Something like this

<html>
<body style="height:100%; width:100%">
<div id="header" style="position:absolute; top:0px; left:0px; height:200px; right:0px;overflow:hidden;">
</div>
<div id="content" style="position:absolute; top:200px; bottom:200px; left:0px; right:0px; overflow:auto;">
</div>
<div id="footer" style="position:absolute; bottom:0px; height:200px; left:0px; right:0px; overflow:hidden;">
</div>
</body>
</html>

As of 2013: This would be my approach. jsFiddle:


HTML

<header class="container global-header">
<h1>Header (fixed)</h1>
</header>


<div class="container main-content">
<div class="inner-w">
<h1>Main Content</h1>
</div><!-- .inner-w -->
</div> <!-- .main-content -->


<footer class="container global-footer">
<h3>Footer (fixed)</h3>
</footer>


SCSS

// User reset


* { // creates a natural box model layout
-moz-box-sizing: border-box;
-webkit-box-sizing: border-box;
box-sizing: border-box;
} // asume normalize.css




// structure


.container {
position: relative;
width: 100%;
float: left;
padding: 1em;
}




// type


body {
font-family: arial;
}


.main-content {
h1 {
font-size: 2em;
font-weight: bold;
margin-bottom: .2em;
}
} // .main-content




// style


// variables
$global-header-height: 8em;
$global-footer-height: 6em;


.global-header {
position: fixed;
top: 0; left: 0;
background-color: gray;
height: $global-header-height;
}


.main-content {
background-color: orange;
margin-top: $global-header-height;
margin-bottom: $global-footer-height;
z-index: -1; // so header will be on top
min-height: 50em; // to make it long so you can see the scrolling
}


.global-footer {
position: fixed;
bottom: 0;
left: 0;
height: $global-footer-height;
background-color: gray;
}

If you're targeting browsers supporting flexible boxes you could do the following.. http://jsfiddle.net/meyertee/AH3pE/

HTML

<div class="container">
<header><h1>Header</h1></header>
<div class="body">Body</div>
<footer><h3>Footer</h3></footer>
</div>

CSS

.container {
width: 100%;
height: 100%;
display: flex;
flex-direction: column;
flex-wrap: nowrap;
}


header {
flex-shrink: 0;
}
.body{
flex-grow: 1;
overflow: auto;
min-height: 2em;
}
footer{
flex-shrink: 0;
}

Update:
See "Can I use" for browser support of flexible boxes.

Here's what worked for me. I had to add a margin-bottom so the footer wouldn't eat up my content:

header {
height: 20px;
background-color: #1d0d0a;
position: fixed;
top: 0;
width: 100%;
overflow: hide;
}


content {
margin-left: auto;
margin-right: auto;
margin-bottom: 100px;
margin-top: 20px;
overflow: auto;
width: 80%;
}


footer {
position: fixed;
bottom: 0px;
overflow: hide;
width: 100%;
}

Approach 1 - flexbox

It works great for both known and unknown height elements. Make sure to set the outer div to height: 100%; and reset the default margin on body. See the browser support tables.

jsFiddle

html, body {
height: 100%;
margin: 0;
}
.wrapper {
height: 100%;
display: flex;
flex-direction: column;
}
.header, .footer {
background: silver;
}
.content {
flex: 1;
overflow: auto;
background: pink;
}
<div class="wrapper">
<div class="header">Header</div>
<div class="content">
<div style="height:1000px;">Content</div>
</div>
<div class="footer">Footer</div>
</div>

Approach 2 - CSS table

For both known and unknown height elements. It also works in legacy browsers including IE8.

jsFiddle

html, body {
height: 100%;
margin: 0;
}
.wrapper {
height: 100%;
width: 100%;
display: table;
}
.header, .content, .footer {
display: table-row;
}
.header, .footer {
background: silver;
}
.inner {
display: table-cell;
}
.content .inner {
height: 100%;
position: relative;
background: pink;
}
.scrollable {
position: absolute;
left: 0; right: 0;
top: 0; bottom: 0;
overflow: auto;
}
<div class="wrapper">
<div class="header">
<div class="inner">Header</div>
</div>
<div class="content">
<div class="inner">
<div class="scrollable">
<div style="height:1000px;">Content</div>
</div>
</div>
</div>
<div class="footer">
<div class="inner">Footer</div>
</div>
</div>

Approach 3 - calc()

If header and footer are fixed height, you can use CSS calc().

jsFiddle

html, body {
height: 100%;
margin: 0;
}
.wrapper {
height: 100%;
}
.header, .footer {
height: 50px;
background: silver;
}
.content {
height: calc(100% - 100px);
overflow: auto;
background: pink;
}
<div class="wrapper">
<div class="header">Header</div>
<div class="content">
<div style="height:1000px;">Content</div>
</div>
<div class="footer">Footer</div>
</div>

Approach 4 - % for all

If the header and footer are known height, and they are also percentage you can just do the simple math making them together of 100% height.

html, body {
height: 100%;
margin: 0;
}
.wrapper {
height: 100%;
}
.header, .footer {
height: 10%;
background: silver;
}
.content {
height: 80%;
overflow: auto;
background: pink;
}
<div class="wrapper">
<div class="header">Header</div>
<div class="content">
<div style="height:1000px;">Content</div>
</div>
<div class="footer">Footer</div>
</div>

jsFiddle

Now we've got CSS grid. Welcome to 2019.

/* Required */
body {
margin: 0;
height: 100%;
}


#wrapper {
height: 100vh;
display: grid;
grid-template-rows: 30px 1fr 30px;
}


#content {
overflow-y: scroll;
}


/* Optional */
#wrapper > * {
padding: 5px;
}


#header {
background-color: #ff0000ff;
}


#content {
background-color: #00ff00ff;
}


#footer {
background-color: #0000ffff;
}
<body>
<div id="wrapper">
<div id="header">Header Content</div>
<div id="content">

</div>
<div id="footer">Footer Content</div>
</div>
</body>

It works fine for me using a CSS grid. Initially fix the container and then give overflow-y: auto; for the centre content which has to get scrolled i.e other than header and footer.

.container{
height: 100%;
left: 0;
position: fixed;
top: 0;
width: 100%;
display: grid;
grid-template-rows: 5em auto 3em;
}


header{
grid-row: 1;
background-color: rgb(148, 142, 142);
justify-self: center;
align-self: center;
width: 100%;
}


.body{
grid-row: 2;
overflow-y: auto;
}


footer{
grid-row: 3;
   

background: rgb(110, 112, 112);
}
<div class="container">
<header><h1>Header</h1></header>
<div class="body">
