HTML Ordered Lists overview 

An ordered list is a list of items that must be followed in a specific order, such as in a recipe or directions to someone's home. Ordered lists are also called numbered lists

Two elements are required to create an ordered list. The first is the <ol>. . . </ol> (ordered list) element, and the second is the <li> . . . </li> (list item)
