Steps to split and compress CSS with webpack and import it with link

import $ from 'jquery'
import './css/index.css'
import './less/index.less'
$(function () {
    $('#app li:nth-child(odd)').css('color', 'red')
    $('#app li:nth-child(even)').css('color', 'green')
})
 
import './assets/fonts/iconfont.css';
const ul = document.querySelector("ul");
const theI = document.createElement("li");
theI.className='iconfont icon-qq';
ul.appendChild(theI);
