I am using blogspot.com.  

I want to make my coding highlighting.  

So, I use google code prettify api.  

```
<link href='http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.css' rel='stylesheet' type='text/css'/> 

```

```
<pre class="prettyprint"> ... my coding place ... </pre>

```

Everything is fine but I would like to make Scrolling (like ., style="overflow-x: scroll")

Please let me know where should I modify to make scrolling of my code at blogspot.com
