-webkit-overflow-scrolling 实现快速滚动和回弹
HTML5网页内都有快速滚动和回弹的效果，看上去和原生app的效率都有得一拼。
实现方式：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<meta name="viewport"
content="width=device-width,initial-scale=1, maximum-scale=1, minimum-scale=1, user-scalable=no">
<title>scroll</title>
<style type="text/css">
*{margin: 0;padding: 0;}
header{
background: #f00;
color: #fff;
}
nav {
width: 85%;
height: 30px;
line-height: 30px;
white-space: nowrap;
overflow: hidden;
overflow-x: scroll;
-webkit-overflow-scrolling: touch;
}
nav::-webkit-scrollbar {
display: none;
}
nav a {
display: inline-block;
width: 50px;
height: 30px;
}
</style>
</head>
<body>
<header>
<nav>
<a>菜单1</a>
<a>菜单2</a>
<a>菜单3</a>
<a>菜单4</a>
<a>菜单5</a>
<a>菜单6</a>
<a>菜单7</a>
<a>菜单8</a>
<a>菜单9</a>
<a>菜单10</a>
</nav>
</header>
</body>
</html>
