Help me plz!!What am I looking for? Looks the same in both to me.. IE 6.0.2800.1106 SP1, & Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.6) Gecko/20040206 Firefox/0.8Hmm then is something wrong with my IE. Border on the left side in IE is higer than in Mozilla.Putting IE in compliance mode by using up-to-date DTD will help minimize the differences in appearance.
