<dt> and <dd> elements must be contained by a <dl>

Definition list items (dt and/or dd) must be wrapped in parent dl elements to be valid. This enables screen reader users to understand the proper hierarchy of information in the list.

A definition list item must be wrapped in parent dl elements, otherwise it will be invalid.

A definition list must follow a specific hierarchy. A list is defined using the dl element. What follows are alternating sets of dt and dd elements, starting with the dt element. dt elements define a term while dd elements denote a term's description. Each set of dt elements must have a corresponding set of dd elements. Only dt and dd elements are allowed in definition list. If this hierarchy is not followed, the list will be invalid.
