The objective of this technique is to provide the definitions of words or phrases by
presenting them in a definition list. The list is marked up using the dl
element. Within the list, each term is put in a separate dt element, and
its definition goes in the dd element directly following it. The
title attribute can be used to provide additional information about the
definition list.
Using dl, dt, and dd ensures that relationships
between terms and their definitions are preserved if the presentation format changes and
that the list of terms and definitions is treated as a unit.
Definition lists are easiest to use when the definitions are put in alphabetical order. Definition lists are typically used in a glossary.

immediately following the word's dt element .
All checks above are true.
