Web development generally refers to the tasks associated with the development of websites intended to be hosted via an intranet or the Internet.
The web development process includes, but is not limited to, website design, web content development, client-side or server-side scripting, and network security configuration.
Web development also involves the coding or programming that makes a website work, as required by the owner.
It mainly deals with the non-design side of website building, which includes coding and writing markup.
