Hi.

I’m sure someone has asked this question, but I couldn’t find it anywhere.  
I’m trying to postion my container div in the center of the page, with NO margin at the top or bottom, and a height of 100%.

body  
{  
margin:0;  
padding: 0;  
}  
#container  
{  
margin: 0px auto;  
padding: 0;  
width: 1000px;  
height: 100%;  
}

I can’t figure out when height:100% works or not (it’s not working here) and even if I define a height in pixels, the container won’t start at the top of the page (IE6, Mozilla). Isn’t there a way to get this effect without giving the div a negative margin?

Thanks for your help.
