JavaScript Conditional Comments for IE
<p>Here is the classic <strong>conditional comment</strong> to target Internet Explorer 9+ and all non-IE browsers:</p>

<pre><code>&lt;!--[if gt IE 8]&gt;&lt;!--&gt;
    IE 9+ and all non-IE browsers see this text.
&lt;!--&lt;![endif]--&gt;
</code></pre>

<p>What is the purpose of each of the 4 parts?</p>

<pre><code>&lt;!--[if gt IE 8]&gt;
&lt;!--&gt;
&lt;!--
&lt;![endif]--&gt;
</code></pre>
