Web Design in a Nutshell, 3rd Edition

Unordered Lists

Unordered lists are used for collections of related items that appear in no particular order. Most lists fall into this category. Just about any list of examples, components, thoughts, or options should be marked up as an unordered list. Most notably, unordered lists are the element of choice for navigational options. Unordered lists for navigation are discussed later in this section.

In (X)HTML, unordered lists are denoted with the ul element. The content of a ul is limited to one or more list items (li). List items may contain either block-level or inline elements, or both. Unordered lists and their list items are block elements, so each will display starting on a new line.
