Every HTML document must contain a <TITLE> element.
The title should identify the contents of the document in a global context. A short title, such as "Introduction" may be meaningless out of context. A title such as "Introduction to HTML Elements" is more appropriate.
A user agent may display the title of a document in a history list or as a label for the window displaying the document. This differs from headings, which are typically displayed within the body text flow.
