WEB DESIGN..

Web design is the skill of creating presentations of content (usually hypertext or hypermedia) that is delivered to an end-user through theWorld Wide Web, by way of a Web browser or other Web-enabled software like Internet television clients, microblogging clients and RSS readers.

The process of designing Web pages, Web sites, Web applications or multimedia for the Web may utilize multiple disciplines, such asanimation, authoring, communication design, corporate identity, graphic design, human-computer interaction, information architecture,interaction design, marketing, photography, search engine optimization and typography.

• Markup languages (such as HTML, XHTML and XML)
• Style sheet languages (such as CSS and XSL)
• Client-side scripting
• Server-side scripting (such as PHP and ASP)
• Database technologies (such as MySQL and PostgreSQL)
• Multimedia technologies (such as Flash and Silverlight)

Web pages and Web sites can be static pages, or can be programmed to be dynamic pages that automatically adapt content or visual appearance depending on a variety of factors, such as input from the end-user, input from the Webmaster or changes in the computing environment (such as the site's associated database having been modified).

With growing specialization within communication design and information technology fields, there is a strong tendency to draw a clear line between web design specifically for web pages and web development for the overall logistics of all web-based services.

COLOUR THEORY..

In the visual arts, color theory is a body of practical guidance to color mixing and the visual impacts of specific color combinations. Although color theory principles first appear in the writings of Leone Battista Alberti (c.1435) and the notebooks of Leonardo da Vinci (c.1490), a tradition of "colory theory" begins in the 18th century, initially within a partisan controversy around Isaac Newton's theory of color (Opticks, 1704) and the nature of so-called primary colors. From there it developed as an independent artistic tradition with only superficial reference to colorimetry and vision science.
