1.不用修改官网中任何css或者html

2.按需引入，不是只是引入官网的就可以

import Vue from 'vue'
import Router from 'vue-router'
import HelloWorld from '@/components/HelloWorld'
import First from '@/components/views/First'
import Second from '@/components/views/Second'
import Index from '@/components/views/Index'
import {Container,Header,Main} from 'element-ui'



Vue.use(Router)
Vue.use(Container)
Vue.use(Header)
Vue.use(Main)


export default new Router({
  routes: [
    {
      path: '/',
      name: 'HelloWorld',
      component: HelloWorld
    }, {
      path: '/first',
      name: 'First',
      component: First
    }, {
      path: '/second',
      name: 'Second',
      component: Second
    }, {
      path: '/index',
      name: 'Index',
      component: Index
    }
  ]
})

就可以啦
