【问题描述】：

我想创建自己的框架，例如 bootstrap。但是我遇到了一个问题。我创建了媒体查询部分，但我无法使用 Sass 技术进行循环。我想创建一个循环来执行以下操作

@media (min-width: #/*there is the first loop (576px,768px,992px ..)*/) 
   .grid-col-#/*this is loop two (i want to loop all sizes such (mid, xl, xxl))*/ 
       display: grid;
       grid-template-columns: repeat(#/*i want here to make loop does take a lot of 
       numbers such as (1, 2, 3, 4, 5, 6 ..) 
       of columns*/,minmax(0, 1fr));
   

这个想法是让一种媒体重复，直到它承载所有尺寸的屏幕，就像这样

@media (min-width: 557px) 
      .grid-col-sm-1 
        display: grid;
        grid-template-columns: repeat(1 /*the number in the class*/, minmax(0, 1fr))
       
     .grdi-col-sm-2 
       display: grid;
       grid-template-columns: repeat(2, minmax(0, 1fr))
     
    
@media (min-width: 768px) 
   .grid-col-md-1 
      display: grid;
      grid-template-columns: repeat(1, minmax(0, 1fr))
   
   .grid-col-md-2 
     display: grid;
     grid-template-columns: repeat(2, minmax(0, 1fr))
   

我希望我解释得很好。我想发展我的基本技能，仅此而已。

【问题讨论】：

你知道 sass 中的“@each”吗？文档示例：sass-lang.com/documentation/values/lists

【参考方案1】：

你想要这样的东西：

$breakpoints : '575px','768px','992px','1200px';

@each $breakpoint in $breakpoints 
    @media (min-width: #$breakpoint ) 
        @for $i from 1 through 12 
           .grid-col-#$i 
               display: grid;
               grid-template-columns: repeat( #$i,minmax(0, 1fr));
            
        
    

这将输出：

@media (min-width: 575px) 
  .grid-col-1 
    display: grid;
    grid-template-columns: repeat(1, minmax(0, 1fr));
  

  .grid-col-2

    grid-template-columns: repeat(2, minmax(0, 1fr));

    grid-template-columns: repeat(3, minmax(0, 1fr));
