A standard HTML set of tags allows you to create lists on a web page. There are three standard types of lists, ordered, unordered, and definition. Ordered and unordered lists pretty much work the same way, while definition lists have a very different set of tags. An ordered list will automatically number its items, an unordered list will be a bullet list. An unordered list can be bulleted, hollow bullets, or squares.
Definition lists work differently.
The first is definition term, the second definition description. The definition term is for what you want to define and the definition description will automatically indent content under the definition term, a bit like a subheading. View source to see the code for the following.
