Web design encompasses a variety of disciplines and skills in the creation and management of web sites. The various disciplines of web design cover web graphic design; web user interface design; website authoring, with emphasis on website functionality and aesthetic elements; website usability testing; and search engine marketing and optimization. Aesthetics are an important component of web design. User interface (ui) design draws visitors through use of icons, text, and layouts. Website authoring is the process of putting information on a website, usually consisting of images, code or videos.
Web designers work with all these disciplines to produce a product that is visually attractive as well as easy to operate and navigate. Although web designers can choose to specialize in any one of these disciplines, the most common is visual communication, which includes art direction, typography, illustration, and other design components such as color, contrast, texture, and unity. These components allow users to “sense” the information on the website, and “compose” it in a way that they deem appropriate.
Another important area of web design is usability, which is the ability of users to interact effectively and accurately with the information on a site. Web designer must be concerned with usability at both the source and target audience. Making sure that the content of the site is easy to read and uses appropriate typography, graphics, and color in a layout that is easy to navigate is the goal of the designer. In order to ensure that usability is at the heart of the web design process, usability testing is important to make sure that the site is not only readable but also easy to use by the target audience.
