No matter what method you would use to control the page margins, you would
have to touch each page. There is no way to do it 'globally' although you
could certainly do a global search and replace to find -
</head>
and replace it with -
<style type="text/css">
<!--
body { margin:10px; }
-->
</style>
</head>
(this would give you a 10px margin top, right, bottom and left)
www.jimcoaddins.com - there's a plugin that allows you to set the <body
leftmargin, top margin, marginwidth, marginheight> attributes.
Else you can do it through Styles, add the margin attributes to your CSS and
then apply the style to all pages (this can also be done in one hit through
Frontpage.
