<script src="https://google-code-prettify.googlecode.com/svn/loader/run_prettify.js">

Marking code sections:

Now whenever you display code on your page, simply enclose it in <pre>…</pre>, <code>…</code> or <xmp>…</xmp> tags with a class of “prettyprint“. Here’s an example: 

<code class="prettyprint">
...YOUR_CODE_HERE...
</code>

If you don’t like the default skin, there are 4 other styles you can choose from (Available here):
