There are a few methods with HTML to present a list of items. The two most commonly used are the Ordered List <OL> </OL> and the Unordered List <UL> </UL>. Both types of lists will indent their items and present them in a single column format. The difference is that ordered lists automatically number the items and unordered lists use bullets. You may have noticed that each time I show attributes for a tag I use an unordered list. Each item within a Ordered or Unordered list is designated by a List Item <LI> tag. The <LI> tag does not have a closing tag because when a browser reaches another <LI> or closing list tag (</OL> or </UL>), it knows the previous item is complete.
Lists can be nested, which means you can have lists within lists. They can even be mixed so you can include an ordered list within an unordered list or vice versa. Lists have a few optional attributes, depending on the type. The <LI> tag can have the same attributes the parent list has, this allows you to change numbering/bullets types in the middle of a list.Ordered Lists: <OL> </OL>
