本文章向大家介绍关于移动端一像素线的解决方案,需要的朋友可以参考一下

引用了yo框架中的_border.scss(用来获取yo框架封装的border)   以及   variables.scss(用来获取媒体查询的规则)

 1 border($border-width = 1px, $border-color = #ccc, $border-style = solid, $radius = 0)
 2   // 为边框位置提供定位参考
 3   position: relative;
 4 
 5   if $border-width == null
 6     $border-width: 0;
 7 
 8   border-radius: $radius;
 9 
10   &::after
11     // 用以解决边框layer遮盖内容
12     pointer-events: none;
13     position: absolute;
14     z-index: 999;
15     top: 0;
16     left: 0;
17     // fix当元素宽度出现小数时,边框可能显示不全的问题
18     // overflow: hidden;
19     content: "\0020";
20     border-color: $border-color;
21     border-style: $border-style;
22     border-width: $border-width;
23     
24     // 适配dpr进行缩放
25     @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)
26       width: 100%;
27       height: 100%;
28       if $radius != null {
29         border-radius: $radius;
30       }
31     
32     @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)
33       width: 200%;
34       height: 200%;
35       transform: scale(.5)
36       if $radius != null {
37         border-radius: $radius * 2;
38       }
39     
40     @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)
41       width: 300%;
42       height: 300%;
43       transform: scale(.33333)
44       if $radius != null {
45         border-radius: $radius * 3;
46       }
47 
48     transform-origin: 0 0;

省略点ellipsis的解决方案(支持多行)

 1 wrap($is-wrap = true)
 2   if $is-wrap == true
 3     word-wrap: break-word;
 4     word-break: break-all;
 5   else
 6     white-space: nowrap;
 7     
 9 ellipsis($width = null, $line-clamp = 1) 
10   overflow: hidden;
11   text-overflow: ellipsis;
12   width: $width;
13   if abs($line-clamp) > 1
14     // 要使得多行截取生效,display的值只能为-webkit-box
15     display: -webkit-box !important;
16     -webkit-line-clamp: $line-clamp;
17     flex-direction column
18     wrap()
19   else
20     wrap(false)

将上述代码放入styl文件中,就可以直接使用!
