Using in JavaScript (React)

import typoRhythm from 'typoRhythm'
 
class Hello extends React.Component {
  render() {
    return (
      <h1 style={ typoRhythm(size: 47, margin: 1) } > Hello World </h1>
    )
  }
}

Result

{
  fontSize: "2.9375em",
  padding: null,
  marginBottom: "0.5106382978723404em",
  lineHeight: 1.0212765957446808
}

Change the default base or fontsize:

import {TypoRhythm} from 'typoRhythm'
 
const typoRhythm = new TypoRhythm(14, 32)

Using in Sass

Import typoRhythm in your project

@import 'typorhythm.scss';

Include it in your element

h3 {
  @include typoRhythm(21);
}

TypoRhythm will do the rhythmic math for you in ems and compile to css:

h3 {
  font-size: 1.3125rem;
  line-height: 1.14286em;
}

Change the default base or fontsize:

$typorhythm_base: 24 !default;
$typorhythm_fontsize: 16 !default;

Example:

h3 {
  @include typoRhythm(21, $padding: 1, $margin: 2);
}

h3 {
  font-size: 1.3125em;
  padding: 1.14286em;
  margin-bottom: 2.28571em;
  line-height: 1.14286;
}

@include typoRhythmGenerator($sizeMap, $margin: 1);
