Collections SASS-将集合作为参数传递给SASS mixin

如何将集合传递给sass mixin

=media($type1, $size1: null)
  @if ($type1) and ($size1)
    @media ($type1: $size1)
      @content
  @elseif ($type1) and not ($size1)
    $collection: $type1
    @media (nth($collection, 1): nth($collection, 2)) <-- ERROR
      @content
  @else
    @error "Upsss...."

=媒体（$type1，$size1:null）
@如果（$type1）和（$size1）
@介质（$type1:$size1）
@内容
@elseif（$type1）和not（$size1）
$collection:$type1
@媒体（第n（$collection，1）：第n（$collection，2））已排序。我必须使用#{map get（$collection，$key name）}函数

=media($type1, $size1: null)
  @if ($type1) and ($size1)
    @media ($type1: $size1)
      @content
  @elseif ($type1) and not ($size1)
    $collection: $type1
    @media (#{map-get($collection, "type1")}: #{map-get($collection, "size1")})
      @content
  @else
    @error "Upsss...."

=media($type1, $size1: null)
  @if ($type1) and ($size1)
    @media ($type1: $size1)
      @content
  @elseif ($type1) and not ($size1)
    $collection: $type1
    @media (#{map-get($collection, "type1")}: #{map-get($collection, "size1")})
      @content
  @else
    @error "Upsss...."
