<dl>
<dt>Domino mask</dt>
<dd>

obscurity.</p>
<p>The name comes from the Latin <i lang="la">dominus</i>, meaning “lord”
or “master.”</p>
</dd>
<dt>Cowl</dt>
<dd>A head covering combining a hood and a collar or mantle.</dd>
<dd>A streamlined covering around an aircraft engine or personal jetpack.</dd>
</dl>
Most browsers will display dd elements slightly indented from their corresponding dt. When a dd contains
other structural markup (such as paragraphs), the default margins of that nested element will apply. As you
can see in Figure 4-11, the paragraphs in the first term’s description have default margins above and

modify all of this, of course, with CSS.
