WWW: What Is It? • The World Wide Web (WWW) is a breakthrough in new
technology designed to enable global, distributed information systems.
• From a user's perspective, the Web is a collection of documents, or pages, which contain text, images, and hypertext links to other pages.
• WWW merges the techniques of information retrieval and hypertext to create a powerful global information system. By simply pointing and clicking, the user has instant access to a mind-boggling collection of information, distributed across the globe.
• From an information providers point of view, the Web is an easy and efficient way of distributing any kind of information to a very large audience. Nobody is certain of how many users are on the Internet, but estimates start at 20 million.

Key Elements of Web• Hypertext: Non-linear links to anchors of the
same document, or to different documents on the same or different web site. – Using HTML (HyperText Markup Language) links and
anchors– Relying on URL (Uniform Resource Locators)
addressing scheme
• Multimedia: graphics, video, sound, etc. – Web browser can access networked hypermedia. – Hypermedia access of the web browser is facilitated
by helper applications, plug-ins, or document viewers.
• Network: Global reach and "Universal" access– Based on TCP/IP protocol.

Introduction to HTML• Most web pages on the World Wide Web are created in a
standard document format know as Hypertext Markup Language, or HTML.
• In practical terms, HTML is a collection of styles (indicated by markup tags) that define the various components of a World Wide Web document. HTML was invented by Tim Berners-Lee while at CERN.
• The "Hypertext" in HTML is the links that allow you to surf from one document to the next on the World Wide Web.
• All Web browsing tools like Microsoft Internet Explorer, and Netscape Navigator, read HTML documents and allow you to browse these documents by traversing these links.
• Not all browsing tools interpret or display HTML in the exact same way. This is why some pages look different in one browser than they do in another. It is important to keep this in mind when you are creating your web pages. Test your web pages on different browsers.

Physical and Logical Styles in HTML• If physical and logical styles produce the same result on the screen,
why are there both? It is because of the philosophy of SGML, which can be summed in a Zen-like mantra: "Trust your browser.''
• In the ideal HTML universe, content is divorced from presentation. Thus, HTML tags a level-one heading as a level-one heading, but does not specify that the level-one heading should be displayed.
• The advantage of this approach (it's similar in concept to style sheets in many word processors) is that if you decide to change level-one headings to be 20-point left-justified Helvetica, all you have to do is change the definition of the level-one heading in the presentation device (i.e., your World Wide Web browser) or cascading style sheet (CSS).
• The other advantage of logical tags is that they help enforce consistency in your documents. It's easier to tag something as <H1> than to remember that level-one headings are 24-point bold Times or whatever. The same is true for character styles. For example, consider the <STRONG> tag. Most browsers render it in bold text. However, it is possible that a reader would prefer that these sections be displayed in red instead. Logical styles offer this flexibility.
© Minder Chen, 1996-2002 HTML & Web Publishing - 29
Logical Styles• <DFN>: for a word being defined. Typically displayed in italics.
(NCSA Mosaic is a World Wide Web browser.)• <EM>: for emphasis. Typically displayed in italics. (Watch out for
pickpockets.)• <CITE>: for titles of books, films, etc. Typically displayed in italics.
(A Beginner's Guide to HTML)• <CODE>: for snippets of computer code. Displayed in a fixed-width
font. (The <stdio.h> header file)• <KBD>: for user keyboard entry. Should be displayed in a bold
fixed-width font, but many browsers render it in the plain fixed-width font. (Enter passwd to change your password.)
• <SAMP>: for computer status messages. Displayed in a fixed-width font. (Segmentation fault: Core dumped.)
• <STRONG>: for strong emphasis. Typically displayed in bold. (Important)
• <VAR>: for a "metasyntactic'' variable, where the user is to replace the variable with a specific instance. Typically displayed in italics. (rm filename deletes the file.)
© Minder Chen, 1996-2002 HTML & Web Publishing - 30
Physical Styles• <B>: bold text• <I>: italic text• <U>: Underline text (Don’t use it)• <TT>: typewriter text, e.g. fixed-width font• <PRE>: Use a non-proportional font to maintain the white spaces, tabs,
and carriage returns.
Examples: • <b>Boldface</b> • <PRE> This is a tabbed line </pre>• Correct: <b> <i> Boldface and italic </i> </b>
• Incorrect: <i> <b> Boldface and italic </i> </b>

