The work involved in creating a website for the Internet (World Wide Web) or an intranet (a private network) is known as web development. Web development can include everything from creating a single static page of plain text to creating large web apps, electronic companies, and social network services. Web engineering, Web design, Web content creation, client liaison, client-side/server-side scripting, Web server and network security settings, and e-commerce development are some of the more comprehensive jobs to which Web development typically refers.

“Web development” is commonly used among Web professionals to refer to the main non-design parts of constructing Web sites: writing markup and coding. Content management systems (CMS) may be used in web development to make content modifications easier and more accessible to those with basic technical abilities.

Web development teams for larger organizations and corporations might consist of hundreds of people (Web developers) and use standard approaches such as Agile methodology while constructing Web sites. Smaller firms may just require a single permanent or contracting developer, as well as secondary assignments to adjacent employment positions such as graphic designer or information systems technician. Web development may be a collaborative endeavor among departments rather than the responsibility of a single department. Web developer specializations are divided into three categories: front-end developer, back-end developer, and full-stack developer. Front-end developers are in charge of the behavior and graphics that appear in the user’s browser, whereas back-end developers work with the servers.
