<underline>

Underline

Used to mark text that should appear with a horizontal line beneath it.

Remarks

This is normally a print consideration — not a matter for XML tagging — as underlining is frequently prohibited in online works, since it is a common “this is a link” signal.

Related Elements

The <underline> element is used for ordinary underlining. For underlining that involves problems with element overlap, use the milestone elements <underline-start> and <underline-end> to mark the start and end of the sequence to be underlined.
