How to fix orphaned definition list items

Wrap all definition list items in parent dl elements to ensure the list follows the proper hierarchy.

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. For example:

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