EM - Emphasis

Syntax	<EM>...</EM>
Attributes	common attributes
Contents	Inline elements
Contained in	Inline elements, block-level elements

The EM element gives emphasis to its contents. Visual browsers typically render EM as italic text, but authors can suggest a rendering using style sheets. Since EM is a structural element, it carries meaning, making it preferable to font style elements such as I when emphasis is the intended meaning.

For strong emphasis, use the STRONG element.
