This element encloses text which is the title or name of a source document. Typically, this is used in citations of books or documents.
Use this for works that are cited.
This is usually rendered as italics text in the browser.
Note that different citation styles that vary from
publication to publication use different kinds
of physical emphasis for titles of books, poems,
articles, or other works.
You could use EM for emphasis or I for when you must have italics.
