【Sass】混入mixin

mixin就相當於js中的函數，對一些樣式進行了封裝，減少代碼的編寫。

混合宏無法重載，參數可以設置默認值。

<template>
  <div id="app">
    <div></div>
    <div></div>
    <div></div>
  </div>
</template>

<script>
    export default {
        name: 'App'
    }
</script>

<style lang="scss">
  //無參混合宏
  @mixin app-border{
    border: 1px solid red;
    border-radius: 4px;
  }
  //帶參混合宏
  @mixin div-border($radius,$boder-size:2px){
    border: $boder-size solid blue;
    border-radius: $radius;
  }

  #app{
    @include app-border;
    height: 100px;
    display: flex;
    justify-content: space-around;
    align-items: center;
    
    div{
      @include div-border(50%);
      height: 50px;
      width: 50px;
    }
  }

</style>
