A web site is a collection of information about a particular topic or subject. 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. 

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).
