<template>
  <div class="block">
    <span class="demonstration">默认 Hover 指示器触发</span>
    <el-carousel height="150px">
      <el-carousel-item v-for="item in 4" :key="item">
        <h3>{
         
  { item }}</h3>
      </el-carousel-item>
    </el-carousel>
  </div>
  <div class="block">
    <span class="demonstration">Click 指示器触发</span>
    <el-carousel trigger="click" height="150px">
      <el-carousel-item v-for="item in 4" :key="item">
        <h3>{
         
  { item }}</h3>
      </el-carousel-item>
    </el-carousel>
  </div>
</template>

<style>
  .el-carousel__item h3 {
    color: #475669;
    font-size: 14px;
    opacity: 0.75;
    line-height: 150px;
    margin: 0;
  }

  .el-carousel__item:nth-child(2n) {
     background-color: #99a9bf;
  }
  
  .el-carousel__item:nth-child(2n+1) {
     background-color: #d3dce6;
  }
</style>

结合使用el-carousel和el-carousel-item标签就得到了一个走马灯。幻灯片的内容是任意的，需要放在el-carousel-item标签中。默认情况下，在鼠标 hover 底部的指示器时就会触发切换。通过设置trigger属性为click，可以达到点击触发的效果。
