PostCSS Vertical Rhythm Function

PostCSS plugin to use vertical rhythm by providing a unit-agnostic vr() function.

How is this different from postcss-vertical-rhythm?

This plugin allows you to use your own units (px, rem, em, etc). vr() is unitless.
You can use line-height or font to define your line-height.
This plugin works well in cases where the font-size is unknown and cannot be used to compute an exact vertical rhythm during build time. An example is the postcss-responsive-type plugin which generates rules to resize your type using the browser's width.

body {
  font-size: 100%;
  line-height: 2;
}

.test {
  padding: vr(1)rem;
}

body {
  font-size: 100%;
  line-height: 2;
}

.test {
  padding: 2rem;
}

Usage

postcss([ require('postcss-vertical-rhythm-function') ])
