移动端上经常发现1px边框异常的粗,因此,决定用伪类配合css3来实现0.5px边框
代码如下:
1 <!doctype html> 2 <html lang="en"> 3 <head> 4 <meta content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=0" name="viewport"> 5 <meta charset="UTF-8"> 6 <title>0.5 border</title> 7 <style type="text/css"> 8 *{margin: 0;padding: 0;-webkit-box-sizing:border-box;} 9 ul{ 10 position: relative; 11 } 12 li{ 13 height: 60px; 14 line-height: 60px; 15 padding-left: 10px; 16 position: relative; 17 font-size: 20px; 18 } 19 li:after{ 20 content: ""; 21 display: block; 22 position: absolute; 23 left: -50%; 24 width: 200%; 25 height: 1px; 26 background: #ededed; 27 -webkit-transform:scale(0.5); 28 } 29 </style> 30 </head> 31 <body> 32 <ul> 33 <li>list-item1</li> 34 <li>list-item2</li> 35 <li>list-item3</li> 36 <li>list-item4</li> 37 <li>list-item5</li> 38 <li>list-item6</li> 39 <li>list-item7</li> 40 <li>list-item8</li> 41 </ul> 42 </body> 43 </html>
主要思路是利用伪类来实现border,先放大一倍,再利用css3缩小一倍。再用定位定到正确的位置即可
