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

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.

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;}
