XHTML and the Development of HTML 5
Existence of several versions of HTML (deprecation) XHTML (Extensible Hypertext Markup Language) is a stricter version of HTML and is designed to confront some of the problems associated with the different and competing versions of HTML XHTML is also designed to better integrate HTML with other markup languages such as XML

Tools for Creating HTML Documents
Basic text editor such as Windows Notepad (PC) or TextEdit (Mac). Other software programs that enable you to create documents in different formats, such as Microsoft Word or Adobe Acrobat, include tools to convert their documents into HTML for quick and easy publishing on the Web Web publishing software manages all of the code and extended features of your site

Entering Elements and Attributes
An HTML document is composed of elements that represent distinct items in the Web page, such as a paragraph, the page heading, or even the entire body of the page itself Elements are marked by one or more tags A two-sided tag is a tag that contains some document content. General syntax for a two-sided tag: <element>content</element>
7
Marking Elements with Tags
A two-sided tag’s opening tag (<p>) and closing tag (</p>) should completely enclose its content Elements can contain other elements Tags cannot overlap <p>CBIS 3219: Web Development</p>
8
Adding an Attribute to an Element
To add an element attribute, use the format <element attribute1=”value1” attribute2=”value2” ...>content</element> where attribute1, attribute2, etc. are the names of attributes associated with the element, and value1, value2, etc. are the values of those attributes. <p align =“left”>CBIS 3219: Web Development</p>

Exploring the Structure of an HTML File
<html> <head> head content </head> <body> body content </body> </html> Practice 3.
10
HTML is like a Sandwich???
11
Practice Create a new html page and save it as basic.html
Create the root html element and nest the head and body elements within it.
12
Document Type Declaration
Prior to the opening <html> tag, many HTML files also include a Document Type Declaration, or doctype, to indicate the type of markup language used in the document. Doctype for HTML 4.01: <!DOCTYPE HTML PUBLIC “-//W3C//DTD HTML 4.01/EN” “ Doctype for XHTML: <!DOCTYPE HTML PUBLIC “-//W3C//DTD XHTML 1.0 Strict//EN” “ strict.dtd”> Doctype for HTML5: <!DOCTYPE html> Practice 2
13
Practice Add the doctype for HTML5 to the basic page.
14
Head Element Page Title (appears in the title bar of the browser)
Syntax: <title>document title</title> Example: <title>Shop clothes for women, men, maternity, baby, and kids | Gap </title> Practice 6 Used by search engines when compiling an index of search results.
15
Practice Set the page title of the Basic page to The J-Prop Shop – Special This Month.
16
Adding Comments Purpose: Explain your code to yourself or others.
Comments are not displayed in the browser. Comments can be spread over several lines if necessary. Syntax: <!-- comment --> Example: <!– The doctype of this document indicates that HTML5 is used --> Practice 4
17
Practice Within the head element, insert the comment The J-Prop Shop
