<sup>
The <sup> element indicates that text should appear with
superscript highlighting, or vertically raised in relationship to the surrounding text.
Superscripts are usually a smaller font than the surrounding text. This element is part of the highlighting domain. Use this element only when a more semantically appropriate element is not available.
Note: Style sheets can be used to format the
<sup> element differently, just like any other element
can be restyled. Thus, it is not the case that content in
<sup> elements will necessarily be rendered as
superscript.Content models
