flex布局样式 类名化scss(sass)

sass 和less 语法有差异需要转化一下

$directionList: row, row-reverse, column, column-reverse;
$justifyContentList: flex-start, flex-end, center, space-between, space-around, space-evenly;
$alignItemsList: flex-start, flex-end, center, baseline, stretch;

@mixin generateFlex($dr, $JC, $AI, $dir, $jc, $ai) {
  @if ($ai == center) {
    // flex-x-center
    .flex-#{$dr}-#{$JC} {
      display: flex;
      flex-direction: $dir;
      justify-content: $jc;
      align-items: center;
    }
  } @else {
    .flex-#{$dr}-#{$JC}-#{$AI} {
      display: flex;
      flex-direction: $dir;
      justify-content: $jc;
      align-items: $ai;
    }
  }
}
 
@each $dir in $directionList {
  $dr: if($dir == row, x, if($dir == column, y, $dir));
  
  @each $jc in $justifyContentList {
    $JC: if($jc == flex-start, start, if($jc == flex-end, end, if($jc == space-between, between, if($jc == space-evenly, evenly, if($jc == space-around, around, $jc)))));
    
    @each $ai in $alignItemsList {
      $AI: if($ai == flex-start, start, if($ai == flex-end, end, $ai));
      
      @include generateFlex($dr, $JC, $AI, $dir, $jc, $ai);
    }
  }
}
