Normal and compact shift

The following MathML displays two versions of "x squared" using a font with an OpenType MATH table. The math-shift property is used to raise the superscripts using the normal and compact shift.

CSS

css
math {
  font-size: 64pt;
  math-shift: normal;
}

.compact-shift {
  math-shift: compact;
}

MathML

html
<math>
  <msup>
    <mi>x</mi>
    <mn>2</mn>
  </msup>
  <msup class="compact-shift">
    <mi>x</mi>
    <mn>2</mn>
  </msup>
</math>

Results

Note that the second "2" has a more compact (lower) shift.
