Create a definition list
When you want to present a list of terms and definitions, you can add a definition list to your page. Terms are usually displayed flush left, with indented definitions. The exact formatting of the list depends on the web browser that site visitors use.
You can set many other properties for a list, such as margins and text properties, by applying a style to the list or a particular list item. For more information, see Create a style.
In Design view or Code view, in your web page, place your cursor where you want to create a list of definitions, and then do one of the following.
On either the Common or Formatting toolbar, click the Style box, and then click Defined Term.
On the Format menu, click Bullets and Numbering. In the Bullets and Numbering dialog box, click the Other tab. Under List Style, click Definition List, and then click OK.
Type the first term in the list, and then press ENTER. The next line is automatically formatted with the Definition style.
Type the term definition.
Press ENTER to continue to the next term. The next line is automatically formatted with the Defined Term style.
Repeat steps 4 through 6 for each term and definition.
To end the list, press ENTER twice.
