那么以后大家在iPhone4和iPad设备上，就可以按照横竖板来定样式了：
1、iPhone4竖板
@media
only screen and (-webkit-min-device-pixel-ratio : 1.5) and (orientation:portrait),
only screen and (min-device-pixel-ratio : 1.5) and (orientation:portrait){
/*你的样式写在这里*/
}
2、iPhone横板
@media
only screen and (-webkit-min-device-pixel-ratio : 1.5) and (orientation:landscape),
only screen and (min-device-pixel-ratio : 1.5) and (orientation:landscape){
/*你的样式写在这里*/
}
3、iPad竖板
@media screen and (max-device-width: 768px) and (orientation: portrait) {
/*你的样式写在这里*/
}
4、iPad横板
@media screen and (max-device-width: 1024px) and (orientation: landscape) {
/*你样式写在这里*/
}
