Web development is a broad term for the work involved in developing a web site for the Internet (World Wide Web) or an intranet (a private network). Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, and social network services.
A more comprehensive list of tasks to which web development commonly refers, may include web design, web content development, client liaison, client-side/server-side scripting, web server and network security configuration, and e-commerce development.
Among web professionals, "web development" usually refers to the main non-design aspects of building web sites: writing markup and coding.
For larger organizations and businesses, web development teams can consist of hundreds of people (web developers). Smaller organizations may only require a single permanent or contracting webmaster, or secondary assignment to related job positions such as a graphic designer and/or information systems technician. Web development may be a collaborative effort between departments rather than the domain of a designated department.
Responsive web design is the most common One Web approach. The approach uses CSS media queries to modify the presentation of a website based on the size of the device display. The number of responsive sites is rapidly increasing.
The design and testing phase can be quite fussy, as it can be difficult to customize the user experience for every possible device or context. We’ve all seen responsive site layouts that look like a bunch of puzzle pieces that don’t quite fit together. Responsive web design works best in combination with a mobile-first approach, where the mobile use case is prioritized during development. Progressive enhancement is then used to address tablet and desktop use cases.
Of course, many companies are still wrestling with the basics of responsive, and they’re not ready to confront the more sophisticated flavors of adaptive. Increasingly, competition and mobile traffic, however, will drive more and more organizations to kick the tires on all three approaches, and pick the one that works best for their users.
