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

Serious

What is the problem?

The dlitem accessibility rule ensures that <dt> (definition term) and <dd> (definition description) elements are used correctly within a <dl> (definition list) element.

Why is this important?

Screen readers rely on the correct structure of definition lists to understand the relationship between terms and their descriptions. Incorrectly structured lists can confuse screen readers, making it difficult for users to access and understand the information.

How to solve this issue

To fix this issue, ensure that <dt> and <dd> elements are always paired and enclosed within a <dl> element. The <dt> element should come before the corresponding <dd> element. This correct structure helps screen readers accurately convey the information to users.
