HTML and CSS Reference
the <body> and </body> tags in your HTML documents, too, to make them
more easily readable and maintainable.
The various attributes for the <body> tag can be loosely grouped into
three sets: those that give you some control over the document's ap-
pearance, those that associate programmable functions with the docu-
ment itself, and those that label and identify the body for later refer-
ence. We address the appearance attributes ( alink , background , bgcolor ,
bgproperties , leftmargin , link , text , topmargin , and vlink ) in Chapter
stylesheets and the programmatic attributes (the "on-event" ones) in
Chapter 12 ; the language attributes ( dir and lang ) earlier in this
chapter; and the identification attributes ( id and title ) in Chapter 4 .
The HTML and XHTML standards define a special type of document in
which you replace the <body> tag with one or more <frameset> tags. This
so-called frame document divides the display window into one or more
independent windows, each displaying a different document. We thor-
oughly describe this innovation in Chapter 11 .
