As web page authors though, you need to know the full hierarchy if only to know where to deposit your files. The server root and user roots are assumed to contain unrelated contents. Occasionally, you may be asked to author some pages that are logically part of the subjects covered by the main server. However, you can ask for a link to be made between the server's home page to your home page. Otherwise, you are free to treat your own pages as separate from the main pages.
Web pages are hierarchical collection of pages.
Each page contains a link or multiple links to other pages. As a security precaution, the web server will ignore most directives. At a minimum a web page may contain text, formatted text, inline images and links. Links may point to other web pages, or multimedia content some of which are listed in the table below. The content types from Portable Document Format to GNU Lempel-Ziv Encoding in the table below cannot be placed as part of a HTML document but may appear as links.
