ko-modular-scale($font-size-base, 1, $type-scale)
ko-modular-scale($font-size-base, 3, $type-scale)


// or using this shorthand, we assume that `$font-size-base` & `$type-scale` are already set somewhere (in Kickoff, they are set in the _variables.scss file):
$font-size-base: 20;
$type-scale: 1.4

ko-ms(-1)
ko-ms(1)
ko-ms(3)
