我找到過方法，但是不知道怎么用，代碼如下：%border-1px{display:block;position:absolute;left:0;width:100%;content:'';}.border-1px{position:relative;&::after{@extend%border-1px;bottom:0;border-top:1pxsolid#ccc;}&::before{@extend%border-1px;top:0;border-bottom:1pxsolid#ccc;}}@media(-webkit-min-device-pixel-ratio:1.5),(min-device-pixel-ratio:1.5){.border-1px{&::after{-webkit-transform:scaleY(0.7);transform:scaleY(0.7);}}}@media(-webkit-min-device-pixel-ratio:2),(min-device-pixel-ratio:2){.border-1px{&::after{-webkit-transform:scaleY(0.5);transform:scaleY(0.5);}}}
移動前端設置border為1px顯得粗
達令說
