jss-default-unit v8.0.2

JSS plugin that adds default custom unit to numeric values where needed

JSS plugin that adds units to numeric values


Provide plain numeric values in your JSS style definitions, and the plugin will insert the apposite units. Defaults to px for sizes, ms for durations, and % for transform origins, and these can be customized easily (see Usage Example).

Make sure you read how to use plugins in general.


import jss from 'jss'
import defaultUnit from 'jss-default-unit'

// Optionally you can customize default units.
const options = {
  'line-height': 'rem',
  'font-size': 'rem'



const styles = {
  container: {
    'line-height': 3,
    'font-size': 1.7,
    'height': 200,
    'z-index': 1

Compiles to:

.container-sdf345 {
  line-height: 3rem;
  font-size: 1.7rem;
  height: 200px;
  z-index: 1;
