HTML Document

The brief answer is :- It is a web page.

Web pages are nothing more than another type of document. In fact, they're really nothing more than a page of text instructions that your web browser reads.

HTML is short for Hyper Text Markup Language.

It is the programming language of web pages (technically however, HTML is not a programming language).

HTML gives your web browser instructions on how to display the HTML document (web page) you're accessing. If you would like to look further at this HTML stuff, open Internet Explorer or Firefox and head to your favourite site.

From the View menu, select Page Source or View Source (depending on your browser and version).
