logical markup

The two types of HTML character tags are either logical markup or physical markup. Logical tags are intended to indicate the meaning of the character tag. For example, a logical tag for emphasizing text is to flag it as <strong>….</strong>.

The physical tag which indicates emphasis is <bold>…</bold>.

Logical tags exist to create consistency among documents, and to help separate elements. While they change a document's physical appearance, logical tags are more equipped to track the types of information therein Physical tags act directly on text--changing its appearance to bold, italics, and so on.
