I've been working on a website for a friend using W3C strict html and css. I've noticed that despite specifying 0px margins to the <body> element in the style sheet, Opera 7 insists on placing a margin around the page. If I specify negative margins, I can get rid of it. IE, Firefox etc., do not exhibit this feature.
To Opera fans, is this a feature of Opera, or is there something I need to know about it?
