1px解决方案--集锦

没有废话，直接上代码

汇聚各类版本，持续更新中。。。。

1.sass

 1 @charset "utf-8";  2 /**  3  * @module 背景与边框  4  * @description 为元素添加边框（包括1px边框）  5  * @method border  6  * @version 2.0.0  7  * @param {String} $border-width 指定边框厚度（单位为px），默认值：1px，取值与`border-width`属性一致，不一样方向表明边框位置 <2.0.0>  8  * @param {String} $border-color 指定边框颜色 <2.0.0>  9  * @param {String} $border-style 指定边框样式 <2.0.0> 10  * @param {String} $radius 指定边框圆角半径，默认值：null <2.0.0> 11  */
12 @mixin border($border-width: 1px, $border-color: map-get($base, border-color), $border-style: solid, $radius: null) {
13  // 为边框位置提供定位参考 14  position: relative;
15  @if $border-width == null { 16  $border-width: 0;
17     }
18  border-radius: $radius; 19  &::after {
20  // 用以解决边框layer遮盖内容 21  pointer-events: none;
22  position: absolute;
23  z-index: 999;
24  top: 0;
25  left: 0;
26  // fix当元素宽度出现小数时，边框可能显示不全的问题 27  // overflow: hidden;
28  content: "\0020";
29  border-color: $border-color;
30  border-style: $border-style;
31  border-width: $border-width;
32  // 适配dpr进行缩放 33  @include responsive(retina1x) { 34  width: 100%;
35  height: 100%;
36  @if $radius != null { 37  border-radius: $radius;
38             }
39  } 40  @include responsive(retina2x) {
41  width: 200%;
42  height: 200%;
43  @include transform(scale(.5)); 44  @if $radius != null { 45  border-radius: $radius * 2;
46             }
47  } 48  @include responsive(retina3x) {
49  width: 300%;
50  height: 300%;
51  @include transform(scale(.33333)); 52  @if $radius != null { 53  border-radius: $radius * 3;
54             }
55  } 56  @include transform-origin(0 0); 57  } 58 }

2.stylus

border($border-width = 1px, $border-color = #ccc, $border-style = solid, $radius = 0) // 为边框位置提供定位参考 position: relative; if $border-width == null $border-width: 0; border-radius: $radius; &::after // 用以解决边框layer遮盖内容 pointer-events: none; position: absolute; z-index: 999; top: 0; left: 0; // fix当元素宽度出现小数时，边框可能显示不全的问题 // overflow: hidden; content: "\0020"; border-color: $border-color; border-style: $border-style; border-width: $border-width; // 适配dpr进行缩放 @media (max--moz-device-pixel-ratio: 1.49), (-webkit-max-device-pixel-ratio: 1.49), (max-device-pixel-ratio: 1.49), (max-resolution: 143dpi), (max-resolution: 1.49dppx) width: 100%; height: 100%; if $radius != null { border-radius: $radius;
      } @media (min--moz-device-pixel-ratio: 1.5) and (max--moz-device-pixel-ratio: 2.49), (-webkit-min-device-pixel-ratio: 1.5) and (-webkit-max-device-pixel-ratio: 2.49),(min-device-pixel-ratio: 1.5) and (max-device-pixel-ratio: 2.49),(min-resolution: 144dpi) and (max-resolution: 239dpi),(min-resolution: 1.5dppx) and (max-resolution: 2.49dppx) width: 200%; height: 200%; transform: scale(.5) if $radius != null { border-radius: $radius * 2;
      } @media (min--moz-device-pixel-ratio: 2.5), (-webkit-min-device-pixel-ratio: 2.5),(min-device-pixel-ratio: 2.5), (min-resolution: 240dpi),(min-resolution: 2.5dppx) width: 300%; height: 300%; transform: scale(.33333) if $radius != null { border-radius: $radius * 3;
      } transform-origin: 0 0;

 3.react组件中

import styled from 'styled-components' const border = ({ component=null, width='1px', style='solid', color='#ccc', radius=0 }) => { return styled(component) ` position: relative; border-width: ${ width }; border-radius: ${ radius + 'px' }; &::after { pointer-events: none; position: absolute; z-index: 999; top: 0; left: 0; content: ""; border-color: ${ color }; border-style: ${ style }; border-width: ${ width }; @media (max--moz-device-pixel-ratio: 1.49), (-webkit-max-device-pixel-ratio: 1.49), (max-device-pixel-ratio: 1.49), (max-resolution: 143dpi), (max-resolution: 1.49dppx) { width: 100%; height: 100%; border-radius: ${ radius + 'px' }; }; @media (min--moz-device-pixel-ratio: 1.5) and (max--moz-device-pixel-ratio: 2.49), (-webkit-min-device-pixel-ratio: 1.5) and (-webkit-max-device-pixel-ratio: 2.49), (min-device-pixel-ratio: 1.5) and (max-device-pixel-ratio: 2.49), (min-resolution: 144dpi) and (max-resolution: 239dpi), (min-resolution: 1.5dppx) and (max-resolution: 2.49dppx) { width: 200%; height: 200%; transform: scale(.5); border-radius: ${ radius * 2 + 'px'}; }; @media (min--moz-device-pixel-ratio: 2.5), (-webkit-min-device-pixel-ratio: 2.5), (min-device-pixel-ratio: 2.5), (min-resolution: 240dpi), (min-resolution: 2.5dppx) { width: 300%; height: 300%; transform: scale(.33333); border-radius: ${ radius * 3 + 'px' } }; transform-origin: 0 0; }; ` } export default border
