title: Change css of multiple elements
body: <p>I just want to know if instead of </p>
  
  <pre><code>$(".element1").css('background','#000');
  $(".element2").css('background','#000');
  </code></pre>
  
  <p>It is possible to concatinate multiple elements to have them affected by one command or if there is a more efficient way like so:</p>
  
  <pre><code>$(".element1",".element2").css('background','#000');
  </code></pre>
