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.

In practice, many web developers will have basic interdisciplinary skills / roles, including:

  1. Graphic design/ web design
  2. Information architecture and copy-writing/copy-editing with web usability, accessibility and search engine optimization in mind
  3. Mobile responsiveness

The above list is a simple website development hierarchy and can be extended to include all client side and server side aspects. It is still important to remember that web development is generally split up into client side coding, covering aspects such as the layout and design, and server-side coding, which covers the website's functionality and back-end systems.

Web development takes into account many security considerations, such as data entry error checking through forms, filtering output, and encryption. Malicious practices such as SQL injection can be executed by users with ill intent yet with only primitive knowledge of web development as a whole. Scripts can be used to exploit websites by granting unauthorised access to malicious users that try to collect information such as email addresses, passwords and protected content like credit card numbers. Some of this is dependent on the server environment on which the scripting language, such as ASPJSPPerlPHPPythonPerl or Ruby is running, and therefore is not necessarily down to the web developer themselves to maintain. However, stringent testing of web applications before public release is encouraged to prevent such exploits from occurring. If some contact form is provided in a website it should include a captcha field in it which prevents computer programs from automatically filling forms and also mail spamming. Keeping a web server safe from intrusion is often called Server Port Hardening. Many technologies come into play to keep information on the internet safe when it is transmitted from one location to another. For instance TLS certificates (or "SSL certificates") are issued by certificate authorities to help prevent internet fraud. Many developers often employ different forms of encryption when transmitting and storing sensitive information. A basic understanding of information technology security concerns is often part of a web developer's knowledge. Because new security holes are found in web applications even after testing and launch, security patch updates are frequent for widely used applications. It is often the job of web developers to keep applications up to date as security patches are released and new security concerns are discovered.

The five most popular web browsers have support for web developer tools that allow web designers and developers to look at the make-up of their pages. These are all tools that are built into the browser and do not require additional modules or configuration.
