What is a web page?
How does a web page work?
A web page differs from a website. A website is made up of multiple web pages, at the bare minimum an index page (more often called a home page). Each web page is stored as a single file on a web server, though it may integrate content from multiple sources.
Besides HTML, web pages can include code written in PHP, ASP, and Perl. Web page design, formatting, and style is usually governed by a separate CSS file.
