How can I stretch a div to 100% page height?

Answer 1

html {
    height: 100%;
}

This will not work if you have a DOCTYPE. I'm looking for an answer too, but I have a DOCTYPE. However, there is a way to do it with a DOCTYPE, but it doesn't work with two divs floating left and right next to eachother, try:

(div-name) {
    position: absolute;
}

Be aware that this doesn't look good at all when using two divs floating next to eachother. But, it works fine for any other type.
