HTML <em> Tag

<p>Wow, I <em>really</em> like this song!</p>

The above example demonstrates usage of the <em> element.

The <em> element is used for marking up text with stress emphasis.

The <em> element should not be used for placing importance on its contents — it is specifically designed to represent stress emphasis without conveying extra importance.

In particular, the <em> element should not be confused with the <strong>, <i>, or <b> elements, each of which have their own specific semantics.
