<dl> elements must only directly contain properly-ordered <dt> and <dd> groups, <script>, <template> or elements

Definition lists (dl) may only contain dt and dd groups, div, script, or template elements that are properly organized.

Screen readers have a particular method for reading definition lists. When such lists are not correctly marked up, screen reader output may be erroneous or confusing.

A list of definitions is used to explain the meaning of words or phrases. Using the dl element, the definition list is formatted. Within the list, each term is enclosed in its own dt element, and its definition is enclosed in the dd element that immediately follows.

What this Accessibility Rule Checks

Ensures that each dl element is correctly constructed.
