viewport模板

特殊机型适配

iPhoneX，作为唯一有刘海手机，对页面适配带来了问题，可以用如下代码适配iPhoneX。

/* iPhoneX适配 */
@media only screen and (device-width: 375px) and (device-height: 812px) and (-webkit-device-pixel-ratio: 3) { 
.class{}
}

iPhone4，作为窄屏手机，分辨率为960x640，web窗口的高度仅有832px，容易引起适配的问题，如页面的主体按钮被隐藏在屏幕外，通常需要对它做特殊适配

/* 适配iPhone4 */
@media (device-height:480px) and (-webkit-min-device-pixel-ratio:2){
.class{}
}
