<b>
<blockquote cite="">
<code>
<em>
<i>
<p>
<pre class="html|css|javascript|html-multi">
<del>
<strong>

Posting Sample Code

If you are posting sample JavaScript, or HTML then you might want to take advantage of the automatic syntax-highlighting available on this site. To do this, enclose your code in <pre> tags and assign the appropriate class (shown above).
