HTML
<dt>
element
specifies a term in a description or definition list, and as such must be used inside a
<dl>
元素。
It is usually followed by a
<dd>
element; however, multiple
<dt>
elements in a row indicate several terms that are all defined by the immediate next
<dd>
元素。
The subsequent
<dd>
(
Description Details
) element provides the definition or other related text associated with the term specified using
<dt>
.
