CSS - Centering a page - then making the page 100% height

Question

I\'m trying to center a page and then make it 100% in height. I have a div called \"content\" as the parent element of all elements in the HTML page. What do I need

Answer 1

This works for me in Firefox 3 & Safari 3. Don't have access to IE.

html{
  position:absolute;
  top:0;
  bottom:-1px;
  left:0;
  right:0;
  height:100%;
  text-align:center;
}
body{
  text-align:left;
  margin-left:auto;
  margin-right:auto;
  margin-top:0;
  min-height:100%;
  min-width:30em;
  max-width:50em;
  width:expression("40em");/*IE doesn't support max/min width*/
  padding:0 1em 0 1em;
}
