写一个头部组件

<template>
    <header class="header">
      <slot name="left"></slot> //插槽占位   识别用不同的name属性
      <a class="header_title">
        <span class="header_title_text ellipsis">{{title}}</span>
      </a>
      <slot name="right"></slot>
    </header>
</template>
<script>

export default {
     props: {
      title:String   //接收属性
    },
}
</script>
<style lang="stylus" scoped>
    .header
      background-color #02a774
      position fixed
      z-index 100
      left 0
      top 0
      width 100%
      height 45px
      .header_search
        position absolute
        left 15px
        top 50%
        transform translateY(-50%)
        width 10%
        height 50%
        .icon-sousuo
          font-size 25px
          color #fff
      .header_title
        position absolute
        top 50%
        left 50%
        transform translate(-50%, -50%)
        width 50%
        color #fff
        text-align center
      .header_title_text
          font-size 20px
          color #fff
          display block
      .header_login
        font-size 14px
        color #fff
        position absolute
        right 15px
        top 50%
        transform translateY(-50%)
      .header_login_text
          color #fff
</style>

怎么用

<template>
  <div class="msite">
    <!--首页头部-->
    <HeaderTop :title="address.name">  //传title值
      <a class="header_search" slot="left">   left对应的name属性slot标签
        <i class="iconfont icon-sousuo"></i>
      </a>
      <a class="header_login" slot="right">  right对应的name属性slot标签
        <span class="header_login_text">登录|注册</span>
      </a>
    </HeaderTop>
    </template>
    import HeaderTop from "../../components/HeaderTop/HeaderTop.vue" //引入
    export default {
    components: {
    HeaderTop, //印射成标签
  }
}
