title: Change CSS Property through JavaScript. (Uses ID's and Classes)
body: <p>I'm trying to resize a panel using JavaScript to fit a small image into a panel, and struggling badly.</p>
  
  <p>It's within the bold:</p>
  
  <pre><code>&lt;body id="visCinemaTransRefund"&gt;&lt;br&gt;
  &lt;div id="content"&gt;&lt;br&gt;
  &lt;ul class="PayPanel" id="paymentDetails"&gt;&lt;br&gt;
  </code></pre>
  
  <p>Here's the CSS that needs modifying:</p>
  
  <pre><code>visCinemaTransRefund .PayPanel { width: 435px; }
  </code></pre>
  
  <p>How would I be able to modify with width of this panel?</p>
  
  <p>I've also got a form I'm trying to resize within CSS:</p>
  
  <pre><code>visCinemaTransRefund FORM (width: 1005px;)
  </code></pre>
