21. Dr. Chen, Management Information Systems - HTML 21 What Is Hypertext Markup Language? Web pages are created using Hypertext Markup Language (HTML), which is an authoring language used to create documents for the World Wide Web HTML uses a set of special instructions called tags or markup to define the structure and layout of a Web document and specify how the page is displayed in a browser HTML is platform independent, meaning you can create, or code, an HTML file on one type of computer and then use a browser on another type of computer to view that file as a Web page 21

22. Dr. Chen, Management Information Systems - HTML 22 What Is Hypertext Markup Language? 22

23. Dr. Chen, Management Information Systems - HTML 23 HTML Elements 23

24. Dr. Chen, Management Information Systems - HTML 24 HTML Coding Practices 24

25. Dr. Chen, Management Information Systems - HTML 25 A Simple Table and HTML Structure of a Table The layout of a graphical table two rows two columns beginning of the table structure first row of two in the table end of the table structure Second row of two in the table

26. Dr. Chen, Management Information Systems - HTML 26 A Simple Table and HTML Structure of a Table The layout of a graphical table two rows two columns beginning of the table structure first row of two in the table end of the table structure table cells You do not need to indent the tags or place them on separate lines, but you may find it easier to interpret your code if you do so. After the table structure is in place, you’re ready to add the text for each cell. Second row of two in the table First Cell Second Cell Third Cell Fourth Cell We will study more about how to create tables in chapter 4.

27. Dr. Chen, Management Information Systems - HTML 27 HTML Versions HTML has gone through several versions, each of which expands the capabilities of HTML The most recent version of HTML is HTML 4.01, although most browsers still support HTML versions 3.2 and 2.0 27

28. Dr. Chen, Management Information Systems - HTML 28 Document Object Model (DOM) Document Object Model (DOM) describes a combination of HTML tags, CSS, and a scripting language such as JavaScript DOM allows JavaScript and other languages to manipulate the structure of the underlying document to create interactive, animated Web pages Have you learned (or implemented) any?

29. Dr. Chen, Management Information Systems - HTML 29 Cascading Style Sheets Cascading Style Sheets (CSS) allows you to specify the style for an element within a single Web page or throughout an entire Web site We start using CSS in Chapter 2 and will learn more in chapter 7. See next slide for CSS example

31. Dr. Chen, Management Information Systems - HTML 31 Extensible Hypertext Markup Language (XHTML) Extensible Markup Language (XML) is a markup language that uses tags to describe the structure and content of a document, not the format Extensible Hypertext Markup Language (XHTML) is a reformulation of HTML formatting so it conforms to XML structure and content rules 31

33. Dr. Chen, Management Information Systems - HTML 33 Tools for Creating HTML Documents A text editor (e.g., Notepad or Notepad++) is a program that allows a user to enter, change, save, and print text, such as HTML An HTML text editor is a program that provides basic text editing functions, as well as more advanced features such as color-coding for various HTML tags, menus to insert HTML tags, and spell checkers An HTML object editor, such as Eiffel Software object editor, provides the additional functionality of an outline editor that allows you to expand and collapse HTML objects and properties, edit parameters, and view graphics attached to the expanded objects A WYSIWYG editor is a program that provides a graphical user interface that allows a developer to preview the Web page during its development 33
