6 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.

7 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.

9 HTTP HTTP: HyperText Transfer Protocol Characteristics:
Runs on top of TCP/IP Has a comprehensive addressing scheme, i.e. URL An extensible and open representation for data type, using MIME header Has a stateless protocol. There is no memory between client connections. Is efficient Is portable Possible extensions, Secure HTTP (SHPPT), SSL, HTTP-Next Generation

22 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.

25 Basic Elements of HTML Coding
Basic Markup Tags Titles Headings Paragraphs Lists Unnumbered Lists Numbered Lists Definition Lists Nested Lists Preformatted Text: <pre> Extended Quotes Addresses Line Breaks Horizontal Rules <hr> <br> and <nobr> Character Formatting Physical Versus Logical: Use Logical Tags When Possible Using Character Tags: <b> <i> Special Characters Escape Sequences

26 HTML Tags: Document Structure
<HTML></HTML>: start and end of HTML document <HEAD></HEAD>: document meta-information start and end <BODY></BODY>: content of document displayed by the browser

27 Headings: Level 1 to 6 Xxxxx dsfdsfdsf sadsdsad 2.1 sadsad 2.2 ddddd
<html> <head> <title>Headings </title> </head> <body> <h1>Heading 1 (Top Level)</h1> <h2>Heading 2</h2> <h3>Heading 3</h3> <h4>Heading 4</h4> <h5>Heading 5</h5> <h6>Heading 6 (Bottom Level) </h6> </body> </html> Xxxxx dsfdsfdsf sadsdsad 2.1 sadsad 2.2 ddddd 2.2.1 xxxx sssss Don’t use the <h1>...<h6> to manipulate your font size. Use <font> tag Use <big>Test</big> or <small>Test</small>

28 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.

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.)

30 Physical Styles Examples: <b>Boldface</b>
<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>

32 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

33 Paragraph: To Break or No To Break
<NOBR>This is a paragraph. Spaces, line breaks, empty lines do not work in HTML documents.</NOBR> You need to use line break tag <br>.  This line has a line break. <BR>This line is followed by a horizontal line. <HR> <PRE>Another paragraph after <hr> the <hr></PRE> This is another paragraph with extra      space.

34 Horizontal Lines <HR>
<HTML> <HEAD> <TITLE>Horizontal Line </TITLE> </HEAD> <BODY> <HR> <!-- Netscape extensions --> <HR WIDTH=50% ALIGN=left SIZE=12> <HR WIDTH=50% ALIGN=center SIZE=3> <HR WIDTH=100% ALIGN=left SIZE=6 NOSHADE> </BODY> </HTML>

35 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).

36 Unordered Lists: <UL>, <LI>, </UL>

40 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)

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.

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 ®) Reference for special characters:

43 Document Meta Tags <TITLE></TITLE>: document title; goes in <HEAD> session. <BASE href="URL">: base reference, the full URL of the current document; goes in HEAD <HTML><HEAD> <META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso "> <META NAME="Author" CONTENT="Minder Chen"> <META NAME="GENERATOR" CONTENT="Mozilla/4.03 [en] [Netscape]"> <META NAME="Keywords" CONTENT="HTML, hypertext, aitc"> <META NAME="description" CONTENT="HTML tutorial for everyone"> <TITLE>test</TITLE></HEAD> For traditional Chinese: <META http-equiv="Content-Type" content="text/html; charset=big5" >

46 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.

47 Intra-document (Internal) Hypertext Links
Intra-document hyperlink links Section 1: aaa This is section 1 ... Back to the Table of Content Section 2: bbb This is section 2 Viewing area of the document Table of contents Section 1: aaa Section 2: bbb Section 3: ccc

48 Inter-document (External) Hypertext Links
... Link to document 2 Document2 ... Link to Section D of Doc3 A B C D an image map link an image link Document2 ... Section D Link to Document1 Toolbox Document Hammer ... Screw Driver ....

49 Hypertext Links Anchor: <a name="anchor"></a> Hyperlink:
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. Anchor: <a name="anchor"></a> Hyperlink: <a href="URL#anchor">Hot words</a>

50 Linking and Anchoring y.htm x.htm <html> … <html>
<body> <h1>Section 1</h1> <a href="#sec2"> Go to Section 2</a> <a name="sec2"></a> <h1>Section 2<h1> </body> </htm> <html> … <body> <a href="y.htm">Top of y</a> <a href="y.htm#sec2"> Section 2 of y</a> </body> </htm>

51 Example: Internal Link
<ul> <li> <a href="#minder">Minder Chen</a> <li>Bob Johnson </ul> <a name="minder"></a>Minder Chen<br> <br>

52 External Link Using Relative URL

56 Use a Relative URL Examples: Reasons to use relative URLs
<a href=" 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').

57 Document Directory Structure
Web document root y.htm (in the html folder) <a href="/html/y.htm">Root relative path</a> <a href="../y.htm">Document relative path</a> x.htm (<a href="x.htm">in the same folder</a>) 10_link.htm (Current Document) 10_test.htm (<a href="webpub/10_test.htm"></a>) oracle.htm (<a href="../../nvcc/oracle.htm"></a>

