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?

这不仅仅是关于分辨率，你还需要找到设备的DPR: whatismyscreenresolution “设备像素比(DPR)是设备制造商提供的一个数字，用于HiDPI(每英寸高点数)或Retina(苹果的商标)显示器。”
媒体查询示例:(最小分辨率:3.0dppx)

Twitter Bootstrap推荐的最佳断点
/* Custom, iPhone Retina */
@media only screen and (min-width : 320px) {
}
/* Extra Small Devices, Phones */
@media only screen and (min-width : 480px) {
}
/* Small Devices, Tablets */
@media only screen and (min-width : 768px) {
}
/* Medium Devices, Desktops */
@media only screen and (min-width : 992px) {
}
/* Large Devices, Wide Screens */
@media only screen and (min-width : 1200px) {
}

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