Definition Lists

A definition list is as ancient of an HTML construct as you can find. However, these are sorely underused, which is a shame because they provide a great way to define terms and concepts.

Definition lists consist of three elements: the definition list element, <dl>. . . </dl>; the definition term element, <dt>. . .</dt>, and the definition description element, <dd>. . .</dd>.

You can have multiple instances of terms within a definition list (see Example 2-8).

Example 2-8. Multiple definitions within a list
     <dt>Furkid (n)</dt>
     <dd>A pet treated as though it were one's child.</dd>

     <dt>Nearshoring (v)</dt>
     <dd>Restructuring a company's workforce by moving jobs to a nearby
         foreign country.</dd>

     <dt>Neurodiversity (n)</dt>
     <dd>The variety of non-debilitating neurological behaviors and
         abilities exhibited by the human race.</dd>

The browser displays the term, and the definition itself is indented (see Figure 2-8).

You'll be able to use CSS to add styles such as fonts and color if you want to add a little flair to your list.
