A plugin to provide a modular scale function in your styles.

Install

npm install postcss-modular-scale

Usage

To generate relative values use target / base font size

Example:

1 = 16px ( target ) / 16px ( base font size )
0.75 = 12px ( target ) / 16px ( base font size )
Generates `em` or `rem` relative values

Input

:root {
  --ms-bases: 1, 0.75;
  --ms-ratios: 2;
}
.header {
  font-size: ms(4)rem;
}

Output

:root {
  --ms-bases: 1, 0.75;
  --ms-ratios: 2;
}
.header {
  font-size: 3rem;
}
