Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The math-shift property indicates whether superscripts inside MathML formulas should be raised by a normal or compact shift.

Syntax

css
/* Keyword values */
math-shift: normal;
math-shift: compact;

/* Global values */
math-shift: inherit;
math-shift: initial;
math-shift: revert;
math-shift: revert-layer;
math-shift: unset;

Values

normal

The initial value, indicates normal rendering. Superscripts in MathML formulas use the superscriptShiftUp parameter from the OpenType MATH table.

compact

Indicates compact rendering. Superscripts in MathML formulas use the superscriptShiftUpCramped parameter from the OpenType MATH table, which is generally smaller.

MathML

The following MathML displays two versions of "x squared" using a font with an OpenType MATH table. Browser implementing the math-shift property should raise the superscripts using slightly different shifts.

html
<math style="font-size: 64pt;">
  <msup style="math-shift: normal">
    <mi>x</mi>
    <mn>2</mn>
  </msup>
  <msup style="math-shift: compact">
    <mi>x</mi>
    <mn>2</mn>
  </msup>
</math>
