I was using
Code:
<body style="width:400px;">
and it properly restricted the text to 400 pixels wide. but the browser still does the scroll bar across the bottom of the screen and lets you slide the text off the screen.
The browser seems to allow wide screens. It seems reasonable for viewing web pages. But it allows an XHTML document to scroll text off the screen.
I was watching the scroll bar as I zoomed in and out. It works really well. It just isn't doing what I want.
