Basically, page jumps are just link, but links that point a certain part of document.

 This is done by assigning names to parts of your page and then making the link by referring to that section.

 Syntax

 <a name="top">....</a>
<a href="#top"> Go top </a>

 Note that the hash mark (#). That tells the browser that it's a section of a page it's looking for, and not a separate page or folder.
