DL Item

dt and dd elements have to be wrapped in a parent dl element.

Accessibility

Why dl items must be wrapped in dl elements?

Users of assistive technologies such as screen readers need that web pages' elements are properly announced: therefore, <dt> and <dd> elements have to be wrapped in a parent <dl> element.

How this SeoChecker audit fails

If dl items aren't wrapped in <dl> elements, SeoChecker will notify it.

How can I fix orphaned definition list items

You need to use dl elements around the list, with dt elements that mark every term and dd elements related to every definition.

Have a look at the example below:

<dl>
  <dt>Trail shoe</dt>
    <dd>Extra grip for uneven, natural surfaces, such as forest trails.</dd>
  <dt>Road shoe</dt>
    <dd>Extra cushioning for hard surfaces, such as sidewalks and roads.</dd>
</dl>
