The HyperText Markup Language (HTML) is composed of a set of elements that define a document and guide its display. This document presents a concise reference guide to HTML, listing almost all of the elements, and giving a brief description of those elements.

Users should be aware that HTML is an evolving language, and different World-Wide- Web browsers may recognize slightly different sets of HTML elements.

An HTML element may include a name, some attributes and some text or hypertext, and will appear in an HTML document as

For example:

<title> My Useful Document </title>

and

<a href="http://cctr.umkc.edu"> text </a>

An HTML document is composed of a single element:

<html> . . . </html>

that is, in turn, composed of head and body elements:

<head> . . . </head>

and

<body> . . . </body>

To allow older HTML documents to remain readable, <html>, <head>, and <body> are actually optional within HTML documents.

Elements usually placed in the head element

<title> . . . </title>

Specify a document title. Note that the title will not appear on the document as is customary on printed documents. It will usually appear in a window bar identifying the contents of the window. HTML header tags perform the functions usually reserved for titles.

Link

The link tag allows you to define relationships between thedocument containing the link tag and the document specified in the "URL".

<A href="http://cctr.umkc.edu">

Elements usually placed in the body element

The following sections describe elements that can be used in the body of the document.

Text Elements

<p> - The end of a paragraph that will be formatted before it is displayed on the screen.
<pre> . . . </pre> - Identifies text that has already been formatted (preformatted) by some other system and must be displayed as is.

The structure of a Uniform Resource Locator (URL) may be expressed as:

resource_type://host.domain/pathname

where the possible resource types include: file, http, news, gopher, telnet, ftp, and wais, among others, and each resource type interprets the pathname in its own way. Note that each resource type relates to a specific server type.
