Defining Web Page Structure
• To create an HTML document, you use a text editor to enter information about the structure of the Web page.
• Before you begin entering the content, you must start by entering texts that define the overall structure of the Web page.
• You do this by inserting a <!DOCTYPE> tag and five tags <html>, <head>, <meta />, <title> and <body>.
• The <!DOCTYPE> tag is used to tell the browser which HTML or XHTML version and type the document uses.
Chapter 2: Creating and Editing a Web Page 7
Defining the HTML Document
• The first set of tags beyond the <!DOCTYPE> tag, <html> and /html> indicates the start and end of and HTML document.
• The Header – the next set of tags <head> and </head>, contains the Web page title and other document header information.
• The Body - the final set of tags, <body> and </body>, contains the main content of the Web page. All text , images, links and other content are contained within this final set of tags.
