A definition list divides a listing into two parts: the definition term - <DT>, and the indented definition itself - <DD>. The definition list is opened and closed with the container <DL> and </DL>. An empty line is placed between each term and its definition. If a definition term has more than one <DD> definition, then each definition is on a new line, but all are indented to the same level.

This is a definition list:

<DL>

<DT>HTML

<DD>HyperText Markup Language.

<DD>A computer language that tells the WWW how to format and display your text.

<DT>FreeNet

<DD>A cooperative, community-based information network.

</DL>
