  3. 3. INDEX <ul><li>Introduction to HTML </li></ul><ul><li>2. Importance of HTML </li></ul><ul><li>3. Understanding HTML elements </li></ul><ul><li>4. Overall structure of an HTML document </li></ul><ul><li>5. Creating list & inserting images </li></ul><ul><li>6. Hyperlinks & anchors </li></ul><ul><li>7. Conclusion </li></ul>
  4. 4. Introduction to HTML <ul><li>HTML = H yper T ext M arkup L anguage </li></ul><ul><li>HYPERTEXT – An ordinary text that has some ‘extra’ features such as formatting, images, multimedia etc. </li></ul><ul><li>MARKUP - process of adding ‘extra’ features to ordinary text. </li></ul><ul><li>LANGUAGE - Means it has its own syntax, slang and rules for proper communication. </li></ul>
  5. 5. Short History <ul><li>Initially SGML (Standard Generalised Mark-up Language) – A high level language was used by Department of Defense (DoD). </li></ul><ul><li>Later HTML developed as a subset of SGML. </li></ul><ul><li>Advantages of HTML: </li></ul><ul><li>-- simple </li></ul><ul><li>-- Best suited for internet transmission. </li></ul><ul><li>-- lets you create page that can be read on web. </li></ul>
  6. 6. Tools for Web Publishing <ul><li>The most basic element of any HTML page is ASCII text. </li></ul><ul><li>HTML pages, while they include the .htm or .html file extensions, are simply ASCII text files. </li></ul><ul><li>HTML Editor- Any program that generates ASCII text files. </li></ul><ul><li>e.g.: A word processor or Microsoft word. </li></ul>
  7. 7. Importance of HTML <ul><li>1. Used to display any type of document on the host computer. </li></ul><ul><li>2. A versatile language and can be used on any platform. </li></ul><ul><li>3. Used to make the text look attractive. </li></ul><ul><li>4. Can link one document with another. </li></ul>
  8. 8. Steps to Creating an HTML Document <ul><li>Open a text editor. </li></ul><ul><li>Create your HTML document </li></ul><ul><ul><ul><li>Head - not displayed with body </li></ul></ul></ul><ul><ul><ul><li>Body </li></ul></ul></ul><ul><li>Save the HTML (extension of .htm or .html) </li></ul><ul><li>Display your HTML document in WWW browser window (Open File rather than Open Location). </li></ul><ul><li>Check your work and modify as necessary. </li></ul><ul><li>Place it on the Web. </li></ul>
  9. 9. NOTE:- <ul><li>If we create an HTML page in a word processor THEN we use the Save As command to save it as an ASCII text file. </li></ul><ul><li>For checking on the appearance of the web page we have created we need a web browser. </li></ul><ul><li>A web browser should have the ability to load, locate pages from the hard drive. </li></ul>
  10. 10. Introduction to HTML <ul><li>A web page is made up of elements, each of which is defined by an HTML code or tag. </li></ul><ul><li>Document Tags :- The tags that are required for every HTML page we create. </li></ul><ul><li>HTML document has two distinct parts: </li></ul><ul><li>1. A Head </li></ul><ul><li>2. A Body </li></ul><ul><li>Between these two tags, we enter the rest of text and graphics. </li></ul>
  11. 11. Understanding Tags <ul><li>The HTML tags include < and > symbol on either side of the tag’s command. </li></ul><ul><li>If the symbols are not used then the browser will assume the commands as text. </li></ul><ul><li>HTML elements can be categorized as : </li></ul><ul><li>Container elements </li></ul><ul><li>Empty elements </li></ul>
  12. 12. HOW TAGS WORK?? <ul><li>The first part of the tag <tag name> turns the tag on. </li></ul><ul><li>The ending part of the tag, </tag name>, contains the &quot;/&quot; slash character. </li></ul><ul><li>This &quot;/&quot; slash tells a WWW browser to stop tagging the text. Many HTML tags are paired this way. Think of the tag as a container. </li></ul><ul><li>If you forget the backslash, a WWW browser will continue the tag for the rest of the text in your document,producing undesirable results. </li></ul>
  13. 13. HTML Element <ul><li>A container element. </li></ul><ul><li>Identifies the document as an HTML document. </li></ul><ul><li>The <HTML> element delimits the beginning and end of HTML document. </li></ul><ul><li>Contains only the <HEAD> and <BODY> elements. </li></ul><ul><li>Eg. <HTML> </li></ul><ul><li>: </li></ul><ul><li>: </li></ul><ul><li></HTML> </li></ul>
