The DD element provides the definition of a term in a definition list. The closing tag for DD is optional, but its use prevents common browser bugs with style sheets.
DD may contain block-level elements such as P, H2, TABLE, and DL. This allows definition lists to be nested, as in the following example:
<DL>

<DT><A NAME="spanning-tree">Spanning tree</A></DT>
<DD>
<P>
A spanning tree of a graph is a <A HREF="#tree">tree</A>
that contains all the vertices of the graph. There are two
main types of spanning trees:
</P>

<DL>
<DT>BFS spanning tree</DT>
<DD>
A spanning tree formed by a breadth-first search on the graph.
</DD>
<DT>DFS spanning tree</DT>
<DD>
A spanning tree formed by a depth-first search on the graph.
</DD>
</DL>
</DD>

<DT><A NAME=tree>Tree</A></DT>
<DD>
<P>
A tree is a connected, undirected graph without cycles.
</P>
</DD>

</DL>
A DD element should generally be preceded by a DT element that gives the term defined by the DD. A single definition term may have multiple definitions associated with it, and a single definition may have multiple terms.
