2 Definitions W W W – World Wide Web. HTML – HyperText Markup Language – The Language of Web Pages on the World Wide Web. HTML is a text formatting language. URL – Uniform Resource Locator. Browser – A software program which is used to show web pages.
3 “Normal text” surrounded by bracketed tags that tell browsers how to display web pages Pages end with “.htm” or “.html” HTML Editor – A word processor that has been specialized to make the writing of HTML documents more effortless.
4 Tags Codes enclosed in brackets Usually paired <TITLE>My Web Page</TITLE> Not case sensitive <TITLE> = <title> = <TITLE>
5 Choosing Text Editor There are many different programs that you can use to create web documents. HTML Editors enable users to create documents quickly and easily by pushing a few buttons. Instead of entering all of the HTML codes by hand. These programs will generate the HTML Source Code for you.
6 Choosing Text Editor HTML Editors are excellent tools for experienced web developers; however; it is important that you learn and understand the HTML language so that you can edit code and fix “bugs” in your pages. For this Course, we will focus on using the standard Microsoft Windows text editors, NotePad. We may use also textpad.
7 Starting NotePad NotePad is the standard text editor that comes with the microsoft windows operating system. To start NotePad in windows 9x or XP follow the steps bellow: Click on the “Start” button located on your Windows task bar. Click on “Programs” and then click on the directory menu labeled “Accessories”. Locate the shortcut “NotePad” and click the shortcut once.
8 HTML Page Creation & Editing In this chapter you will learn to create HTML pages with a standard text editor. Objectives Upon completing this section, you should be able to 1. Choose a Text Editor. 2. Create a Basic Starting Document. 3. Understand and set Document Properties. 4. View Your Results in a Browser.
9 Creating a Basic Starting Document <HTML> <HEAD> <TITLE>Al al-Bayt University</TITLE> </HEAD> <BODY> This is what is displayed. </BODY> </HTML>
10 Creating a Basic Starting Document The HEAD of your document point to above window part. The TITLE of your document appears in the very top line of the user’s browser. If the user chooses to “Bookmark” your page or save as a “Favorite”; it is the TITLE that is added to the list. The text in your TITLE should be as descriptive as possible because this is what many search engines, on the internet, use for indexing your site.
11 Setting Document Properties Document properties are controlled by attributes of the BODY element. For example, there are color settings for the background color of the page, the document’s text and different states of links.
12 Color Codes Colors are set using “RGB” color codes, which are, represented as hexadecimal values. Each 2-digit section of the code represents the amount, in sequence, of red, green or blue that forms the color. For example, a RGB value with 00 as the first two digits has no red in the color.
13 16 Basic Colors
14 Color Codes WHITE BLACK RED GREEN BLUE MAGENTA CYAN YELLOW AQUAMARINE BAKER’S CHOCOLATE VIOLET BRASS COPPER PINK ORANGE #FFFFFF #000000 #FF0000 #00FF00 #0000FF #FF00FF #00FFFF #FFFF00 #70DB93 #5C3317 #9F5F9F #B5A642 #B87333 #FF6EC7 #FF7F00
15 The Body Element The BODY element of a web page is an important element in regards to the page’s appearance. Here are the attributes of the BODY tag to control all the levels: TEXT="#RRGGBB" to change the color of all the text on the page (full page text color.) This element contains information about the page’s background color, the background image, as well as the text and link colors.
16 Background Color It is very common to see web pages with their background color set to white or some other colors. To set your document’s background color, you need to edit the <BODY> element by adding the BGCOLOR attribute. The following example will display a document with a white background color: <BODY BGCOLOR=“#FFFFFF”></BODY>
17 TEXT Color The TEXT attribute is used to control the color of all the normal text in the document. The default color for text is black. The TEXT attribute would be added as follows: <BODY BGCOLOR=“#FFFFFF” TEXT=“#FF0000”></BODY> In this example the document’s page color is white and the text would be red.
18 LINK, VLINK, and ALINK These attributes control the colors of the different link states: 1. LINK – initial appearance – default = Blue. 2. VLINK – visited link – default = Purple. 3. ALINK –active link being clicked–default= Yellow. The Format for setting these attributes is: <BODY BGCOLOR=“#FFFFFF” TEXT=“#FF0000” LINK=“#0000FF” VLINK=“#FF00FF” ALINK=“FFFF00”> </BODY>
19 Using Image Background The BODY element also gives you ability of setting an image as the document’s background. An example of a background image’s HTML code is as follows: <BODY BACKGROUND=“hi.gif” BGCOLOR=“#FFFFFF”></BODY>
20 Previewing Your Work Once you have created your basic starting document and set your document properties it is a good idea to save your file. To save a file, in NotePad, follow these steps: Locate and click on the menu called “File”. Select the option under File Menu labeled “Save As”. In the “File Name” text box, type in the entire name of your file (including the extension name .html).
21 Edit, Save and View Cycle To preview Your Work, open a web browser and do the following: Click on the menu labeled “File”. Locate the menu option, “Open”.
22 Edit, Save and View Cycle In the “Open” dialog box, click on the “Browse” button and locate your web document. Click “OK” once you have selected your file. The web browser will load the same document but with the new revisions. This process is the Edit, Save and View Cycle.
23 Headings, Paragraphs, Breaks & Horizontal Rules In this chapter you will add headings to your page, insert paragraphs, add some breaks, and add horizontal rules. Objectives Upon completing this section, you should be able to List and describe the different Heading elements. Use Paragraphs to add text to a document. Insert breaks where necessary. Add a Horizontal Rule.
24 Headings, <Hx> </Hx> Inside the BODY element, heading elements H1 through H6 are generally used for major divisions of the document. Headings are permitted to appear in any order, but you will obtain the best results when your documents are displayed in a browser if you follow these guidelines: H1: should be used as the highest level of heading, H2 as the next highest, and so forth. You should not skip heading levels: e.g., an H3 should not appear after an H1, unless there is an H2 between them.
25 Headings, <Hx> </Hx> <HTML> <HEAD> <TITLE> Example Page</TITLE> </HEAD> <BODY> <H1> Heading 1 </H1> <H2> Heading 2 </H2> <H3> Heading 3 </H3> <H4> Heading 4 </H4> <H5> Heading 5 </H5> <H6> Heading 6 </H6> </BODY> </HTML> Heading 1 Heading 2 Heading 3 Heading 4 Heading 5 Heading 6
26 Paragraphs, <P> </P> Paragraphs allow you to add text to a document in such a way that it will automatically adjust the end of line to suite the window size of the browser in which it is being displayed. Each line of text will stretch the entire length of the window.
27 Paragraphs, <P> </P> <HTML><HEAD> <TITLE> Example Page</TITLE> </HEAD> <BODY></H1> Heading 1 </H1> <P> Paragraph 1, ….</P> <H2> Heading 2 </H2> <P> Paragraph 2, ….</P> <H3> Heading 3 </H3> <P> Paragraph 3, ….</P> <H4> Heading 4 </H4> <P> Paragraph 4, ….</P> <H5> Heading 5 </H5> <P> Paragraph 5, ….</P> <H6> Heading 6</H6> <P> Paragraph 6, ….</P> </BODY></HTML> Heading 1 Paragraph 1,…. Heading 2 Paragraph 2,…. Heading 3 Paragraph 3,…. Heading 4 Paragraph 4,…. Heading 5 Paragraph 5,…. Heading 6 Paragraph 6,….
28 Break, <BR> Line breaks allow you to decide where the text will break on a line or continue to the end of the window. A <BR> is an empty Element, meaning that it may contain attributes but it does not contain content. The <BR> element does not have a closing tag.
29 Break, <BR> <HTML> <HEAD> <TITLE> Example Page</TITLE> </HEAD> <BODY> <H1> Heading 1 </H1> <P>Paragraph 1, <BR> Line 2 <BR> Line 3 <BR>…. </P> </BODY> </HTML> Heading 1 Paragraph 1,…. Line 2 Line 3 ….
30 Horizontal Rule, <HR> The <HR> element causes the browser to display a horizontal line (rule) in your document. <HR> does not use a closing tag, </HR>.
31 Horizontal Rule, <HR>
32 Horizontal Rule, <HR> <HTML> <HEAD> <TITLE> Example Page</TITLE> </HEAD> <BODY> <H1> Heading 1 </H1> <P>Paragraph 1, <BR> Line 2 <BR> <HR>Line 3 <BR> </P> </BODY> </HTML> Heading 1 Paragraph 1,…. Line 2 ___________________________ Line 3

Objectives Upon completing this section, you should be able to Change the color and size of your text. Use Common Character Formatting Elements. Align your text. Add special characters. Use other character formatting elements.
34 Bold, Italic and other Character Formatting Elements <FONT SIZE=“+2”> Two sizes bigger</FONT> The size attribute can be set as an absolute value from 1 to 7 or as a relative value using the “+” or “-” sign. Normal text size is 3 (from -2 to +4). <B> Bold </B> <I> Italic </I> <U> Underline </U> Color = “#RRGGBB” The COLOR attribute of the FONT element.

Spaces and line breaks are supported without additional elements or special characters.
