Simple 100% CSS Height example not working, can someone help please - html

Question

I have a very simple CSS 100% example, that logically as I understand it, should work, but doesn't. Can someone please explain why?
HTML:
<div id="header">header</div>
<div id="nav">Nav</div>
<div id="title">title</div>
<div id="content">
Content
</div>
CSS:
html {
height:100%;
padding: 0;
margin: 0;
}
body {
height: 100%;
padding: 0;
margin: 0;
}
#header {
background-color:red;
padding: 0;
margin: 0;
}
#nav {
background-color:gray;
padding: 0;
margin: 0;
}
#title {
background-color:azure;
padding: 0;
margin: 0;
}
#content {
background-color:antiquewhite;
height:100%;
padding: 0;
margin: 0;
}
To my understanding, there should be no vertical scroll bar. Yet one appears.
Here is a fiddle to demonstrate: http://jsfiddle.net/codeowl/9wABW/
Thank you for your time,

UPDATE:
Here is what I ended up doing:
I developed a stack and fill approach as follows. Unfortunately fiddle has an issue with me trying to access the window in java script, so I can only paste the code:
CSS:
#header {
background-color:red;
}
#nav {
background-color:gray;
}
#title {
background-color:azure;
}
#content {
background:green;
}
HTML:
<div id="header" class="stack-y">header</div>
<div id="nav" class="stack-y">Nav</div>
<div id="title" class="stack-y">title</div>
<div id="content" class="fill-y">
<div data-role="splitter"
data-panes="[
{ scrollable: false, collapsible: true, size: '300px' },
{ scrollable: false, collapsible: true }
]"
class="fill-y">
<div>
Left Pane
</div>
<div>
Right Pane
</div>
</div>
<div class="stack-y">Test Content</div>
</div>
Java Script:
$(document).ready(function () {
var fResizeLayout = null;
fResizeLayout = function() {
var aFillElements = $('.fill-y');
$.each(aFillElements, function (i, e) {
var p = null,
iPY = 0,
iY = 0,
iH = 0;
e = $(e);
p = e.parent();
if (p.prop('tagName') === 'body') { iPY = $(window).height(); }
else { iPY = p.innerHeight(); }
e.siblings('.stack-y').each(function () {
iY += $(this).outerHeight(true);
});
iH = (iPY - iY - parseInt(e.css('border-top-width'), 10) - parseInt(e.css('border-bottom-width'), 10));
e.height(iH);
});
kendo.resize($('#content'));
};
kendo.init($('#content'));
fResizeLayout();
$(window).on('resize', function () {
if (this.resizeTO) clearTimeout(this.resizeTO);
this.resizeTO = setTimeout(function () {
$(this).trigger('resizeEnd');
}, 200);
});
$(window).on('resizeEnd', function () {
fResizeLayout();
});
});
Of course you will need to include the kendo libraries for the kendo part to work.
<link href="http://cdn.kendostatic.com/2013.3.1119/styles/kendo.common.min.css" rel="stylesheet" type="text/css" />
<link href="http://cdn.kendostatic.com/2013.3.1119/styles/kendo.default.min.css" rel="stylesheet" type="text/css" />
<script src="http://code.jquery.com/jquery-1.9.1.min.js"></script>
<script src="http://cdn.kendostatic.com/2013.3.1119/js/kendo.all.min.js"></script>
Without the keno libraries:
HTML:
<div id="header" class="stack-y">header</div>
<div id="nav" class="stack-y">Nav</div>
<div id="title" class="stack-y">title</div>
<div id="content" class="fill-y">
Test Fill Content
</div>
<div class="stack-y">Test Stacked Content</div>
Java Script:
$(document).ready(function () {
var fResizeLayout = null;
fResizeLayout = function() {
var aFillElements = $('.fill-y');
$.each(aFillElements, function (i, e) {
var p = null,
iPY = 0,
iY = 0,
iH = 0;
e = $(e);
p = e.parent();
if (p.prop('tagName') === 'body') { iPY = $(window).height(); }
else { iPY = p.innerHeight(); }
e.siblings('.stack-y').each(function () {
iY += $(this).outerHeight(true);
});
iH = (iPY - iY - parseInt(e.css('border-top-width'), 10) - parseInt(e.css('border-bottom-width'), 10));
e.height(iH);
});
};
fResizeLayout();
$(window).on('resize', function () {
if (this.resizeTO) clearTimeout(this.resizeTO);
this.resizeTO = setTimeout(function () {
$(this).trigger('resizeEnd');
}, 200);
});
$(window).on('resizeEnd', function () {
fResizeLayout();
});
});

Thanks to all those that contributed.
Hopefully this can help someone else.

Answer 1

Edit
This will give exactly the layout you are looking for, using display:table-row in the wrapped content.
html {
height:100%;
padding: 0;
margin: 0;
}
body {
height: 100%;
padding: 0;
margin: 0;
}
#header {
background-color:red;
padding: 0;
margin: 0;
display: table-row;
height:1px;
}
#nav {
background-color:gray;
padding: 0;
margin: 0;
display:table-row;
height:1px;
}
#title {
background-color:azure;
padding: 0;
margin: 0;
display:table-row;
height:1px;
}
#content {
background:green;
padding: 0;
margin: 0;
display:table-row;
}
#wrapper {height:100%;width:100%;margin:0;padding:0;display:table}
<div id="wrapper">
<div id="header">header</div>
<div id="nav">Nav</div>
<div id="title">title</div>
<div id="content">
Content
</div>
</div>
Check your updated fiddle
You need a wrapper for the elements, depending on your specific layout you might want to play with table css attributes (display: table-row etc).
<div id="wrapper">
<div id="header">header</div>
<div id="nav">Nav</div>
<div id="title">title</div>
<div id="content">
Content
</div>
</div>
html {
height:100%;
padding: 0;
margin: 0;
}
body {
height: 100%;
padding: 0;
margin: 0;
}
#header {
background-color:red;
padding: 0;
margin: 0;
}
#nav {
background-color:gray;
padding: 0;
margin: 0;
}
#title {
background-color:azure;
padding: 0;
margin: 0;
}
#content {
padding: 0;
margin: 0;
}
#wrapper {height:100%;margin:0;padding:0;background-color:antiquewhite;}

Answer 2

instead of using height:100% use height:auto..and it will work..:)

Answer 3

Think about what you are doing. you are telling content to be 100% of it's containing element. This would be body.
Thus, content will take up the size of the window, but you still have three other divs with height, thus total content size will = 100% (body size) + header + nav + title
If you want to fix this, you could simply make the inner contents add up to 100% and adjust the percentages to what you need. Take a look:
