(X)HTML provides a special tag for creating definition lists. This type of list is particularly suited to glossaries, but works well with any list that pairs a word or phrase with a longer description. Imagine, for example, a list of Classical Greek verb tenses, each followed by an explanation of proper usage.
To create definition lists:
Figure 15.19. Each entry word is labeled with the dt tag, while the definition itself is labeled with a dd tag.
Figure 15.20. You may want to add formatting to your definition term to help it stand out.
Figure 15.21. By default, the defined word (the dt) is aligned to the left and the definition (dd) is indented.
