Well-structured HTML documents come in three parts, consisting of
A HEAD that identifies the document as HTML and establishes its title
A BODY that contains the content for a Web page. This part holds all displayed text on a page, as well as all links to graphics, multimedia information, locations inside the same HTML file, or other Web documents.
A FOOTER that labels the page by identifying its author, date of creation, and version number (if applicable).
HTML does have versions: 2.0, 3.0, 3.2 and so forth as times travels!
