScript?</p>
