7.5. Definition Lists
HTML and XHTML also support a list style entirely different from the
ordered and unordered lists we've discussed so far: definition lists. Like
the entries you find in a dictionary or encyclopedia, complete with text,
pictures, and other multimedia elements, the definition list is the ideal
way to present a glossary, list of terms, or other name/value list.
7.5.1. The <dl> Tag
The definition list is enclosed by the <dl> and </dl> tags. Within the tags,
each item in a definition list is composed of two parts: a term, followed
by its definition or explanation. Instead of <li> , each item name in a <dl>
list is marked with the <dt> tag, followed by the item's definition or ex-
planation marked by the <dd> tag.