58 Relative URL

59 Links Between Documents
<html> <head> <title>Links with Relative URLs </title> </head> <body> <h2>Links with Relative URLs</a></h2> <h3>Links to another file on the same web site and in the same directory </h3> <ul> <li>Go to another document in the same directory <li><a href="10_link.htm">Go to the Anchors and Hyperlinks</a> <br> <li><xmp><a href="10_link.htm">Go to the Anchors and Hyperlinks</a> <br></xmp> </ul> <li>Go to an anchor of another document in the same directory <li><a href="10_link.htm#section2">Go to Section 2 of the Anchors and Hyperlinks</a> <br> <li><xmp><a href="10_link.htm#section2">Go to the Section 2 of the Anchors and Hyperlinks</a> <br></xmp> <h3>Links to another file on the same web site but in a different directory </h3> <li>Go to a document in a subdirectory directory of the current directory <li><a href="webpub/10_test.htm">Go to a 10_test.htm in the subdirectory /webpub under /tutor </a> <li><xmp><a href="webpub/10_test.htm">Go to 10_test.htm </a></xmp> in a subdirectory webpub under /tutor <li>Go to a document in a different directory <li><a href="../../nvcc/oracle.htm">Go to Oracle training</a> <li><xmp><a href="../../nvcc/oracle.htm">Go to Oracle training</a> </xmp> </body> </html>

60 Creating Links from Bookmarks in Netscape Composer
Drag-and-drop a bookmark item into the HTML document in the editing mode.

61 URL: Uniform Resource Locator
Uniform Resource Locator: A standard method of identifying any document or resource on the Internet. The port number can generally be omitted. The default http port name is Unless someone tells you otherwise, leave it out. In http, if filename is omitted, a default file such as index.html may be retrieved. Directory path name may be case sensitive.

62 Resource Types More examples: Resource types:
http: A file on a World Wide Web server ftp: A file on an anonymous FTP server mailto: Send an to an address file: A file on your local system gopher: A file on a Gopher server WAIS: A file on a WAIS server news: An Usenet newsgroup telnet: A connection to a Telnet-based service More examples: ftp://ftp.ncsa.uiuc.edu/Web gopher:make.up.something news:comp.databases.oracle telnet://osf1.gmu.edu Send an to <a Minder Chen</a>

63 Defining Absolute Hyperlinks: <a href="URL"> Hot words </a>

65 ALIGN

66 Download Image Files Click right mouse button on top of an image in a web page

67 Example Small Lion: <img src=" Big Lion: <img src=" Hot image using a thumb nail image to link to a larger image: <a href=" <img src=" </a>

68 Netscape Composer: Defining IMG Tag’s Attributes

69 <img> syntax <img src="slion.gif" align=left> Text float around the image that is placed on the left. <img src="slion.gif" align=right> <br clear="all | left | right | none"> Break the floating text. Clear="left": The next line begins at the nearest line at either margin following any floating objects.

70 Defining Image Link in Netscape Composer

71 Using IMG Tag Image Link: Advanced IMG Tag Attributes:
<IMG SRC="nvcclogo.gif" LOWSRC="low_resolution.gif" ALT="NVCC Logo" BORDER=0 HEIGHT=32 WIDTH=32 ALIGN=LEFT> Image Link: <A HREF=" <IMG SRC="AITCLOGO.gif"></A>

72 Image File Types GIF (pronounced as jiff): Graphics Interchange Format. Limited to 256 colors. Unisys owns the copyright of the LZW compression algorithm. GIF87 GIF89a supports transparency and interlacing Animated GIF: Use tools such as Microsoft GIF Animator at JPEG (pronounced jay-peg): Joint Photographic Experts Images. Good for photographic images. Use thumbnail for big image file. Use interlacing for big files. Cut down number of colors used to reduce file size. 8 bit/pixel resolution is 256 colors. Max 5 seconds download time per page.

73 Examples of Using Images

83 External Sounds and Animation
If you want to do the animation, video and audio, you need other multimedia applications development tools. You can use your own favorite applications tools to design your own graphics , audio, videos and so on by giving proper file extension.

84 Common MIME File Types for Multimedia Documents
The Netscape browser will be able to recognize the file followed by these extensions AIFF sound .au JPEG graphic .jpeg or .jpg MPEG movie .mpeg or .mpg PostScript document .ps QuickTime movie .mov WAVE sound .wav AIFF: Audio Interchange File Format MPEG: Moving Picture Experts Group 5-seconds of audio Size Format 36KB WAV 4KB RealAudio 14.4 8KB RealAudio 28.8

85 Configure Your Browser for Viewing Multimedia Documents
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.

86 Define Helper Apps: Edit / Preferences...

87 Linking to External Multimedia Files

120 <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"

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

122 One More Example <frameset rows="66%,33%"> <!--- Divide into 2 rows ---!> <frameset cols="33%,33%,33%"> <!--- Row 1: make 3 columns ----!> <frame src="A.html"> <!--- Column 1: A ---!> <frameset rows="50%,50%"> <!---Column 2: Divide into 2 rows: 1A and 1B---!> <frame src="B.html"> <!--- Column 2: Row 1A: B ---!> <frame src="D.html"> <!--- Column 2: Row 1B: D---!> </frameset> <frameset rows="50%,50%"> <!--- Column 3: Divide into 2 rows: 1A and 1B---!> <frame src="C.html"> <!--- Column 3: Row 1A: C ---!> <frame src="E.html"> <!--- Column 3: Row 1B: E ---!> </frameset> <!--- Close up Row 1 ---!> <frameset cols="33%,66%"> <!--- Row 2: make 2 columns ----!> <frame src="F.html"> <!--- Column 1: F ---!> <frame src="G.html"> <!--- Column 2: G ---!>

123 <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.

139 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

143 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.

Netscape 2.0+ and Internet Explore support client-side image map. Other browsers may ignore the usemap attribute in the <img> tag. For the same image map, we can include both client-side (honored by the browsers that can handle it) and server-side processing (for backward compatibility). <a href="/cgi-bin/imagemap/pics/bart.map"> <img src="/pics/bart3.gif" usemap="#map2" ismap ></a> <map name="map2"> <area shape=circle coords=…> <area shape=polygon coords=…> </map>

149 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: <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 character.
