HTML supports unnumbered, numbered, and definition lists. You can nest lists too, but use this feature sparingly because too many nested items can get difficult to follow.

Unnumbered Lists

To make an unnumbered, bulleted list,

1. start with an opening list <UL> (for unnumbered list) tag
2. enter the <LI> (list item) tag followed by the individual item; no closing </LI> tag is needed
3. end the entire list with a closing list </UL> tag

Below is a sample three-item list:

    <UL>
    <LI> apples
    <LI> bananas
    <LI> grapefruit
    </UL>

The output is:

• apples
• bananas
• grapefruit

The <LI> items can contain multiple paragraphs. Indicate the paragraphs with the<P> paragraph tags.

Numbered Lists

A numbered list (also called an ordered list, from which the tag name derives) is identical to an unnumbered list, except it uses <OL> instead of <UL>. The items are tagged using the same <LI> tag. The following HTML code:

    <OL>
    <LI> oranges
    <LI> peaches
    <LI> grapes
    </OL>

produces this formatted output:

1. oranges
2. peaches
3. grapes

Definition Lists

A definition list (coded as <DL>) usually consists of alternating a definition term (coded as <DT>) and a definition definition (coded as <DD>). Web browsers generally format the definition on a new line.

The following is an example of a definition list:

    <DL>
    <DT> NCSA
    <DD> NCSA, the National Center for Supercomputing Applications,
         is located on the campus of the University of Illinois 
         at Urbana-Champaign. 
    <DT> Cornell Theory Center
    <DD> CTC is located on the campus of Cornell University in Ithaca,
         New York. 
    </DL>

The output looks like:

NCSA

NCSA, the National Center for Supercomputing Applications, is located on the campus of the University of Illinois at Urbana-Champaign.

Cornell Theory Center

CTC is located on the campus of Cornell University in Ithaca, New York.

The <DT> and <DD> entries can contain multiple paragraphs (indicated by <P> paragraph tags), lists, or other definition information.

Nested Lists

Lists can be nested. You can also have a number of paragraphs, each containing a nested list, in a single list item.

Here is a sample nested list:

    <UL>
    <LI> A few Southern states:
        <UL>
        <LI> Florida
        <LI> Alabama
        <LI> Georgia
        </UL>
    <LI> Two Midwestern states:
        <UL>
        <LI> Michigan
        <LI> Indiana
        </UL>
    </UL>

The nested list is displayed as

• A few Southern states:
  • Florida
  • Alabama
  • Georgia
• Two Midwestern states:
  • Michigan
  • Indiana
