Web design encompasses many different skills and disciplines in the production and maintenance of Web sites. The different areas of web design include web graphic design; interface design; authoring, including standardized code and proprietary software; user experience design; and search engine optimization.
Often many individuals will work in teams covering different aspects of the design process, although some designers will cover them all. A web designer is concerned with how a site looks and how the customers interact with it. Good web designers know how to put together the principles of design to create a site that looks great. They also understand about usability and how to create a site that customers want to navigate around in because it’s so easy to do.
The term web design is normally used to describe the design process relating to the front-end (client side) design of a Website including writing mark up. Web design partially overlaps web engineering in the broader scope of web development. Web designers are expected to have an awareness of usability and if their role involves creating markup then they are also expected to be up to date with web accessibility guidelines.
