Build site with content sliding in, static header etc

SPA ( single page application ) is what you are looking for. But if you are asking questions about it on an Apple forum it may be a little beyond your current programming capabilities.

You could do exactly what you are looking to do with just a little javascript as well, but it will not be an optimized solution without using some AJAX ( hence the SPA recommendation ).

Build your site with a div for each content:

Code:

<div id='nav-item-1'>Page Stuff goes here</div>
<div id='nav-item-2'>More page stuff</div>

Hide every div using CSS ( display: none; ) except for the 'Home' page.

Then as users click nav items, capture the click using javascript and 'slide' the div in from the left or right.

Good luck and post us a link in JSFiddle when you have trouble or have solved it!
