title: Variable and jQuery selector
body: <p>I've been trying to figure this one out for about 2 days and cant understand why this isn't working. </p>
  
  <p>Say for example I declare a variable "ul" and want to say var + li display red.</p>
  
  <pre><code>$("document").ready(function () {
      var menu = $("ul");
      $(menu + " li").css("color", "red");
  });
  </code></pre>
  
  <p>All list items should now be red. What am I doing wrong? </p>
