问题

1. css background属性连写

background：#fff  url('../assets/images/bgc_book.png') no-repeat right top/359px 257px,
background: url('../assets/images/bgc_pc.png') no-repeat 130px 220px/347px 246px;

background: url("../../assets/images/logo.png") no-repeat 0 0/100% 100% ;

依次的顺序为：背景颜色 背景图片 背景图片是否重复 背景图片的位置（位置可用像素及方位名称）/背景图片的宽高，下一个背景图片的属性

2. vue 中的轮播图：使用swiper

 npm i  vue-awesome-swiper@2.6.7 --save

swiper.vue组件

<template>
  <div class="swiper3">
    <swiper :options="swiperOption">
      <swiper-slide v-for="(item, index) in giftType" :key="index">
        <div class="gift-type" :data-id="item.id">
          <img :src="item.img" alt="">
          <!--<p>{{item.detail1}}</p>-->
          <p class="point-text" style="height: 0.1rem;">{{item.detail2}}</p>
        </div>
      </swiper-slide>
    </swiper>
  </div>
</template>

<script>

3. vue子组件定义属性 

props

props: []

或者

props: {
  options: {
    type: Object,
    default: _=>{}
  },
  link: String
}
