I am using the # in conjunction with other id classifications in the site and CSS, and the error is not reported. 11393 1 ot 2006-09-06 04:03:56 +0000 The problematic line, which is in your stylesheet (but you omitted when copying in your report) is: position-relative: top:0px; I don't think that's a correct construct in CSS. I suspect you want something like position: relative; top: 0px; Closing as "not a bug"
