是否有一些使用媒体查询的新标准。或者我应该说，应该做出一些新的考虑。
CSS 技巧文章似乎效果不佳，因为“智能手机领域”似乎劫持了一切。
我直接使用的代码（除了打印屏幕应该是什么：
/* Smartphones (portrait and landscape) ----------- */
@media only screen
and (min-device-width : 320px)
and (max-device-width : 480px) {
.size:after{ content: "smartphone portrait and landscape";}
body{background-color:#111; color:#fff;}
}
/* Smartphones (landscape) ----------- */
@media only screen
and (min-width : 321px) {
.size:after{ content: "smartphone landscape";}
body{background-color:#222; color:#fff;}
}
/* Smartphones (portrait) ----------- */
@media only screen
and (max-width : 320px) {
.size:after{ content: "smartphones portrait";}
body{background-color:#333; color:#fff;}
}
/* iPads (portrait and landscape) ----------- */
@media only screen
and (min-device-width : 768px)
and (max-device-width : 1024px) {
.size:after{ content: "ipad protrait and landscape";}
body{background-color:#444; color:#fff;}
}
/* iPads (landscape) ----------- */
@media only screen
and (min-device-width : 768px)
and (max-device-width : 1024px)
and (orientation : landscape) {
.size:after{ content: "ipad landscape";}
body{background-color:#555; color:#fff;}
}
/* iPads (portrait) ----------- */
@media only screen
and (min-device-width : 768px)
and (max-device-width : 1024px)
and (orientation : portrait) {
.size:after{ content: "iPads portrait";}
body{background-color:#666; color:#000;}
}
/* Desktops and laptops ----------- */
@media only screen
and (min-width : 1224px) {
.size:after{ content: "desktops and laptops";}
body{background-color:#777; color:#000;}
}
/* Large screens ----------- */
@media only screen
and (min-width : 1824px) {
.size:after{ content: "largscreens";}
body{background-color:#888; color:#000;}
}
/* iPhone 4 ----------- */
@media
only screen and (-webkit-min-device-pixel-ratio : 1.5),
only screen and (min-device-pixel-ratio : 1.5) {
.size:after{ content: "iPhone 4";}
body{background-color:#999; color:#000;}
}

谢谢！
