Question

In the markup shown below, I'm trying to get the content div to stretch all the way to the bottom of the page but it's only stretching if there's content to display. The reason I want to do this is so the vertical border still appears down the page even if there isn't any content to display.

Here is my HTML:

<body>
    <form id="form1">
    <div id="header">
        <a title="Home" href="index.html" />
    </div>

    <div id="menuwrapper">
        <div id="menu">
        </div>
    </div>

    <div id="content">
    </div>

And my CSS:

body {
    font-family: Trebuchet MS, Verdana, MS Sans Serif;
    font-size:0.9em;
    margin:0;
    padding:0;
}
div#header {
    width: 100%;
    height: 100px;
}
#header a {
    background-position: 100px 30px;
    background: transparent url(site-style-images/sitelogo.jpg) no-repeat fixed 100px 30px;
    height: 80px;
    display: block;
}
#header, #menuwrapper {
    background-repeat: repeat;
    background-image: url(site-style-images/darkblue_background_color.jpg);
}
#menu #menuwrapper {
    height:25px;
}
div#menuwrapper {
    width:100%
}
#menu, #content {
    width:1024px;
    margin: 0 auto;
}
div#menu {
    height: 25px;
    background-color:#50657a;
}

Solution

Your problem is not that the div is not at 100% height, but that the container around it is not.This will help in the browser I suspect you are using:

html,body { height:100%; }

You may need to adjust padding and margins as well, but this will get you 90% of the way there.If you need to make it work with all browsers you will have to mess around with it a bit.

This site has some excellent examples:

OTHER TIPS

I'll try to answer the question directly in the title, rather than being hell-bent on sticking a footer to the bottom of the page.

Make div extend to the bottom of the page if there's not enough content to fill the available vertical browser viewport:

Demo at (drag the frame handle to see effect) : http://jsfiddle.net/NN7ky
(upside: clean, simple. downside: requires flexbox - http://caniuse.com/flexbox)

HTML:

<body>

  <div class=div1>
    div1<br>
    div1<br>
    div1<br>
  </div>

  <div class=div2>
    div2<br>
    div2<br>
    div2<br>
  </div>

</body>

CSS:

* { padding: 0; margin: 0; }

html, body {
  height: 100%;

  display: flex;
  flex-direction: column;
}

body > * {
  flex-shrink: 0;
}

.div1 { background-color: yellow; }

.div2 {
  background-color: orange;
  flex-grow: 1;
}

ta-da - or i'm just too sleepy

Try playing around with the following css rule:

#content {
    min-height: 600px;
    height: auto !important;
    height: 600px;
}

Change the height to suit your page. height is mentioned twice for cross browser compatibility.

you can kinda hack it with the min-height declaration

<div style="min-height: 100%">stuff</div>

Try Ryan Fait's "Sticky Footer" solution,

http://ryanfait.com/sticky-footer/
http://ryanfait.com/resources/footer-stick-to-bottom-of-page/

Works across IE, Firefox, Chrome, Safari and supposedly Opera too, but haven't tested that. It's a great solution. Very easy and reliable to implement.

The min-height property is not supported by all browsers. If you need your #content to extend it's height on longer pages the height property will cut it short.

It's a bit of a hack but you could add an empty div with a width of 1px and height of e.g. 1000px inside your #content div. That will force the content to be at least 1000px high and still allow longer content to extend the height when needed

While it isn't as elegant as pure CSS, a small bit of javascript can help accomplish this:

<html>
<head>
<style type='text/css'>
    div {
        border: 1px solid #000000;
    } 
</style>
<script type='text/javascript'>

    function expandToWindow(element) {
         var margin = 10; 

         if (element.style.height < window.innerHeight) { 
            element.style.height = window.innerHeight - (2 * margin) 
         }
    }


</script>
</head>
<body onload='expandToWindow(document.getElementById("content"));'>
<div id='content'>Hello World</div>
</body>
</html>

Try:

html, body {
    height: 102%;
}
.wrapper {
    position: relative;
    height: 100%;
    width: 100%;
}
.div {
    position: absolute;
    top: 0;
    bottom: 0;
    width: 1000px;
    min-height: 100%;
}

Haven't tested it yet...

Sticky footer with fixed height:

HTML scheme:

<body>
   <div id="wrap">
   </div>
   <div id="footer">
   </div>
</body>

CSS:

html, body {
    height: 100%;
}
#wrap {
    min-height: 100%;
    height: auto !important;
    height: 100%;
    margin: 0 auto -60px;
}
#footer {
    height: 60px;
}

I think the issue would be fixed just making the html fill 100% also, might be body fills the 100% of the html but html doesn't fill 100% of the screen.

Try with: 

html, body {
      height: 100%;
}

    </footer>
</body>

</html>

It isn't quite what you asked for, but it might also suit your needs.

I dont have the code, but I know I did this once using a combination of height:1000px and margin-bottom: -1000px; Try that.

Depending on how your layout works, you might get away with setting the background on the <html> element, which is always at least the height of the viewport.

It is not possible to accomplish this using only stylesheets (CSS). Some browsers will not accept

height: 100%;

as a higher value than the viewpoint of the browser window.

Javascript is the easiest cross browser solution, though as mentioned, not a clean or beautiful one.

You can use the "vh" length unit for the min-height property of the element itself and its parents. It's supported since IE9:

<body class="full-height">
    <form id="form1">
    <div id="header">
        <a title="Home" href="index.html" />
    </div>

    <div id="menuwrapper">
        <div id="menu">
        </div>
    </div>

    <div id="content" class="full-height">
    </div>
</body>

CSS:

.full-height {
    min-height: 100vh;
    box-sizing: border-box;
}

Not the very best nor the best implementation of the greatest standards, but you can change the DIV for a SPAN... It's a not so recommendable but fast fix =P =)

I know this is not the best method, but I couldnt figure it out without messing my header, menu, etc positions. So.... I used a table for those two colums. It was a QUICK fix. No JS needed ;)
