How to resize content area with CSS dynamically and no javascript
I want is this:
- the blue area resizes with when the browser window resizes.
- The header is visible.
- the blue area starts where the header finishes (not behind the header or above).
- the blue area ends before the footer.
- between the blue area and the footer exist 5 yellow pixels.
Is this possible only with CSS and HTML ( without any javascript ) ?
<!doctype html>
<html lang="en-US">
<head>
<meta charset="utf-8"/>
<title>Test</title>
<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0;"/>

*{
margin:0px;
padding:0px;
}
header, nav, article, footer, address {
display: block;
}
header{
position:relative; height: 50px; background-color:#2b2b2b;
}
footer{
height: 50px;
width:100%;
bottom: 0px;
position: fixed;
background: red;
}
#explorer{
position:relative; bottom:55px;
}
#sections{
width: 100%; height: 100%; bottom: 55px; position:fixed; background: blue;
}
</style>
</head>
<body style="background-color:yellow">
<header >
<h1>Test</h1>
</header>
<div id="explorer" >
<div id="sections" >
</div>
</div>
<footer>
/* Footer Content */
</footer>
</body>
</html>
I think Kit's code needs just one adjustment & that is we have to remove the height:100% from the sections div & it will work just fine. Also while testing the following code, i noticed that if we reduce the height beyond a limit the footer actually comes above the header. Although, practically the height would never be so less, but still you might want to add z-index:5000 to header tag
Like this?
<html>
<head>
<meta charset="utf-8"/>
<title>Test</title>
<style type="text/css">
html, body, h1 {
margin:0px;
padding:0px;
}
header, nav, article, section, footer, address {
display: block;
}
header {
position:relative;
height: 50px;
width: 100%;
background-color:#2b2b2b;
}
footer{
height: 50px;
width:100%;
bottom: 0px;
position: fixed;
background: red;
border-top: 5px solid yellow;
}
#explorer{
position:relative; bottom:55px;
}
#sections{
width: 100%;
height: 100%;
bottom: 55px;
position:fixed;
top: 50px;
background: rgba(0,0,256,.5);
}
</style>
</head>
<body>
<header >
<h1>Test</h1>
</header>
<div id="explorer" >
<div id="sections" >
</div>
</div>
<footer>
/* Footer Content */
</footer>
</body>
