CSS - percentage height
I can't get the middle div of 3 divs to fit 100% of available space.
<body>
<div id="container">
    <div id="header">
    </div>
    <div id="content">
    </div>
    <div id="footer">
    </div>
</div>
</body>
My CSS is:
html, body {
    margin: 0;
    padding: 0;
    border:1px;
    vertical-align:top;
    font-family:"Trebuchet MS", Arial, Helvetica, sans-serif;
    font-size:14px;
    color:#333;
    height: 100%;
}
#container {
    height: 100%;
    width: 100%;
}
#header {
    height: 100px;
    width: 100%;
    background: #069;
}
#content {
    height: 100%;
    width: 100%;
    background: #F60;
}
#footer {
    height: 75px;
    width: 100%;
    background: #060;
}
Center div is in effect being 100%, but its not fitting available space.
It is doing something like this: If the screen is 500px
30px
100% (500px)
30px
What I need is:
30px
100% (460px)
30px
Is this possible withouth using javascript?
Thanks a lot
EDIT:
Sorry I meant Height I have 3 elements, header, middle and footer. Header and footer have fixed height, but I want middle to fit all available space
Found another solution based on other stackoverflow question:
* { margin: 0; padding: 0 }
html, body {
    margin: 0;
    padding: 0;
    vertical-align:top;
    font-family:"Trebuchet MS", Arial, Helvetica, sans-serif;
    font-size:14px;
    color:#333;
    height: 100%;
    border: 0;
}
#header
{
    height: 100px;
    background:#C60;
}
#container
{
    min-height: 100%; 
    height: auto !important; /*Cause footer to stick to bottom in IE 6*/
    height: 100%; 
    margin: 0 auto -100px; /*Allow for footer height*/
    vertical-align:bottom;
    background:#096;
}
#footer
{
    height: 100px; /*Push must be same height as Footer */
    background:#C60;
}
HTML
