<p>Some source code on this blog can be downloaded.
Most of time, the code is larger than the <code>div</code> bloc.
This is why I use a method to show this code in a large jQuery popup. </p>
<p>You can try clicking the following code&nbsp;; remark that the content is cutted a bit after <code>z-index</code>:</p>

<p>This code is the one I use to obtain this result.</p>
<p>What does it do?</p>
<p>At the loading of the page, I create a <code>div</code> as wide as the window.
This <code>div</code> is a bit transparent. Then I hide it. I also take care to its <code>z-index</code> value to be sure it is behind all elements.</p>
<p>Then when we click on a <code>div</code> of class <code>code</code>, I copy the content into this new wide <code>div</code>, and I show it.
Really simple but really efficient.
No need to use a <code>jQuery</code> plugin.</p>
