移动端H5页面兼容性问题小结
1. input框 边框的在ios下颜色变淡问题
input:disabled{
border: 1px solid #017BBA;
-webkit-opacity:1;
opacity: 1;
}
2. iphone7下 横屏之后字体变大
css中加入以下代码：
@media screen and (max-device-width: 320px){body{-webkit-text-size-adjust:100%}}
@media screen and (max-device-width: 480px){body{-webkit-text-size-adjust:100%}}
@media only screen and (-webkit-min-device-pixel-ratio: 2){body{-webkit-text-size-adjust:100%}}
如何没有效果，就单独在标签上设置样式 -webkit-text-size-adjust:100%
3. H5页面禁止横屏
uc浏览器强制竖屏
<meta name="screen-orientation" content="portrait">
QQ浏览器强制竖屏
<meta name="x5-orientation" content="portrait">
iphone safari浏览器没有查到可以使用meta，以上应该会有兼容性问题（没有测），我是使用的是js方法，当横屏的时候显示一个页面，告诉用户“为了您的良好体验，请使用竖屏”
js方式

css中需添加一个样式：
.rotateScreenClass{
display: none;
}
4. ORC上传身份证正反面时，如果用户手机水平与地面拍照时，横屏或者竖屏拍身份证会出现上传的图片显示不正常（还没解决。。。）
试过的方法：引入exif.js,获取到Orientation的值，根据Orientation的值进行判断旋转
此种方法适用于手机垂直或与地面有角度时，即当手机水平与地面拍照时，是没有横屏和竖屏之分的，没有办法判断方向
