如何在 SCSS 中使用多个 @include? [英] How Can I Use Multiple @include in SCSS?

问题描述

我想在同一个 SCSS 中使用多个 include.例如:

I want to use multiple include in the same SCSS. For example:

.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;
    }
}

经常使用多个@include 很无聊.有什么方法可以减少代码，我想用:

it's very Boring to Multiple @include frequently. Have Any Way to Reduce The Code, I want to use:

.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.

But It's Not Valid SCSS. Please Tell Me Another Way To Reduce The Code.

推荐答案

正如@karthick 所提到的，不支持动态包含(目前).在您的情况下，我认为有一个 mixin 来处理所有媒体查询是有意义的 - 例如:

As mentioned by @karthick dynamic includes are not supported (yet). In your case I think it would make sense to have a single mixin to handle all media queries – like:

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; 
  } 
}