Paragraph• The browser ignores any indentations or blank lines in
the source text. HTML relies almost entirely on the tags for formatting instructions, and without the <P> tags, the document becomes one large paragraph.
• <p>...</p> The closing tag </p> is optional • <p> Start a new paragraph• <p align=center> HTML 3.0 feature• <br> Force a line break • <!-- This is a comment line --> • <h1 align=center>...</h1> • <center>...</center> • <nobr> Do not wrap the enclosed text </nobr>• Force a space character

Paragraph: To Break or No To Break

Listing• HTML supplies five list elements. With the exception of
DL, list elements are composed of one or more LI (list item) elements. You can nest lists by inserting a UL, OL, etc., inside a list item (LI).
• Five list types: – OL: ordered list. Items in this list are numbered automatically by
the browser. The numbering will reflect nesting levels.– UL: unordered list. Items in this list start with a list mark such as a
bullet. Browsers will usually change the list mark in nested lists.– MENU: menu list. This is an unordered list. Each LI element in this
kind of list should be no longer than one line.– DIR: directory list. This is an unordered list. Each LI element in this
kind of list should be no longer than 24 characters.– DL: list of definitions. This is an unordered list. This kind of list is
different from the others. Each `item' in a DL consists of one or more terms (DT elements), followed by definitions (DD elements).

Special Characters• There are four characters that have special
meanings in HTML. When you want to use them, you need to have a special sequence pf characters (escape sequence) to represent them.
• These four characters are:< (the left angle bracket)
> (the right angle bracket)
& (ampersand)
" (quotation marks)
© Minder Chen, 1996-2002 HTML & Web Publishing - 41
Escape Sequences• HTML includes character combinations, called escape
sequences, to represent these characters in an HTML document, They are:
< (the escape sequence for <)> (the escape sequence for >)& (the escape sequence for &)" (the escape sequence for “)
(the escape sequence for space character)
• To display <HR> as it is in an HTML document, you should write it in the following two ways: – <HR>– <xmp><HR></xmp>
• Note: It is important to note that escape sequence are case-sensitive , unlike all other HTML tags.
© Minder Chen, 1996-2002 HTML & Web Publishing - 42
More Escape Sequences• There are many more escape sequences for non-ASCII
characters. Some of the more common ones are:
ö (the escape sequence for a lowercase o with an umlaut, ö)
&ntild; (the escape sequence for lowercase n with a title; ñ)
È (the escape sequence for an uppercase E with a grave accent; è)
© (Netscape extension for ©)
® (Netscape extension for ®)

Introduction to Hypertext• Definition of hypertext: "A combination of natural language text with the
computer's capacity for interactive branching, or dynamic display... of a nonlinear text." -- Ted Nelson
• The idea of hypertext system can be traced back to Vannevar Bush, President Roosevelt's Sciences Advisor, 1945 article "As We May Think" in which he described the idea of mechanize the scientific literature system.
• Now hypertext really means hypermedia that include not just text, but also audio, graphic, video, etc.
• Hypertext documents on WWW usually are stored in a special format called HTML, stands for HyperText Markup Language.
• A window will be used to view part of the hypertext document retrieved.
• On your Netscape Browser, the underlying HTML link to another Web document will be displayed at the message bar when you move mouse pointer over a link.

Hypertext Links• A hypertext link is a pointer pointing to another
document or another part of the current document. • These linked documents can be on the same WWW
server or on WWW servers distributed globally. • Hypertext links are represented as a purple color and
underlined texts, or as a graphic object (inline graphics). When you move the mouse cursor over a hypertext link, the mouse cursor will change from a pointer to a pointing hand.
• You may use Image Maps such that different parts of the graphic representing links to different documents.

Use a Relative URL• Examples:
– <a href="http://www.aitc.com/~mchen/fileX.htm"> Another file in the same directory</a>
– Can be written as <a href="fileX.htm">Another file in the same directory</a> – <a href="subdir/fileY.htm">Another file in the subdirectory under current
document's directory</a>
• Reasons to use relative URLs– Less typing is required to enter them.– If you move all the files to a different location but keep the same directory
structure you don't have to revise the URLs. – The same file referred to by a relative URL can be accessed by different
schemes (for example both 'http' and 'ftp').

