Ordered List <OL></OL> This element is used to define an ordered or numbered list of items. The numbering style comes in many forms, including letters, Roman numerals, and regualr numerals. The individual items within the list are specified by <LI> elements included with the <OL> element. <OL START> This attribute is used to indicate the value to start numbering the individual list items from. While the ordering type of list elements may be Roman numerals like XXXI or letters, the value of START is always represented as a number. To start numbering elements from the letter "C ", use <OL TYPE="A" START="3">. <OL TYPE> This attribute indicates the numbering type: "a" indicates lowercase letters, "A" indicates uppercase letters, "i" indicates lowercase Roman numerals, "I" indicates uppercase Roman numerals, and "1" indicates numbers. Type set in the <OL> element is used for the entire list unless the TYPE attribute is used within an enclosed <LI> element. Unordered List <UL></UL> This element is used to indicate an unordered list, namely, a collection of items that do not have a numerical ordering. The individual items in the list are defined by the <LI> element, which is the only allowed element within <UL>. <UL TYPE> The TYPE attribute is used to set bullet style for the list. The values defined under HTML 3.2 and the transitional version of HTML 4 are circle, disc, and square. <LI> This element is used to indicate a list item as contained in an ordered list (<OL>), and unordered list (<UL>). <LI TYPE> This attribute indicates the bullet type used in unordered list or the numbering type used in ordered lists. For ordered list, a value of "a" indicates lowercase letters, "A" indicates uppercase letters, "i" indicates lowercase Roman numerals.

A common use for this element is to implement a glossary. <DT> This element indentifies a definition list term in a definition list term-definition pair. <DD> This element indicates the definition of a term within a list of defined terms (<DT>) enclosed by a definition list (<DL>).
