(2) Media query
1. Use the constant function
The constant function can only be used if viewport-fit=cover is set
@supports(bottom:constant(safe-area-inset-bottom)) {
selector{
padding-bottom:constant(safe-area-inset-bottom);
padding-bottom:calc(30px(假设值) + constant(safe-area-inset-bottom)); //根据实际情况选择适配方法
}
}2.Use iphoneX Unique model parameters
@media only screen and (device-width: 375px) and (device-height:812px) and (-webkit-device-pixel-ratio:3) {
#buy {
padding-bottom:34px;
}
}(3) js judgment (Jquery is used below)
if($(window).width() === 375 && $(window).height() === 724 && window.devicePixelRatio === 3){
#buy {
padding-bottom:34px;
}
}(4) Client protocol
can also be requested according to the client protocol The client queries whether it is an iphoneX to keep it consistent with the client.
4. Parameter explanation

- 375 — Width of iphoneX device
- 812 —Height of iphoneX device
- 3 — Resolution of iphoneX device
- 724 — Height of iphoneX device (812) - Top bar height (88)
- 34 — Bottom safety area height
