我一直在做一些关于媒体查询的研究，但我仍然不太明白如何针对特定尺寸的设备。
我希望能够瞄准台式机、平板电脑和手机。我知道会有一些差异，但如果有一个通用的系统可以用来针对这些设备就好了。
我找到了一些例子:
# Mobile
only screen and (min-width: 480px)
# Tablet
only screen and (min-width: 768px)
# Desktop
only screen and (min-width: 992px)
# Huge
only screen and (min-width: 1280px)
Or:
# Phone
only screen and (max-width:320px)
# Tablet
only screen and (min-width:321px) and (max-width:768px)
# Desktop
only screen and (min-width:769px)
每个设备的断点应该是什么?

特别小的设备~手机(< 768px) 小设备~平板电脑(>= 768px) 中型设备~台式机(>= 992px) 大型设备~桌面 (> = 1200 px)

如果你想瞄准一个设备，那么只需要写min-device-width。例如:
为iPhone
@media only screen and (min-device-width: 480px){}
为平板电脑
@media only screen and (min-device-width: 768px){}

对我来说最好的解决方案，检测设备是否移动:
@media (pointer:none), (pointer:coarse) {
}
