Question

我想在同一个scs中使用多个include。例如

.section-ptb {
    padding-top: 130px;
    padding-bottom: 130px;
    @include desktop {
        padding-top: 80px;
        padding-bottom: 80px;
    }
    @include tablet {
        padding-top: 80px;
        padding-bottom: 80px;
    }
    @include mobole {
        padding-top: 80px;
        padding-bottom: 80px;
    }
}

经常对多个@include很无聊。有什么办法可以减少代码，我想使用

.section-ptb {
    padding-top: 130px;
    padding-bottom: 130px;
    @include desktop , @include tablet, @include mobole {
        padding-top: 80px;
        padding-bottom: 80px;
    }
}

但这不是有效的SCSS。请告诉我另一种减少代码的方法。

如@karthick所述，尚不支持动态包含。对于您的情况，我认为只有一个mixin来处理所有媒体查询是很有意义的，例如：

SCSS

//  map holding breakpoint values
$breakpoints: (
  mobile : 0px, 
  tablet : 680px, 
  desktop: 960px
);

//  mixin to print out media queries (based on map keys passed) 
@mixin media($keys...){
  @each $key in $keys { 
    @media (min-width: map-get($breakpoints, $key)){
      @content
    } 
  }
}



.section-ptb {
  padding-top: 130px;
  padding-bottom: 130px;

  //  pass the key(s) of the media queries you want to print  
  @include media(mobile, tablet, desktop){
    padding-top: 80px;
    padding-bottom: 80px;
  }
}

CSS输出

.section-ptb {
  padding-top: 130px;
  padding-bottom: 130px; 
}
@media (min-width: 0px) {
  .section-ptb {
    padding-top: 80px;
    padding-bottom: 80px; 
  } 
}
@media (min-width: 680px) {
  .section-ptb {
    padding-top: 80px;
    padding-bottom: 80px; 
  } 
}
@media (min-width: 960px) {
  .section-ptb {
    padding-top: 80px;
    padding-bottom: 80px; 
  } 
}

你可以这样使用：

SCSS

@mixin media($keys...) {
  @each $key in $keys {
    @if ($key == phone) {
      @include phone {
        @content
      }
    } @else if ($key == tablet) {
      @include tablet {
        @content
      }
    } @else if ($key == desktop) {
      @include desktop {
        @content
      }
    }
  }
}

用法

@include media(phone, tablet, desktop) {
  // your scss code
}

@include media(tablet, desktop) {
  // your scss code
}

@include media(phone) {
  // your scss code
}

// and so on...

如何在SCSS中使用多个@include？
