Device Related Classes

Also this Device detecting library adds additional classes on <html> element which can help you with different CSS styles for different OS and platforms.

So if you open app with iOS 7.1 device you may have the following classes:

<html class="ios device-ios device-ios-7 device-ios-7-1 device-ios-gt-6 device-pixel-ratio-1">
...

If you open app with iOS 7.1 device with retina screen and your app running in full screen mode:

<html class="device-ios device-ios-7 device-ios-7-1 device-ios-gt-6 device-retina device-pixel-ratio-2 with-statusbar">
...

If you open app on iPhone X and your app running in full screen mode:

<html class="device-ios device-iphone-x device-ios-11 device-ios-11-0 device-ios-gt-6 device-ios-gt-7 device-ios-gt-8 device-ios-gt-9 device-ios-gt-10 device-retina device-pixel-ratio-3 with-statusbar">
...

If you open app with Android 4.4 device you will have the following classes:

<html class="device-android device-android-4 device-android-4-4">
...

In other words classes calculated by the following rule:

device-[os]
device-[os major version]
device-[os full version]
[device-desktop]
[device-retina]
[device-iphone-x] - if it is iPhone X
[device-desktop]
[device-macos] - if desktop macOS device
[device-windows] - if desktop windows device
device-pixel-ratio-[pixel ratio]
[with-statusbar] - in case the app is running in full screen mode

Note that “greater than” (ios-gt-6: for all iOS greater than iOS 6) classes available only for iOS
