title: Change bg color when radio btn is selected
body: <p>I need to change the bg color of a div containing a radio button when the user slects the button. I am using jquery - so its seems like there should be some simple way to accomplish this. I have my html setup something like this: </p>
  
  <pre><code>&lt;div class="sales_box"&gt;
  &lt;table&gt;
  &lt;tr&gt;
  &lt;td class="radio_cell"&gt;&lt;input type="radio"&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;/table&gt;
  &lt;/div&gt;
  
  &lt;div class="sales_box"&gt;
  &lt;table&gt;
  &lt;tr&gt;
  &lt;td class="radio_cell"&gt;&lt;input type="radio"&gt;&lt;/td&gt;
  &lt;/tr&gt;
  &lt;/table&gt;
  &lt;/div&gt;
  </code></pre>
