Use HTML and XHTML according to their respective specifications. <dt>
elements should be inside a <dl>
element. They should precede a <dd>
or <dt>
element
Engine scans for dt elements whose previous sibling is not a <dd>
or <dt>
element and which are not the child 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.