• In Netscape: General Preferences|Helpers• Use the General Helpers preferences panel to create or
reconfigure how a file's format maps to a external helper application.
• Netscape has the built-in capability to interpret and display several formats, including the HTML format used by HTTP servers.
• Helper applications are used by Netscape to interpret files that it has retrieved but is unable to read.
• You can designate MIME file types (a method of differentiating file formats using a suffix appended to a file name), helper applications and their associated actions.
• When you display the Helpers general preferences panel, you see a scrolling text field that lists the file formats and helper applications available to Netscape.

<frameset> and </frameset>• This is the main container for a Frame. It has 2
attributes: ROWS and COLS. • A frame document has no <BODY> tag, and no
tags that would normally be placed in the BODY can appear before the FRAMESET tag, or the FRAMESET will be ignored.
• The FRAMESET tag has a matching end tag, and within the FRAMESET you can only have other nested FRAMESET tags, FRAME tags, or the NOFRAMES tag.
• FRAMESET attributes include:– ROWS="row_height_value_list" – COLS="column_width_list"
© Minder Chen, 1996-2002 HTML & Web Publishing - 121
<frame> </frame>• Load information independent of other frames• Can be given a target name• Can resize dynamically• This <frame> tag defines a single frame in a
frameset. • It has 6 possible attributes:
– SRC: The URL of the document to be displayed. – NAME: This is used to assign a name to a frame so that it can be
targeted by other links.– MARGINWIDTH: The left and right margin from the boundary of the
frame to the document and the value is in pixels.– MARGINHEIGHT: The upper and lower margins – SCROLLING: yes | no | auto– NORESIZE: Make the frame nonresizable. Frames are resizable by
default. – FRAMEBORDER: yes | no

<FRAMESET ROWS="value_list" COLS="value_list"></FRAMESET>
• A frame's window space can be divided into rows and columns.
• ROWS="value_list": This is a comma separated list of values. These values can be expressed in an absolute number of pixels, as a percentage (between 1 and 100) or as relative scaling values.
• Percentage: <FRAMESET ROWS="20%,60%,20%">• Pixels: <FRAMESET ROWS="100,500,100">; You'll almost certainly
want to use these values in combination with other percentage based or relative values.
• Relative scaling: <FRAMESET ROWS="50, 2*, *">; This is a mix of fixed and relative values. In this case the first ROW is 50 pixels wide. The other two rows are divide the remaining space. A single "*" means that the frame gets all of the remaining space. When more than one "*" appear, you can give them relative portions of the remaining space. In this case, the second row gets 2/3 of the
remaining space and the third row gets 1/3 of the remaining space.

Imagemap• ISMAP: The ISMAP (is map) attribute identifies an image as
an image map. Image maps are graphics in which certain regions are mapped to URLs. By clicking on different regions, different resources can be accessed from the same graphic. Example of use:
• <A HREF="book1.map"> <IMG SRC="sample.gif" ISMAP> </A>
• To be able to use image maps in HTML documents, the HTTP server which will be controlling document access must have the correct cgi-bin software installed to control image map behavior.
• Files needed: – "Map" image: sample.gif in the example.– Map file: e.g., book1.map in the example. Has two
formats: NCSA and CERN and you can use MapEdit or MAP This to create it.
– Imagemap CGI program on the web server

Limitations of Image Maps
• Image maps only work over the HTTP protocol.
• A server transaction is always required.
• The implementation of image maps is server-dependent.

URL and Security• URLs are standardized in RFC1738, and in their most
generic form, they are defined as
• <scheme>:<scheme-specific-part>
• The best-known scheme is the Common Internet (http for WWW), in which the <scheme> is the name of a protocol and the <scheme-specific-part> is defined as:
• //<user>:<password>@ <user>:<password>@ <host>:<port>/<url-path> in which only the host part is mandatory. – The ":" and "@" characters have a special meaning and thus the
server can parse the entire string.
– If a user and a password are provided, the host part only comes after the @ character.
