Template:Lower/doc

Use to lower some text or other element a specified number of units – the proportional "em" units are recommended – otherwise by a default 0.6em:
 * to lower by N em units (e.g. This is the text to lower. )
 * to lower by the default amount.

Can be useful e.g. to position erence links (footnote links) appearing in tables without any preceding text (cf. Infobox ethnic group).
