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?

这只适用于那些还没有对网站进行“移动优先”设计，并正在寻找一个快速临时解决方案的人。
适用于流动电话
@media (max-width:480px){}
为平板电脑
@media (max-width:960px){}
为什么-桌面
@media (min-width:1025px){}
对于高分辨率笔记本电脑
@media (max-width:1280px){}
现在最常见的是视网膜屏幕设备，换句话说:设备具有高分辨率和非常高的像素密度(但通常小于6英寸物理尺寸)。这就是为什么你需要在CSS上使用视网膜显示专门的媒体查询。这是我能找到的最完整的例子:
@media only screen and (min-width: 320px) {
/* Small screen, non-retina */
}
@media
only screen and (-webkit-min-device-pixel-ratio: 2) and (min-width: 320px),
only screen and ( min--moz-device-pixel-ratio: 2) and (min-width: 320px),
only screen and ( -o-min-device-pixel-ratio: 2/1) and (min-width: 320px),
only screen and ( min-device-pixel-ratio: 2) and (min-width: 320px),
only screen and ( min-resolution: 192dpi) and (min-width: 320px),
only screen and ( min-resolution: 2dppx) and (min-width: 320px) {
/* Small screen, retina, stuff to override above media query */
}
@media only screen and (min-width: 700px) {
/* Medium screen, non-retina */
}
@media
only screen and (-webkit-min-device-pixel-ratio: 2) and (min-width: 700px),
only screen and ( min--moz-device-pixel-ratio: 2) and (min-width: 700px),
only screen and ( -o-min-device-pixel-ratio: 2/1) and (min-width: 700px),
only screen and ( min-device-pixel-ratio: 2) and (min-width: 700px),
only screen and ( min-resolution: 192dpi) and (min-width: 700px),
only screen and ( min-resolution: 2dppx) and (min-width: 700px) {
/* Medium screen, retina, stuff to override above media query */
}
@media only screen and (min-width: 1300px) {
/* Large screen, non-retina */
}
@media
only screen and (-webkit-min-device-pixel-ratio: 2) and (min-width: 1300px),
only screen and ( min--moz-device-pixel-ratio: 2) and (min-width: 1300px),
only screen and ( -o-min-device-pixel-ratio: 2/1) and (min-width: 1300px),
only screen and ( min-device-pixel-ratio: 2) and (min-width: 1300px),
only screen and ( min-resolution: 192dpi) and (min-width: 1300px),
only screen and ( min-resolution: 2dppx) and (min-width: 1300px) {

你也可以为小于320px的场景添加一个，比如Galaxy fold
