The design process of a website which includes writing markup for a client and encompasses many skills and disciplines in the production and maintenance of a website is referred to as web design. The various skills and disciplines contained in web design include web graphic design, interface design, user experience design, search engine optimization and authoring which include standardized code and proprietary software. An individual who wishes to do web design should be aware of the web usability which is the ease of use of a website. It is also important for an individual who is creating mark up during web design to be updated with all the available web accessibility guidelines. A web designer can work all alone in the different web design aspect although some works together as a team covering the different aspects. Web design and web engineering are somehow related although web engineering is broader and focuses mostly on methodologies, techniques, and tools that form the foundation for web application development which support their design, development, evolution and evaluation.
Web design has many different processes during production and each process uses a different tool and technology which are updated on regular basis by newer standards and software. Creating of web formatted imagery and design prototypes uses two major graphics editor referred to as vector and raster graphics. Polygons are used in vector graphics to represent images in graphics which are later saved in any vector graphics format such as WMF and PDF. Raster graphics use dot matrix data structure representing a grid of pixels or points of color viewable on a monitor which can be saved in any bitmap or raster format such as JPEG and GIF. Websites can be created by various technologies such as the W3C standards like HTML and CSS. These can be done by online proprietary tools provided by web hosting companies which are intended for users to build their private site or it can be done by an offline software running on a computer creating pages and then these pages can be published on any host. Web design can also make use of markup validators for checking validity and other testing tools for usability and accessibility to ensure all the guidelines for web accessibility have been met.
During web design process, the web designer and the web developer works hand in hand in creating a website. The web designer focuses on the visual aspect such as the layout coloring and typography of the web page. Knowledge in the markup language for a web designer is key and it is a system involved in annotating a document in a way that it is syntactically distinguishable from a text such as the HTML and CSS.
