[RESOLVED] centering a div (not the text in it)

[Wiz Creations]

I'm not sure if I've done it before, but (if there is a way) what is the css to center a div tag. I can't remember how to do it.

This just made the text center:
#content {
text-align:center;
border:5px #000066 ridge;
background-color:#93DCFF;
padding:7px;
width:575px;
height:auto;
}
This code caused what is seen in the attached image (http://www.webdeveloper.com/forum/attachment.php?attachmentid=7151&stc=1):
<div id="content" align="center">
I don't want to use <center><div>...stuff...</div></center>

i got it by adding margin:0px auto; to both the body and #content items in the css.
