vue 横向 简单实用版本 时间轴------ Timeline

由于之前弄了一个带左右按钮时间轴，里面问题太多，

改版

<template>
  <div class="hello">
    <ul :style="actived">
      <!-- <ul :style="{ marginLeft: left + 'px', width: widthUl + 'px' }"> -->

      <li
        v-for="(item, i) in month"
        :key="i++"

        :style="{ width: widthLi + 'px' }"
        :class="{ active: isActive == i }"
