移动混合开发之android文件管理新建文件和删除文件
今天经过一天超过8小时的实践，有很多CSS上的细节需要注意：
1，
/*注意是对before的操作*/
.content ul li .icon-check-empty:before{
display: block;
/*webFont设置其width和height时无效,只有设置font-size*/
/*width: 3rem;*/
/*height: 3rem;*/
font-size: 1.5rem;
position: absolute;
top:0;
left: 0;
bottom: 0;
padding: .75rem;
}
2.选择器的优先级
/*估计这个优先级没有 .down a{}的高,所以根本没执行
a.btn{} > .down a{} > .down a.btn{}
*/
/*.down a.btn{*/
/*background: lavender;*/
/*border: solid 1px grey;*/
/*border-radius: 5px;*/
/*padding: 5px;*/
/*}*/
.opeator a{
/*使用felx:1让内容平均分布*/
flex:1;
-webkit-box-flex: 1;
/*把webFont当作字体处理,字体居中*/
text-align: center;
text-decoration: none;
display: block;
}
3.动画的设置
需要设置一个初始状态和结束状态，
.opeator{
position: absolute;
bottom: 0;
left: 0;
right: 0;
height: 3rem;
/*容器使用 display:felx属性*/
display:flex;
display: -webkit-flex; /* */
/*注意是transform*/
transition:-webkit-transform 0.3s ease-in;
transform: translateY(0) translateZ(0);
}
.opeator.down {
transform: translateY(3rem) translateZ(0);
}

Some notes:
* gap: is required only on iOS (when using UIWebView) and is needed for JS->native communication
* https://ssl.gstatic.com is required only on Android and is needed for TalkBack to function properly
* Disables use of inline scripts in order to mitigate risk of XSS vulnerabilities. To change this:
* Enable inline JS: add 'unsafe-inline' to default-src
