Moving the page
<p>I need to move the page from top to bottom, just like it happens in the best site of the world( <a href="http://stackoverflow.com/">stackoverflow</a>), when we change the type of sorting of our questions, it moves the page.</p>

<p>How can I get such an effect?
I even don't know how to search for information about it, because don't know the <em>keywords</em>, so I decided to ask here :/</p>

<p>Thanks</p>
