Citations & Definitions

< cite>

When you are referencing a piece of work such as a book, film or research paper, the < cite> element can be used to indicate where the citation is from.
In HTML5, < cite> should not really be used for a person's name — but it was allowed in HTML 4, so most people are likely to continue to use it.
Browsers will render the content of a < cite> element in italics.

Example

HTML	Result
< p> < cite>A Brief History of Time< /cite> by Stephen Hawking has sold over ten million copies worldwide. < /p>	A Brief History of Time by Stephen Hawking has sold over ten million copies worldwide.

< dfn>

The first time you explain some new terminology (perhaps an academic concept or some jargon) in a document, it is known as the defining instance of it.
The < dfn> element is used to indicate the defining instance of a new term.
Some browsers show the content of the < dfn> element in italics. Safari and Chrome do not change its appearance.

Example

HTML	Result
< p>A < dfn>black hole< /dfn> is a region of space from which nothing, not even light, can escape.< /p>	A black hole is a region of space from which nothing, not even light, can escape.
