How do I force a DIV block to extend to the bottom of a page even if it has no content?
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:

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.
