TitleIn HTML, the tag TITLE defines the text to be displayed on a page's title bar. Unlike the heading <HEAD>, the title is displayed within the text of a document.
Every HTML document must contain a TITLE element. In fact, the minimal HTML 3.0 document consists of the TITLE element alone.
The title identifies the contents of the document in a global context, and may appear both in the history list and as a label for the window displaying the document. Titles should be descriptive as possible and not too long, as they are used as a data element for search engines looking for information on the Web. While the length of titles is unlimited, long titles may be truncated in some applications. To minimize this possibility, titles should be fewer than 64 characters.
