如何制定仅适用于平板电脑和手机（不适用于台式机）的CSS规则？ 如果我使用：
@media screen and (max-width: 1400px)
“屏幕”是指“浏览器窗口”，而不是“设备屏幕”。因此，如果我在桌面上缩小浏览器窗口，则会应用此CSS规则。
我发现 @media手持设备已过时。
@media screen and (max-device-width: 1400px)
可以正常工作，但是 device-width 似乎也已被弃用

/*
##Device = Desktops
##Screen = 1281px to higher resolution desktops
*/
@media (min-width: 1281px) {
//CSS
}
/*
##Device = Laptops, Desktops
##Screen = B/w 1025px to 1280px
*/
@media (min-width: 1025px) and (max-width: 1280px) {
//CSS
}
/*
##Device = Tablets, Ipads (portrait)
##Screen = B/w 768px to 1024px
*/
@media (min-width: 768px) and (max-width: 1024px) {
//CSS
}
/*
##Device = Tablets, Ipads (landscape)
##Screen = B/w 768px to 1024px
*/
@media (min-width: 768px) and (max-width: 1024px) and (orientation: landscape) {
//CSS
}
/*
##Device = Low Resolution Tablets, Mobiles (Landscape)
##Screen = B/w 481px to 767px
*/
@media (min-width: 481px) and (max-width: 767px) {
//CSS
}
/*
##Device = Most of the Smartphones Mobiles (Portrait)
##Screen = B/w 320px to 479px
*/
@media (min-width: 320px) and (max-width: 480px) {
//CSS
}
