Original Source

The <msup> MathML element is used to attach a superscript to an expression.

It uses the following syntax: <msup> base superscript </msup>.

Attributes

This element's attributes include the global MathML attributes as well as the following deprecated attribute:

  • superscriptshift {{deprecated_inline}} {{Non-standard_Inline}}
    • : A {{cssxref("length-percentage")}} indicating the minimum amount to shift the baseline of the superscript up.

[!NOTE] For the superscriptshift attribute, some browsers may also accept legacy MathML lengths.

Examples

html
<math display="block">
  <msup>
    <mi>X</mi>
    <mn>2</mn>
  </msup>
</math>
