This repository is a plug in for [Tailwindcss](https://github.com/tailwindlabs/tailwindcss) 

 Installation
--
Install the plugin via npm:

    npm install tailwind-nth-child

tailwind.config.js
--
Create an instance like this.
``` js
const Nth =  require('tailwind-nth-child');
const <name_suffix> =  new  Nth('<name_suffix>','<nth-value>')
module.exports = {
// ...
variants: {
    // extend the backgroundColor variants
    extend:{
      backgroundColor: ['nth-child-<name_suffix>'],
    }
},
plugins: [
    <name_suffix>.nthChild() // add-plugin
],

const nth2n =  new  Nth('2n','2n+0') // Sub-elements that are multiples of 2  === new  Nth('even','even')
const nth5 =  new  Nth('5','-n+5') // The first five child elements
const nth4 =  new  Nth('4','-n+4') // The first four child elements

module.exports = {
// ...
variants: {
    // extend the backgroundColor variants
