Use HTML and XHTML according to their respective specifications. <dd>
elements should be inside a <dl>
element. They should follow a <dd>
or <dt>
element.
Engine scans for <dd>
elements which next sibling is not a <dd>
or <dt>
element<br>
or which are not the children of a <dl>
element
Not using HTML according to the specification leads to confusion for user agents and assistive technologies that rely on correct semantic information to present a coherent representation of the page.
