I need a code where once you click on a link on the page it goes down to the middle or bottom of the page anyone know a code for this

For Instance if you go Here
and scroll down and click on payment info on the top nav it will take you to the middle of the page

<a href="#point-in-the-page-where-you-want-to-go">The link with pretty anchor text</a>

Where you want the user to go, put:

<a id="point-in-the-page-where-you-want-to-go"></a>

That's it.

thanks alot
