What are the CSS media queries corresponding to Apple's new devices ? I need to set the body's background-color to change the X's safe area background color.

回答1:

iPhone X

@media only screen 
    and (device-width : 375px) 
    and (device-height : 812px) 
    and (-webkit-device-pixel-ratio : 3) { }

iPhone 8

@media only screen 
    and (device-width : 375px) 
    and (device-height : 667px) 
    and (-webkit-device-pixel-ratio : 2) { }

iPhone 8 Plus

@media only screen 
    and (device-width : 414px) 
    and (device-height : 736px) 
    and (-webkit-device-pixel-ratio : 3) { }

iPhone 6+/6s+/7+/8+ share the same sizes, while the iPhone 7/8 also do.

Looking for a specific orientation ?

Portrait

Add the following rule:

    and (orientation : portrait)

Landscape

Add the following rule:

    and (orientation : landscape)

I noticed that the answers here are using: device-width, device-height, min-device-width, min-device-height, max-device-width, max-device-height.

Please refrain from using them since they are deprecated. see MDN for reference. Instead use the regular min-width, max-width and so on. For extra assurance, you can set the min and max to the same px amount. For example:

iPhone X

@media only screen 
    and (width : 375px) 
    and (height : 635px)
    and (orientation : portrait)  
    and (-webkit-device-pixel-ratio : 3) { }

You may also notice that I am using 635px for height. Try it yourself the window height is actually 635px. run iOS simulator for iPhone X and in Safari Web inspector do window.innerHeight. Here are a few useful links on this subject:

It seems that the most accurate (and seamless) method of adding the padding for iPhone X/8 using env()...

padding: env(safe-area-inset-top) env(safe-area-inset-right) env(safe-area-inset-bottom) env(safe-area-inset-left);

Here's a link describing this:

If your page is missing meta[@name="viewport"] element within its DOM, then the following could be used to detect a mobile device:

@media only screen and (width: 980px), (hover: none) { … }

If you want to avoid false-positives with desktops that just magically have their viewport set to 980px like all the mobile browsers do, then a device-width test could also be added into the mix:

@media only screen and (max-device-width: 800px) and (width: 980px), (hover: none) { … }

Per the list at https://developer.mozilla.org/en-US/docs/Web/CSS/Media_Queries/Using_media_queries, the new hover property would appear to be the final new way to detect that you've got yourself a mobile device that doesn't really do proper hover; it's only been introduced in 2018 with Firefox 64 (2018), although it's been supported since 2016 with Android Chrome 50 (2016), or even since 2014 with Chrome 38 (2014):
