The DL element declares that the embedded information should be presented in the form of a Glossary list. It is a sequence of terms and their descriptions. Glossary (or dictionary) lists are composed of two type of elements, DT and DD.
The DT element lists the name of an item in a Glossary List.
The DD element lists the definition of the preceding item (DT) in a Glossary List.
The DIR element declares that the embedded information should be presented in the form of a Directory. It is a sequence of short items. Many browsers will present the directory as a series of columns.
The MENU element declares that the embedded information should be presented in the form of a Menu. It is a sequence of short items. It is similar to the Unordered List (UL) with the compact attribute. Many browsers will present the Menu identically with the UL lists.
The OL element declares that the embedded information should be presented in the form of a Ordered List. It is a sequence of items which are numerically ordered. The browsers will order the list by numbering its items. Some browsers will use ascending letters.
The UL element declares that the embedded information should be presented in the form of an Unordered List. It is a sequence of items which are indicated by a bullet or other special symbol. Netscape allows one to define the symbol.
The LI element is the item within a list. Except for Glossary Lists, LI is used with all lists.
