<DT> </DT>

The DT tag is used inside of the DL command, and it marks up a term whose definition is in the next DD. The DT tag can contain only text-level markup. The format should be a DL followed by a DT with the word to be defined, and then a DD with the definition.

Example:

<DL>
<DT>HTML</DT>
<DD>Hyper Text Markup Language</DD>
</DL>
