对 lib-flexible 进行了改造（其实就加了两行代码，见commit），更简单易用。

原理

3.75 为设计稿宽度/100,现在所有适口都是理想视口，设备宽度/设计稿宽度为 css 宽度的放大倍数，根据rem 的特性，将HTML的 font-size设置为该值，又因 HTML font-size 最小为 12px，故将该倍数乘以 100。相应css 尺寸则为设计稿内的宽度/100 rem.

1px 解决方案

@minxin border($width,$style,$color) {
  [data-dpr='1'] & {
    border: $width $style $color;
  }
  [data-dpr='2'] & {
    border: $width/2 $style $color;
  }
 [data-dpr='1'] & {
    border: $width/3 $style $color;
  }
}
