XML in a Nutshell, 3rd Edition

List Elements

An element whose display property is set to list-item is also formatted as a block-level element. However, a bullet is inserted at the beginning of the block. The list-style-type, list-style-image, and list-style-position properties control which character or image is used for a bullet and exactly how the list is indented. For example, this rule would format the steps as a numbered list rather than rendering them as a single paragraph:

step {
  display: list-item;
  list-style-type: decimal;
  list-style-position: inside
}