  14. 14. HEAD Element <ul><li>A container element. </li></ul><ul><li>Contains information about the document. </li></ul><ul><li>TITLE element is included in HEAD element. </li></ul><ul><li>-> TITLE element is a container element. </li></ul><ul><li>->used to provide title of the document. </li></ul><ul><li>Eg. </li></ul><ul><li><HTML> </li></ul><ul><li><HEAD> </li></ul><ul><li><TITLE> This is my first page </TITLE> </li></ul><ul><li></HEAD> </li></ul><ul><li></HTML> </li></ul>
  15. 15. BODY Element <ul><li>A container element. </li></ul><ul><li>The BODY element contains all the text and images that make up the page. It also contains HTML elements that provide the control and formatting of the page. </li></ul><ul><li>Eg: <BODY> </li></ul><ul><ul><ul><li>------- </li></ul></ul></ul><ul><ul><ul><li>------- </li></ul></ul></ul><ul><ul><ul><li></BODY> </li></ul></ul></ul>

  43. 43. Making Lists <ul><li>HTML supports several types of list elements that should be included within the BODY element of the document. </li></ul><ul><li>The tag used to indicate an item is LI. </li></ul><ul><li><LI> tag is an empty element. </li></ul><ul><li>List can be of two types: </li></ul><ul><li>Ordered list </li></ul><ul><li>Unordered list </li></ul>
  44. 44. Conti… <ul><li>Ordered list(OL): </li></ul><ul><li>Syntax: </li></ul><ul><li><OL START =“VALUE” </li></ul><ul><li>TYPE= “A”/“a”/”i”/”I”/”1”> </li></ul><ul><li>---------- </li></ul><ul><li></OL> </li></ul><ul><li>Where, </li></ul><ul><li>start=“value” indicates the starting number for the list. </li></ul><ul><li>Type attribute defines the type of numbering sequence. </li></ul>

  50. 50. INSERTING IMAGES <ul><li>IMG Element : </li></ul><ul><li>The IMG tag specifies an image to be displayed in an HTML document. </li></ul><ul><li>It is an empty element. </li></ul><ul><li>Syntax: </li></ul><ul><li><IMG </li></ul><ul><li>SRC = IMAGE_URL </li></ul><ul><li>ALIGN= ALIGNMENT </li></ul><ul><li>BORDER= BORDER WIDTH_VALUE </li></ul><ul><li>HEIGHT= HEIGHT_VALUE </li></ul><ul><li>WIDTH= WIDTH_VALUE </li></ul><ul><li>ALT = TEXT </li></ul><ul><li>> </li></ul>
  51. 51. DESCRIPTION <ul><li>SRC : The value is the URL of the image to be displayed. </li></ul><ul><li>Eg; <IMG SRC = “CLOUDS.GIF”> </li></ul><ul><li>ALIGN : Used to determine the vertical alignment of the text adjacent to the image. </li></ul><ul><li>By default navigator uses BOTTOM. </li></ul><ul><li>Eg: <IMG SRC = “CLOUDS.GIF” ALIGN = “LEFT”> </li></ul><ul><li><IMG SRC = “CLOUDS.GIF” ALIGN = “RIGHT”> </li></ul><ul><li><IMG SRC = “CLOUDS.GIF” ALIGN = “BOTTOM”> </li></ul><ul><li><IMG SRC = “CLOUDS.GIF” ALIGN = “TOP”> </li></ul><ul><li>BORDER : Specifies the width of a border around the image. The value must be a positive integer. </li></ul><ul><li>Eg: <IMG SRC = CLODS.GIF” BORDER = “3”> </li></ul>
  52. 52. CONTI… <ul><li>HEIGHT : Specifies the height of an image either in the form of an integer or as a percentage of the height of the window. </li></ul><ul><li>Eg: <IMG SRC =“ CLOUDS.GIF” BORDER =“3” HEIGHT = 20%> </li></ul><ul><li>WIDTH : Specifies the width of an image either in the form of an integer or as a percentage of the width of the window. </li></ul><ul><li>Eg: <IMG SRC= “SKY.GIF” BORDER= “3” HEIGHT= 20% WIDTH= 50%> </li></ul><ul><li>ALT : Used to give alternate text that will be displayed in place of the image. </li></ul><ul><li>USAGE: This is required when the user needs to stop the display of images while retrieving a document in order to make the retrieval faster or when the browser does not support graphics. </li></ul><ul><li>Eg: <IMG SRC=“SKY.GIF” ALT= “CLOUDS IN THE SKY”> </li></ul>
  53. 53. EXAMPLE <ul><li><html> </li></ul><ul><li><body> </li></ul><ul><li><img </li></ul><ul><li> border=&quot;0&quot; </li></ul><ul><li>src=&quot;/images/google.jpg&quot; </li></ul><ul><li>width=&quot;304&quot; </li></ul><ul><li>height=&quot;228“ </li></ul><ul><li> > </li></ul><ul><li></body> </li></ul><ul><li></html> </li></ul>
  54. 54.
