<p>What does this code 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>
