Options

precalculate

The precalculate option determines whether values with the same unit
should be precalculated. By default, these are not precalculation.

postcssColorHexAlpha({
  precalculate: true
});

The second and third value has the same unit (px):

.foo {
  width: clamp(10em, 4px, 10px);
}
/* becomes */
.foo {
  width: max(10em, 14px);
}

Here all values have the same unit:

.foo {
  width: clamp(10px, 4px, 10px);
}
/* becomes */
.foo {
  width: 24px;
}
