sass动态实现颜色平铺显示

@function stripes($position,$colors) {
  $colors: if(type-of($colors)!='list', compact($colors), $colors);
  $gradient: compact();
  $len: length($colors);
  $ percentage(1 / $len);

  @for $i from 1 through $len {
    $current-color: nth($colors, $i);
    $temp: $current-color ($width * ($i - 1)), $current-color ($width * $i);
    $gradient: join($gradient, $temp, comma);
  }
  @return linear-gradient($position, $gradient);
}

$pop-stripe-color:red orange yellow green blue purple...;
