The items within the list are introduced by the two elements
<DT>-- The 'Term'
<DD>-- The 'Definition'
DL can take a single attribute, COMPACT, to signify that the list is small (or large) and should be rendered in a physically compact way. Note that many browsers do not perform any special rendering on encountering the COMPACT attribute.
<dl> <dt> Things to Avoid: <dd> You should NOT use elements that define paragraph formatting within the PRE element. This means you should not use <code> <P>, <ADDRESS>, <Hn> </code>and so on. You should avoid the use of tab characters -- use single blank characters to space text apart. <dt> Things That are OK: <dd>You <em> can </em> use Anchor. A typed carriage return will cause a new line in the presented text. People you should never let format lists include: <ul> <li> Bozo the Clown <li> Uncle Fester <li> Knights who go nii </ul> Which would be donwright silly in the first place. </dl>
Note that the DD element can contain a wide range of elements, including P, BLOCKQUOTE, FORM and even other lists (even other DL's), so DL can form quite a powerful organizing structure of complex textual material. Moreover you can have more than DT associated with a single DD and vice versa (or you can have a DT without a DD, and vice versa. Careful thought should be given to the meaning of such usage, but there are occasions when such elaborate markup is appropriate and effective.
