Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as dd.
The <dl> element, used to create a definition lists that matches some terms with their definitions, has nesting issues related to <div> elements used with it.
The <dl> element is used in HTML to represent a description list. The element encloses a list of groups of terms (specified using the <dt> element) and descriptions (provided by <dd> elements). Common uses for this element are to implement a glossary or to display metadata (a list of key-value pairs).
For example, the following is a description list with a single term and its definition:
<dl> <dt>Rocket Validator</dt> <dd> The fastest site-wide HTML and Accessibility checker. </dd> </dl>
Description lists also allow to specify different terms for the same definition, as in this example:
<dl> <dt>Rocket Validator</dt> <dt>Rocket</dt> <dt>RV</dt> <dd> The fastest site-wide HTML and Accessibility checker. </dd> </dl>
Or, we can have a single term with multiple definitions:
<dl> <dt>Rocket Validator</dt> <dd> The fastest site-wide HTML and Accessibility checker. </dd> <dd> The web site you're browsing right now. </dd> </dl>
In all of these cases, a <dt> term always requires one (or more) <dd> definition elements, so the following is invalid because it’s incomplete, it has an undefined term:
<dl> <dt>The Meaning of Life</dt> </dl>