  56. 56. INTRODUCTION <ul><li>ANCHOR ELEMENT : </li></ul><ul><li>The Anchor element <A> marks the text as a hypertext link, that the user can click to display an anchor as a document. </li></ul><ul><li>The <A> or anchor tag is used for creating hypertext links. This tag is a container tag and requires </A> to mark the end of the text, images. </li></ul><ul><li>Syntax: </li></ul><ul><ul><ul><li><A HREF =“URL” > TEXT DESCRIBING LINK </A> </li></ul></ul></ul><ul><ul><ul><li>DESC: </li></ul></ul></ul><ul><ul><ul><li>If the above statement is displayed in a browser, the words TEXT DESCRIBING LINK would appear underlined and in another color to indicate that clicking that text starts the execution of the hypertext link. </li></ul></ul></ul>
  57. 57. CONTI… <ul><li>HREF </li></ul><ul><li>The HREF attribute make the text enclosed between the opening <A> and closing </A> anchor elements as hypertext . </li></ul><ul><li>If the user selects this hypertext the control moves to the document specified by the value of the attribute. </li></ul><ul><li>Eg: <A HREF = “SHAPE.HTM”> CLICK HERE </A> </li></ul><ul><li>In the above example selecting the hypertext CLICK HERE takes the reader to the document named SHAPE.HTM </li></ul><ul><li>SELECTION LINKS : Create links to other parts of the same document in which link appears. </li></ul><ul><li>This requires two instances of the anchor tag- one that serves as a hypertext link and another that acts as a reference point for that link. </li></ul>
  58. 58. CONTI…. <ul><li>FOR EXAMPLE: </li></ul><ul><li><A HREF = “#SECTION-NAME”> Link to another section of same document </A> </li></ul><ul><li><A NAME = “ SECTION-NAME”> New Section </A> </li></ul><ul><li>The anchor tag that creates the hyperlink is similar to the anchor tag that we have done previously. </li></ul><ul><li>The only difference is that it begins with (#) sign in HREF text. </li></ul><ul><li>This sign tells the anchor that it is looking for a section within the current document. </li></ul><ul><li>The NAME attribute is used to create the actual section within the current HTML document. </li></ul><ul><li>NAME is like an internal reference; w/o it, though, the link would not work. The NAME text is case sensitive. </li></ul>
  60. 60. Source Document <ul><li><html> </li></ul><ul><li><head> </li></ul><ul><li><title>Source Document</title> </li></ul><ul><li></head> </li></ul><ul><li><body> </li></ul><ul><li><a href=&quot;target.html#danger&quot;> </li></ul><ul><li>Better look here </li></ul><ul><li></a> </li></ul><ul><li></body> </li></ul><ul><li></html </li></ul>

  62. 62.
  63. 63. COMMON TAGS USED <ul><li><HTML> </HTML> Opens and closes the HTML document. </li></ul><ul><li><title> </title> This is the title of your page and will appear at the top of your browser’s window. </li></ul><ul><li><h1> </h1> <h5> </h5> Header sizes for titles and larger text formats. Or specify font size: <font size=“4”> </font> </li></ul><ul><li><img src=“filename.gif”> </li></ul><ul><ul><li>Sources an image file and needs no closing tag. </li></ul></ul>
  64. 64. COMMON TAGS USED <ul><li><a href=“filename.html”> Place URL </a> </li></ul><ul><ul><li>Links text or images to the designated file. </li></ul></ul><ul><li><b> text </b> Bold text. </li></ul><ul><li><i> text </i> Italic text. </li></ul><ul><li><u> text </u> Underline text. </li></ul><ul><li><br> (no closing) Line break. </li></ul><ul><li><hr> (no closing) Horizontal line. </li></ul>
  65. 65. POINTS TO REMEMBER <ul><li>There are two kinds of HTML elements used to construct an HTML document. These are container and empty elements. </li></ul><ul><li>An HTML document should start with a container HTML tag and end with a closing HTML tag. </li></ul><ul><li>The HTML tags are not case sensitive. </li></ul><ul><li>The image to be copied should have an extension GIF or JPEG. </li></ul><ul><li>The items in a list will be displayed in a bulleted form if TYPE attribute is not given. </li></ul>
  66. 66. POINTS TO REMEMBER <ul><li>There are five ways in which we can number the list. </li></ul><ul><li>The IMG tag specifies an image to be displayed in a HTML document. </li></ul><ul><li>The extension of the image file should be either GIF or JPEG. </li></ul><ul><li>The image can be aligned as- left, right, top, bottom margin. </li></ul><ul><li>An Anchor element may not enclose another Anchor element. </li></ul><ul><li>An image can also be used as an hyperlink. </li></ul>
