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)
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),

width: 100%;

省略点ellipsis的解决方案（支持多行）
wrap($is-wrap = true)
if $is-wrap == true
word-wrap: break-word;
word-break: break-all;
else
white-space: nowrap; ellipsis($width = null, $line-clamp = 1)
overflow: hidden;
text-overflow: ellipsis;
width: $width;
if abs($line-clamp) > 1
// 要使得多行截取生效，display的值只能为-webkit-box
display: -webkit-box !important;
-webkit-line-clamp: $line-clamp;
flex-direction column
wrap()
else
wrap(false)
将上述代码放入styl文件中，就可以直接使用！
