Markup for three types of lists are provided in XHTML:

1. Unordered (ul): no obvious ordering to the items in the list
2. Ordered (ol): clear ordering of the items in the list
3. Definition (dl): a list of terms followed by an associated description

It is not always obvious which one to choose!

• Start and end tags are always needed
• dl, ul and ol are standard block-level elements
• The <li> element is used to specify list items in ul and ol lists
• The li element is neither a block level or inline element because:
  • It can only appear as a child of the ul or ol elements
  • It behaves like a div
  • Browsers normally render it with the list bullet or number outside the content box
  • A browser normally renders a bullet in front of each unordered list item
  • A browser normally renders a number in front of each ordered list item
• By default, the browser chooses the type of bullet or form of number
