Web design is a process of conceptualization, planning, modeling, and execution of electronic media delivery via Internet in the form of Markup language suitable for interpretation by Web browser and display as Graphical user interface (GUI).
The intent of web design is to create a web site — a collection of electronic files that reside on a web server/servers and present content and interactive features/interfaces to the end user in form of Web pages once requested. Such elements as text, bit-mapped images (GIFs, JPEGs, PNGs), forms can be placed on the page using HTML/XHTML/XML tags. Displaying more complex media (vector graphics, animations, videos, sounds) requires plug-ins such as Flash, QuickTime, Java run-time environment, etc. Plug-ins are also embedded into web page by using HTML/XHTML tags.
Improvements in browsers’ compliance with W3C standards prompted a widespread acceptance and usage of XHTML/XML in conjunction with Cascading Style Sheets (CSS) to position and manipulate web page elements and objects. Latest standards and proposals aim at leading to browsers’ ability to deliver a wide variety of media and accessibility options to the client possibly without employing plug-ins.
Typically web pages are classified as static or dynamic.
Static pages don’t change content and layout with every request unless a human (web master/programmer) manually updates the page.
With growing specialization in the information technology field there is a strong tendency to draw a clear line between web design and web development.
