    font-size: percentage($fontSize / $baseFontSize);
}

レスポンシブ用(rem使用)

  font-size: $size + px;
  font-size: ($size / $base) * 1rem;
}

    line-height: percentage($lineHeight / $baseFontSize);
}

  @p-size-retina: @p-size * 2;
  @percent: ((@p-size-retina / @page) * 100);
  width: ~'@{percent}%';
  @pd-size: (100 - @percent) / 2;
  padding-left: ~'@{pd-size}%';
  padding-right: ~'@{pd-size}%';
}

左右marginにて調整

.cntWidthCenter(@p-size1: 0, @page1: 640){
  @p-size-retina1: @p-size1 * 2;
  @percent1: ((@p-size-retina1 / @page1) * 100);
