HEAD Element: Document Meta-Information

Usage:                 <HEAD>...</HEAD>
Can Contain:       BASE, ISINDEX, LINK, META, SCRIPT, STYLE, TITLE
Can Be Inside:    HTML
Attributes:           HREF

HEAD contains general information about the document. This information is not displayed as part of the document text. The only mandatory HEAD element is TITLE; all others are optional. Since the HEAD is always much smaller than the body, this is faster than accessing an entire document, and can be extremely useful for quickly generating catalogs or indexes based on HEAD content.

Attributes
- HREF=??????

Example:

<HEAD>
<TITLE>HTML Summary</TITLE>
</HEAD>

HOME MAIN NEXT PREV

BASE Element: Base URL

Usage:                <BASE>
Can Contain:       empty
Can Be Inside:    HEAD
Attributes:           HREF, TARGET

BASE has a single mandatory attribute, HREF, which is assigned the base URL of the document.

Attributes
- HREF="base_url" Specifies the base URL of the document. The base URL is a URL indicating where a document was originally located. This is useful for documents moved away from their original URL--after moving the document, partial URLs that referenced neighboring documents are no longer valid. However, if the original URL address is specified in the BASE element, then relative URLs from this document are evaluated relative to this "base" URL and are correctly located from the original location.
- TARGET="target_window_name" (Netscape Frame)

Example:

ISINDEX Element: Searchable Document

Usage:                <ISINDEX>
Can Contain:       empty
Can Be Inside:    HEAD [BLOCKQUOTE, BODY, CENTER, DD, DIV, FORM, LI, TD, TH]
Attributes:           PROMPT, ACTION

ISINDEX informs the browser that the document can be examined using a keyword search, and that the browser should query the user for a search or query string. ISINDEX should be inside the HEAD only, not in the BODY.

Attributes
- PROMPT specifies the prompt that should be presented for this query.
- ACTION="url"

Examples:
- Example 1: ISINDEX element.
- Example 2: ISINDEX element with PROMPT ACTION.

TOP

Example 1: ISINDEX element.
File IsindexEx1.htm

<HTML>
<HEAD>
<TITLE>HTML ISINDEX Element Example 1</TITLE>
<ISINDEX>
</HEAD>
<BODY>
<H1>HTML ISINDEX Element Example 1</H1>
<P>Enter your search in the search field</P>
</BODY>
</HTML>

Example 1 Output: Click here to go to IsindexEx1.htm.

Example 2: ISINDEX element with PROMPT ACTION.
File IsindexEx2.htm

<HTML>
<HEAD>
<TITLE>HTML ISINDEX Element Example 2</TITLE>
<ISINDEX PROMPT="Enter your search in the search field" ACTION="IsindexEx2A.htm">
</HEAD>
<BODY>
<H1>HTML ISINDEX Element Example 2</H1>
<P>Enter your search in the search field</P>
</BODY>
</HTML>

Example 2 Output: Click here to go to IsindexEx2.htm.

LINK Element: Relationship to Other Documents

Usage:                <LINK>
Can Contain:       empty
Can Be Inside:    HEAD
Attributes:           HREF, ID, REL, REV, TITLE

LINK describes a relationship between a document and other documents or objects. For example, LINK can indicate a related index, a glossary, or perhaps different versions of the same document. Alternately, LINK can point to next or previous documents. This information could be used by a browser--for instance, to predict and preload documents it is likely to need, or to configure customized navigational buttons or menus. A document can have any number of LINK elements to represent these various relationships to other documents. The HREF attribute is mandatory, as is at least one of REL or REV.

Attributes are similar to the anchor (A) element, except ID.
- ID labels a LINK with an identifying label, which must be a name token. Using ID, LINK elements can themselves be referenced by a hypertext anchor, allowing for a level of indirection in link references.
- REL/REV see http://www.sg.com/papers/Relatioship.com

Example:

META Element: Document Meta-Information

Usage:                <META>
Can Contain:        empty
Can Be Inside:    HEAD
Attributes:           CONTENT, HTTP-EQUIV, NAME

META provides a place to put meta-information that is not defined by the other HEAD elements. This allows an author to more richly describe the document content for indexing and cataloging purposes. CONTENT attribute is mandatory and one of the NAME or HTTP-EQUIV attributes (but not both).

Attributes:
- NAME="name" Specifies the meta-information name (name token). The client program (browser) must understand what this name means. HTML does not currently define any values for NAME. META must content one of NAME or HTTP-EQUIV, but not both.
- HTTP-EQUIV="name" Specifies the meta-information equivalent to that communicated by the HTTP protocol within HTTP response header fields. META must content one of NAME or HTTP-EQUIV, but not both.
- CONTENT="string" (Mandatory) This assigns the content associated with the NAME or HTTP-EQUIV value of the META element.

Example:

The client or indexing program that is accessing the HEAD of this document must consequently understand the meanings behind the names.

HOME MAIN NEXT PREV

SCRIPT Element: Include a Program Script

Usage:                <SCRIPT>...</SCRIPT>
Can Contain:       script program code (characters)
Can Be Inside:    HEAD, BODY, any BODY element that allows content
Attributes:           LANGUAGE, SRC, TYPE

SCRIPT is used to include program scripts within an HTML document. The content of the element is treated as script program code, and is executed, if possible, by the browser. Browsers that do not understand SCRIPT elements or the language in which the script is written should ignore this element and its content.

Attributes:
- LANGUAGE="string" (optional) (Netscape Navigator and Internet Explorer only) Specifies the language of the script contained within the SCRIPT element. The only commonly supported values are LANGUAGE="JavaScript", for JavaScript and LANGUAGE="VBScript" for Visual Basic Script. Internet Explorer supports both languages. Netscape Navigator 3 supports only JavaScript.
- SRC="url" (optional) (Netscape Navigator only) Specifies the URL of a file that contains a script.
- TYPE="string" (Not yet supported) Gives the MIME type for the script referenced by the SRC attribute.

Example:

HOME MAIN NEXT PREV

STYLE Element: Stylesheet or Rendering Information

Usage:                <STYLE>...</STYLE>
Can Contain:       characters
Can Be Inside:    HEAD
Attributes:           none

STYLE contains stylesheet rendering instructions, to be applied to the document when displayed by the browser. STYLE allows rendering information to be placed within the document, and not as a second file referenced through a LINK element.

Attributes: none

Example:

<HEAD>
    <STYLE>
        BODY {
            background: url (wave.gif) black;
        }
        H1 {
            margin-top: 10px;
            color: #4P;
            text-align: left;
            font: 30px "Arial Alternative", gill, helvetica, snas-serif;
        }

...
</STYLE>
</HEAD>

HOME MAIN PREV

TITLE Element: Document Title

Usage:                <TITLE>...</TITLE>
Can Contain:       characters
Can Be Inside:    HEAD
Attributes:           none

TITLE contains the title of a document. Every document must have a TITLE, and can only have one.

Attributes: none

Example:

<HEAD>
<TITLE>HTML Summary</TITLE>
</HEAD>
