Webmaster Forum / HTML, CSS, Scripts / CSS / January 2005Body width/height 100%
How do you give a <body> a 10px margin on every side, then a border? That is, an inset border. In the example below, the browsers I've tried interpret "width:100%" as 100% of the width including margins (the same width the height). As the actual display area for the body contents is the window display area minus the CSS margin, scroll bars show up. I don't want hard-coded dimensions, the body should resize and reflow (and, when needed, scroll bars show up) as the window is resized. -- Joakim Braun <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> <html> <head> <title>demo</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> <style type="text/css"> body{margin:10px;border:1px solid black;width:100%;height:100%;} </style> </head> <body> </body> </html> > How do you give a <body> a 10px margin on every side, then a border?

What do you want to happen to the border when (a) the content of the body doesn't fill the viewport (b) it's larger, so it needs to scroll? > In the example below, the browsers I've tried interpret > "width:100%" as 100% of the width including margins (the > same width the height). As it's supposed to (whether or not one thinks that is a sensible model). If you set width: auto you get something more agreeable. For height, it's not clear where you want the bottom border to appear. If you set height: auto, you'll get something which, when the content is large enough, will leave a 10px margin at the bottom when scrolled to the bottom, but a much bigger one if the content isn't big enough.

I'm not sure whether this is behaviour one can rely upon, though. SignatureJón Fairbairn Jon.Fairbairn@cl.cam.ac.uk > How do you give a <body> a 10px margin on every side, then a border?

Forget the 10px and go with a small percentage, say 2 or 3? Then subtract your percentage for margins from the width you want. Height is another story. Body height is based upon content rather than browser window size. It's better to leave it alone although you can go through some contortions to set it. Do some studying at: http://www.w3.org/TR/REC-CSS2/ about absolute positioning and possibly margins if you REALLY want to still set the height. I can't tell you right off as this is something I don't even try to do.

What I'm trying to do is have an inset frame around the whole page, with the contents being a header at the top stretching over 100% of the body width minus margins, and below that an iframe filling the rest of the available body area (and having scroll bars when needed). So the inset frame would remain at most window sizes. -- Joakim Braun > What I'm trying to do is have an inset frame around the whole page, with the > contents being a header at the top stretching over 100% of the body width > minus margins, and below that an iframe filling the rest of the available > body area (and having scroll bars when needed).
