<sub>

The <sub> element indicates that text should appear with subscript highlighting, or placed lower in relationship to the surrounding text. Subscripted text is often a smaller font than the surrounding text. Formatting might vary depending on your output process. This element is part of the highlighting domain. Use this element only when a more semantically appropriate element is not available.

Note (non-normative):
Style sheets can be used to format the <sub> element differently, just like any other element can be restyled. Thus, it is not the case that content in <sub> elements will necessarily be rendered as subscript.
