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

For weaker emphasis, use the EM element.
