100% height not working great

I am using dreamweaver to help me write my CSS code, and I am making a div layout. Now I feel comfortable using divs, but something has prevented me from working.

I have a 100% height issue. My code goes as this...

Code: Select all

#main
{
height:100%;
width:600px;
}

Basically dreamweaver and IE are responding to this 100% deal as acutally 5pixles, because thats as tall as it wants to go. It looks like it works perfectly for most people, except for me. Can anyone help me?

(I dont have this code uploaded online. I dont think I really need to in this situation...)

What are you trying to do? Try adding this to your CSS:

Code: Select all

html, body {
    margin: 0;
    padding: 0;
    height: 100%;
}

There are several solutions, but it all lies on what you're trying to do.
