    <sup>

    Summary

    The HTML Superscript Element (<sup>) defines a span of text that should be displayed, for typographic reasons, higher, and often smaller, than the main span of text.

    Usage note:

    • This element should be used for typographical reasons only, i.e. changing the position of the text changing its meaning like in mathematical (like f4, though the use of a MathML formula should be considered) or in French abbreviations (like Mlle, Mme or Cie).
    • This element must not be used for styling purpose like the styling of the product name Latex. In that case CSS style should be used: the vertical-align property with the super value will achieve the same effect.
