HTML and CSS Reference
In-Depth Information
The structure of an XHTML document is pretty much the same with the exception of a
different
<!DOCTYPE>
indicator and an
xmlns
(XML name space) attribute added to the

</body>
</html>
Filename: template.html

<body>
tag with a
<frameset>
tag, which encloses potentially numerous
<frame>
tags

frames
. Each frame in
turn would reference another HTML/XHTML document containing either a standard
document, complete with
<html>
,
<head>
, and
<body>
tags, or perhaps yet another
framed document. The
<frameset>
tag also should include a
noframes
element that
provides a version of the page for browsers that do not support frames. Within this element,
