Web page design is a process of conceptualization, planning, modeling, and execution of electronic media content delivery via Internet in the form of technologies (such as markup languages) suitable for interpretation and display by a web browser or other web-based graphical user interfaces (GUIs).

The intent of web design is to create a web site (a collection of electronic files residing on one or more web servers) that presents content (including interactive features or interfaces) to the end user in the form of web pages once requested. Such elements as text, forms, and bit-mapped images (GIFs, JPEGs, PNGs) can be placed on the page using HTML, XHTML, or XML tags. Displaying more complex media (vector graphics, animations, videos, sounds) usually requires plug-ins such as Flash, QuickTime, Java run-time environment, etc. Plug-ins are also embedded into web pages by using HTML or XHTML tags.

Improvements in the various browsers’ compliance with W3C standards prompted a widespread acceptance of XHTML and XML in conjunction with Cascading Style Sheets (CSS) to position and manipulate web page elements. The latest standards and proposals aim at leading to the various browsers’ ability to deliver a wide variety of media and accessibility options to the client possibly without employing plug-ins.

Web development is a broad term for any activity related to developing a web site for the World Wide Web or an intranet. This can include e-commerce business development, web design, web content development, client-side/server-side scripting, and web server configuration. However, among web professionals, “web development” usually refers only to the non-design aspects of building web sites, e.g. writing markup and coding. Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, or social network services.
