CSS Position / Height - 100% of Page vs. Screen - css

Question

So, I'm having an issue with CSS Positioning / Height
So, I'm trying to do a sliding navigation UI from the left side of the screen (like a lot of mobile apps). The main content slides over, displaying the navigation menu beneath.
I believe to do with positioning, I can't get height to work properly. I ultimately would like for 100% height to mean 100% of the entire page. Currently, only items that have more content will expand and the shorter ones stop at the screen edge (so they are 100% of screen vs. entire page).
Anyway here is my fiddle: http://jsfiddle.net/2vP67/6/
And here is the code within the post:
HTML
<div id='wrapper'>
<div id='navWide'> </div>
<div id='containerWide'> </div>
<div id='containerTall'>
<div id='container'>
<div id='nav'>
<div id='navNavigate'> Open Menu </div>
<div id='navNavigateHide'> Close Menu </div>
</div>
</div>
</div>
<div id='sideContainerTall'>
<div id='sideContainer'>
<div id='sideNav'>Side Navigation </div>
</div>
</div>
</div>
CSS

Javascript
$(document).ready(function() {
$('div#navNavigate').click(function() {
$('div#navNavigate').hide();
$('div#navNavigateHide').show();
$('div#sideContainer').show();
$('div#containerTall').animate({
'left': '+=264px'
});
});
$('div#navNavigateHide').click(function() {
$('div#navNavigate').show();
$('div#navNavigateHide').hide();
$('div#containerTall').animate({
'left': '-=264px'
}, function() {
$('div#sideContainer').hide();
});
});
});

Setting the height to 100% or any percent value relative to the browser window, for that matter, is illegal. This is because height cannot be set as a function of percent, because theoretically the browser window could go on forever with a scrollbar. Kind of a weird quirk. The only way you can achieve this is through javascript.
height = window.innerHeight;
getElementById('wrapper').style.height = height;
