The Head Element
|
The HEAD element contains information about the current document,
such as its title, keywords that may be useful to search engines,
and other data that is not considered document content.
Elements within the HEAD are generally not displayed.

A typical HEAD might look like this:-
<HTML>
<HEAD> <TITLE>The WDVL: The Head Element</TITLE>
<META NAME = "Copyright"
CONTENT = "1997 CyberWeb SoftWare">
<META NAME = "Keywords"
CONTENT = "HEAD element, metadata,
title, meta tag, link tag, base tag"
<LINK rel = STYLESHEET
href = "http://Stars.com/WDVL.css"
Type = "text/css" >
</HEAD>
TITLE
defines the document title, and is always needed.
The title will not appear on the document as on printed documents.
It will usually appear in a window bar
identifying the contents of the window.
ISINDEX for simple keyword searches,
see PROMPT attribute.
Usually placed in the HEAD by the server or a server script/program
to indicate a simple search facility. Not usually placed in an HTML
file, but generated by program. It's a kind of degenerate form.
LINK
used to define relationships with other documents.
<LINK rev="RELATIONSHIP" rel="RELATIONSHIP" href="URL">
The rel attribute specifies the
relationship between the HTML file and the URL.
The rev attribute (for "reverse")
specifies the relationship between the URL and the HTML file.
META
used to supply meta info as name/value pairs.
Embeds document meta-information not defined by other HTML elements.
Could be very useful for automatic indexing.
BASE
defines base URL for resolving relative URLs.
A record of the original URL of the document: this allows you to
move the document to a new directory (or even a new site) and have
relative URLs access the appropriate place with respect to the
original URL.
STYLE
allows document-specific styles to be described.
The STYLE element provides a means for including rendering information
using a specified style notation. Information in the STYLE element
overrides client defaults and that of linked style sheets. It allows
authors to specify overrides, while for the most part using a generic
style sheet, and as such improves the effectiveness of caching schemes
for linked style sheets.
