INTRODUCTION

Web development is a broad term for the work involved in developing a web site for the Internet (World Wide Web) or an intranet (a private network). Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services. A more comprehensive list of tasks to which web development commonly refers, may include web design, web content development, client liaison, client-side/server-side scripting, web server and network security configuration, and e-commerce development. Among web professionals, "web development" usually refers to the main non-design aspects of building web sites: writing markup and coding.

HISTORY OF WORLD WIDE WEB

The web is a wonderful place. It connects people from across the globe, keeps us updated with our friends and family, and creates revolutions never before seen in our lifetime. It has certainly come a long way since its humble beginnings back in the early 1980's.

Many people refer to them as the same thing, but in fact, although the end result is the common perception of most everyday users, they are very different. The internet is a series of huge computer networks that allows many computers to connect and communicate with each other globally. Upon the internet reside a series of languages which allow information to travel between computers. These are known as protocols. For instance, some common protocols for transferring emails are IMAP, POP3 and SMTP. Just as email is a layer on the internet, the World Wide Web is another layer which uses different protocols.

The World Wide Web uses three protocols: HTML (Hypertext markup language) - The language that we write our web pages in.

BLOG

A blog (a contraction of the words web log) is a discussion or informational site published on the World Wide Web and consisting of discrete entries ("posts") typically displayed in reverse chronological order (the most recent post appears first). Until 2009 blogs were usually the work of a single individual, occasionally of a small group, and often covered a single subject. More recently "multi-author blogs" (MABs) have developed, with posts written by large numbers of authors and professionally edited. MABs from newspapers, other media outlets, universities, think tanks, interest groups and similar institutions account for an increasing quantity of blog traffic. The rise of Twitter and other "micro blogging" systems helps integrate MABs and single-author blogs into societal new streams. Blog can also be used as a verb, meaning to maintain or add content to a blog.
The emergence and growth of blogs in the late 1990s coincided with the advent of web publishing tools that facilitated the posting of content by non-technical users.
(Previously, knowledge of such technologies as HTML and FTP had been required to publish content on the Web.) A majority is interactive; allowing visitors to leave comments and even message each other via GUI widgets on the blogs, and it is this interactivity that distinguishes them from other static websites.
In that sense, blogging can be seen as a form of social networking. Indeed, bloggers do not only produce content to post on their blogs, but also build social relations with their readers and other bloggers.There are high-readership blogs which do not allow comments, such as Daring Fireball.

WHAT IS HTML?

HyperText Markup Language (HTML) -is the main markup language for creating web pages and other information that can be displayed in a web browser. HTML is written in the form of HTML elements consisting of tags enclosed in angle brackets (like ), within the web page content. HTML tags most commonly come in pairs like (h1 to /h1), although some tags represent empty elements and so are unpaired, for example . The first tag in a pair is the start tag, and the second tag is the end tag (they are also called opening tags and closing tags). In between these tags web designers can add text, further tags, comments and other types of text-based content.

WHAT IS CSS?

Cascading Style Sheets (CSS) is a style sheet language used for describing the presentation semantics (the look and formatting) of a document written in a markup language. Its most common application is to style web pages written in HTML and XHTML, but the language can also be applied to any kind of XML document, including plain XML, SVG and XUL. CSS is designed primarily to enable the separation of document content (written in HTML or a similar markup language) from document presentation, including elements such as the layout, colors, and fonts.

This separation can improve content accessibility, provide more flexibility and control in the specification of presentation characteristics, enable multiple pages to share formatting, and reduce complexity and repetition in the structural content (such as by allowing for tableless web design).

CSS can also allow the same markup page to be presented in different styles for different rendering methods, such as on-screen, in print, by voice (when read out by a speech-based browser or screen reader) and on Braille-based, tactile devices. It can also be used to allow the web page to display differently depending on the screen size or device on which it is being viewed.

While the author of a document typically links that document to a CSS file, readers can use a different style sheet, perhaps one on their own computer, to override the one the author has specified
