前段时间做了一个浮层,但在ios上,浮层滑动不流畅,基本上是随着手指的移动而移动,经研究加上-webkit-overflow-scrolling: touch即可
eg:
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> <meta name="keywords" content="尚德机构"/> <meta name="description" content="尚德机构"/> <meta name="apple-mobile-web-app-capable" content="yes"/> <meta name="generator" content="bd-mobcard"/> <meta name="viewport" content="maximum-scale=1.0,minimum-scale=1.0,user-scalable=0,width=device-width,initial-scale=1.0"/> <title></title> <style type="text/css"> #a { width: 100%; height: 100%; position: fixed; top: 0; left: 0; font-size: 20px; white-space: pre; background: lightgoldenrodyellow; overflow-y: scroll; -webkit-overflow-scrolling: touch; } #b { } </style> </head> <body> <div id="a"> <div id="b"> 1 1 1 1 11 1 1 1 11 1 11 1 1 11 1 1 1 1 11 1 11 11 111111 1 1 1 1 1 1 1 1 1 1 1 1 </div> </div> </body> </html>
本质上,此属性创建了带有硬件加速的系统级控件,使元素能快速滑动和回弹,同时也会消耗更多的内存。
