  <p>I would like to the jQuery equivalent this CSS code:</p>
  
  <pre><code>p:before {
     content: 'Intro!';
  }
  </code></pre>
  
  <p>I've naively tried <code>$('p:before').css('content', 'Intro!');</code> but it doesn't work.</p>
  
  <p>How can I do pseudo-element CSS modifications using jQuery?</p>
