<dl> elements must only directly contain properly-ordered <dt> and <dd> groups, <script>, or <template> elements
Definition lists (
dl) must contain only properly-ordered
Why it Matters
Screen readers have a specific way of announcing definition lists. When such lists are not properly marked up, this creates the opportunity for confusing or inaccurate screen reader output.
A definition list is used to provide the definitions of words or phrases. The Definition 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.
How to Fix the Problem
Check that your definition list has only
dd elements. Furthermore, make sure these are properly ordered,
dt should precede
Definition list items require
dl elements around the list,
dt elements for each term, and
dd elements for each definition. Each set of
dt elements must be followed by one or more
dd elements. Ensure that your definition lists follow these specifications and mimic the example below.
<dl> <dt>Coffee</dt> <dd>Black hot drink</dd> <dt>Milk</dt> <dd>White cold drink</dd> </dl>
The Algorithm (in simple terms)
Ensures that all
dl elements are structured correctly.
