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{}
}
