<p>
  With <a href="http://benalman.com/projects/jquery-misc-plugins/#loadadscript">jQuery loadAdScript</a> you can load third party ad network scripts that use <code>document.write</code> into specific containers. The only downside is that the ads will load serially.. but that's necessary to keep them from stepping on each others' toes. And the upside is that your site isn't completely borked!
</p>
<p>
  Requires the <a href="http://benalman.com/projects/jquery-message-queuing-plugin/">jQuery Message Queueing</a> plugin.
</p>

<h3>Sample ads</h3>

<p>
  In this example, the ads are hidden by default, and are only shown when their ad script has finished executing.
</p>

<div id="a" class="ad"></div>
<div id="b" class="ad"></div>
<div id="c" class="ad"></div>

<h3>The code</h3>

<div class="clear"></div>

<pre class="brush:js">
<?= htmlspecialchars( $shell['script'] ); ?>
</pre>

<?
$shell['html_body'] = ob_get_contents();
ob_end_clean();

// ========================================================================== //
// DRAW SHELL
// ========================================================================== //

draw_shell();
