Ordered List:
You can create numbered, or ordered lists, by using the <OL> (ordered list) tag. The format is:

<OL>
<LI>item one
<LI>item two
<LI>item three
</OL>

The ordered list will look like this:

1. item one
2. item two
3. item three

Unordered List:
To create bulleted, or unordered lists, use the <UL> (unordered list) tag. The format is:

<UL>
<LI>item one
<LI>item two
<LI>item three
</UL>

The unordered list will look like this:

• item one
• item two
• item three

Definition List:
The definition list is somewhat different and can be used to automatically indent certain parts of your text by using the <DL> (definition list) tag. The easiest way to explain a definition list is to show one:

<DL>
<DT> Oranges
<DD> A reddish-yellow tropical fruit about the size of an apple. A member of the citrus fruit family. In the United States, oranges are grown primarily in the states of Florida and California.
<DT> Apples
<DD> Technically a pome, apples are an orange-sized fruit, usually in varying shades and mixtures of red, yellow, and green. In the United States, apples are grown primarily in the northern states, near bodies of water.
</DL>
