Web design represents the planning and creation of websites. It includes all the information, such user interface, site structure, navigation, layout, colors, fonts, and imagery. All of these are combined with the principles of design to create a customized website that meets the requirements  of the owner and web designer.

Many years ago the websites were used only by educational institutions and government agencies in order to make information available to each other via text-only websites. Nowadays the web is widely opened to the public and there are so many types of websites that is difficult to distinguish them.
Before trying to categorize the web site, let’s see how can we define a website? A Website is a set of related web pages served from a single web domain. A website is hosted on at least one web server, accessible via a network such as the Internet. All publicly accessible websites collectively constitute the World Wide Web.