35 Bold, Italic and other Character Formatting Elements <EM> Emphasis </EM> Browsers usually display this as italics. <STRONG> STRONG </STRONG> Browsers display this as bold. <TT> TELETYPE </TT> Text is displayed in a mono-spaced font. A typewriter text, e.g. fixed-width font. <CITE> Citation </CITE> represents a document citation (italics). For titles of books, films, etc. Typically displayed in italics. (A Beginner's Guide to HTML)

37 Alignment Some elements have attributes for alignment (ALIGN) e.g. Headings, Paragraphs and Horizontal Rules. The Three alignment values are : LEFT, RIGHT, CENTER. <CENTER></CENTER> Will center elements.
38 Alignment <DIV ALIGN=“value”></DIV> Represents a division in the document and can contain most other element type. The alignment attribute of the DIV element is well supported. <TABLE></TABLE> Inside a TABLE, alignment can be set for each individual cell.
39 Special Characters & Symbols These Characters are recognized in HTML as they begin with an ampersand and end with with a semi-colon e.g. &value; The value will either be an entity name or a standard ASCII character number. They are called escape sequences. The next table represents some of the more commonly used special characters. For a comprehensive listing, visit the W3C’s section on special characters at: http://www.w3.org/MarkUp/HTMLPlus/htmlplus_13.html
40 Special Characters & Symbols
41 Additional escape sequences support accented characters, such as: ö a lowercase o with an umlaut: o ñ a lowercase n with a tilde: n È an uppercase E with a grave accent: E NOTE: Unlike the rest of HTML, the escape sequences are case sensitive. You cannot, for instance, use < instead of <. Special Characters & Symbols
42 Additional Character Formatting Elements <STRIKE> strike-through text</STRIKE> DEL is used for STRIKE at the latest browsers <BIG> places text in a big font</BIG> <SMALL> places text in a small font</SMALL> <SUB> places text in subscript position </SUB> <SUP> places text in superscript style position </SUP>
43 Example <P><STRIKE> strike-through text </STRIKE></BR> <BIG>places text in a big font </BIG><BR> <SMALL> places text in a small font</SMALL><BR> <SUB> places text in subscript position </SUB> Normal <SUP> places text in superscript style position </SUP><BR> </P>
44 Lists In this chapter you will learn how to create a variety of lists. Objectives Upon completing this section, you should be able to Create an unordered list. Create an ordered list. Create a defined list. Nest Lists.
45 List Elements HTML supplies several list elements. Most list elements are composed of one or more <LI> (List Item) elements. 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. <UL> <LI> List item …</LI> <LI> List item …</LI> </UL> List item … List item …
46 List Elements You have the choice of three bullet types: disc(default), circle, square. These are controlled in Netscape Navigator by the “TYPE” attribute for the <UL> element. <UL TYPE=“square”> <LI> List item …</LI> <LI> List item …</LI> <LI> List item …</LI> </UL> List item … List item … List item …
47 List Elements OL: Ordered List. Items in this list are numbered automatically by the browser. <OL> <LI> List item …</LI> <LI> List item …</LI> <LI> List item …</LI> </OL> List item … List item … List item You have the choice of setting the TYPE Attribute to one of five numbering styles.
48 List Elements
49 List Elements You can specify a starting number for an ordered list. <OL TYPE =“i”> <LI> List item …</LI> <LI> List item …</LI> </OL> <P> text ….</P> <OL TYPE=“i” START=“3”> <LI> List item …</LI> </OL>
50 List Elements List item … List item … Text …. List item …
51 List Elements DL: Definition List. This kind of list is different from the others. Each item in a DL consists of one or more Definition Terms (DT elements), followed by one or more Definition Description (DD elements). <DL> <DT> HTML </DT> <DD> Hyper Text Markup Language </DD> <DT> DOG </DT> <DD> A human’s best friend!</DD> </DL> HTML Hyper Text Markup Language DOG A human’s best friend!
52 Nesting Lists You can nest lists by inserting a UL, OL, etc., inside a list item (LI). EXample <UL TYPE = “square”> <LI> List item …</LI> <LI> List item … <OL TYPE=“i” START=“3”> <LI> List item …</LI> <LI> List item …</LI> <LI> List item …</LI> <LI> List item …</LI> <LI> List item …</LI> </OL> </LI> <LI> List item …</LI> </UL>
53 <H1 ALIGN="CENTER">SAFETY TIPS FOR CANOEISTS</H1><OL TYPE=“a” START=“2”><LI>Be able to swim </LI> <LI>Wear a life jacket at all times </LI><LI>Don't stand up or move around. If canoe tips, <UL><LI>Hang on to the canoe </LI> <LI>Use the canoe for support and </LI> <LI>Swim to shore</UL> </LI> <LI>Don't overexert yourself </LI> <LI>Use a bow light at night </LI> </OL> What will be the output?
54 The output….
