Web 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, and sounds) requires plug-ins such as Flash, QuickTime, Java run-time environment, etc. Plug-ins is 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.
A Web site is a collection of information about a particular topic or subject. Designing a web site is defined as the arrangement and creation of web pages that in turn make up a web site. A web page consists of information for which the web site is developed. A web site might be compared to a book, where each page of the book is a web page. There are many aspects (design concerns) in this process, and due to the rapid development of the Internet, new aspects may emerge. For non-commercial web sites, the goals may vary depending on the desired exposure and response.
