Top and bottom margin for container/wrapper divs

[jimz]

If you use auto for the left and right it will center the div horizontally, I tried using the following code to center the div vertically but it dosen't work.

Is there a way to center the div vertically?

#container{ margin-top: auto;
margin-bottom: auto;
margin-left: auto;
margin-right: auto;
width:700px;
height:510px;
}


Thanks!
Jim.

position: relative; (if not, try absolute)
top: 50%;
height: 400px; (must declare a height)
margin-top: -200px; (must be half the above height)
