Code:
body {
 font-family: Helvetica, Verdana, Arial, sans-serif;
 font-size: 12px;
 color: black;
 margin-top: 0px;
 margin-left: 0px;
}
Opera ignores the margin-top and margin-left! It also ignores margin: 0px; when I use it. Is this a known problem? Are there any workarounds that are still CSS-valid and XHTML 1.0 Strict?
