Example 1
• A typical web page contains:– HTML instructions– Style sheets
• Colors, fonts, sizes, styles etc.
• Images, animated GIF images, objects, …
– Javascriptshtml_example.htm
36
Example 1 – HTML code (see example on StudySpace)
<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

Example 2 – Flash movies
• A Flash Movie that runs within a Web browser plug-in embedded with HTML– Flash Movies written separately– A Flash SWF file is downloaded along with a
Web page from a Web server, but the Flash itself runs on the user’s computer

Example 3 – Dynamic HTML
• Manipulating the HTML and browser with JavaScript– Rich interfaces and AJAX– Enabled web applications
Web applications: Google calendar
The Cloud
New type of services
Prosumer
Data portability
Intelligent web – APIs
Intelligent web – Mashups
New platforms
Game console integrationNew platforms
Android, Wave, Chrome OS, Friend connect
New platforms
Augmented reality + Profile
Mobile trends
1. Features that make sense in a Mobile phone.2. Move towards applications (away from pages.)
Learning, creating, testing and sharing
...in a fragmented ubiquitous digital landscape that builds on top of existing layers of technology.
From browser to server return
58
What is the Internet?
• A computer network is a collection of computers that can exchange data via a telecommunication mechanism
• An internet is a network of computer networks
• The Internet (capital ”I”) is one large, globally accessible internet
59
HTTP versus HTML
• HTTP governs how files move over the web• HTML defines structure of Web documents
Web Servere.g. www.kingston.ac.uk
User’s Web Browsere.g. k123456.kingston.ac.uk
The Internet
HTTP session
HTML docu-ments
60
Why is the Internet important?
• The third most important invention in the computing history– The Computer, the Microprocessor, The
Internet
• Worldwide communication, access to info, to people and business
• Easy to use
61
History
• 1960 ARPAnet• 1990 World Wide Web, Tim Berners-Lee created a
set of technologies that allowed information to be linked together through links in documents (HTML)
• 1992 Mark Andreessen created the first Web browser Mosaic
• 1994 World Wide Web Consortium
62
Web Browsers• Web browsers are software programs that allow users to
access certain types of Internet files in an interactive environment
• Microsoft’s Internet Explorer and Netscape’s Communicator
• The Uniform Resource Locator (URL) is the unique address associated with the Web page and is displayed in the browser window, e.g. (http://www.kingston.ac.uk/index.html)
• Navigation through hyperlinks which can reference other Web pages, e-mail addresses and files
63
Web Server
• A computer, running special software, which is always connected to the Internet
• Typing and URL in the Web browser or clicking in a link sends a request to the server that hosts this information
• The server sends back the requested files and displays them in the Web browser
64
Document Formatting
• WYSIWYG– “What You See Is What You Get”– Use visual tools to format the document
e.g. Word for Windows
• Mark-up Languages– Use special ‘codes’ to specify the functionality
of the content in a document
65
HTML
• Stands for Hyper-Text Mark-up Language• It is a Mark-up language and the files are
compiled and presented on demand, usually by a web browser
• However it is not a programming language– Note: there are Mark-up languages that are also
programming languages
66
HTML (cont…)
• HTML documents are plain text (not case sensitive) files with embedded markup codes (tags)
• Any simple text editor could be used to create and edit HTML file
• The file should be saved with extension .htm or .html
67
HTML versions
• Originally developed at CERN as part of the WWW project managed by Tim-Berners-Lee
• The first browser was Mosaic, by Marc Andreessen who went on to found Netscape
• The grey days of incompatibility followed until recently...
68
XHTML 1.1
• stands for EXtensible HyperText Markup Language
• Largely based on HTML 4.01
• Defines HTML as an XML application
69
What is a Tag?
• The mark-up ‘codes’ in HTML are called tags
• A tag may be used to describe an element of a list or the heading of a section
• Actually their functionality is much wider and we will attempt to introduce the most basic ones today
70
Just one Second !
• Is there any point in writing plain HTML when Microsoft Frontpage is out in the wild ?
• It produces very wasteful code
• It doesn’t always give you exactly what you want.
71
What do these tags look like? (1)
• Tag names are included in < >
• The text to be formatted is included in <tagname> text </tagname>
• Tags can be nested <b><i>text</i></b>
72
What do these tags look like?
• They may also have attributes<img id="flower" />
• Tags must always have a matching closing tag
73
Structure of a Tag
<p id="title">Welcome to CO1052</p>
tag attribute attribute endname name value tag
74
The Mother of all Tags
• Tags in XHTML are case sensitive– BUT not in HTML
• The most basic tag is the one that specifies the document type.
• The whole of an HTML document must be included between
<html>and
</html>
75
The Document Type
• To adhere to the XHTML 1.1 standard, the first line of the document must be the appropriate document declaration
e.g. (see next week lecture)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
76
Inside the document
• A document must have a head and title element given by the nested tags:
<head><title>Here goes the title</title>
</head>
• The head section is followed by the body <body> everything happens here </body> section.
• The body is where everything happens
77
HTML/XHTML Document - example
<!DOCTYPE html PUBLIC"-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<title> Example of a title </title>
</head>
<body>
<h1>This is an example of h1 heading</h1>
</body>
</html>
78
So How to Type your HTML Code then?
• Use simple ‘text’ editors, such as notepad– And don’t forget to save file with file extension
.htm or .html
• Use ‘HTML Editor’ such as HTML-Kit• Use WYSIWYG authoring software such as
Dreamweaver from Macromedia
79
Using notepad
• Follow start > All programs > Accessories > Notepad
