这是我的视口元数据:

这是我的CSS:
/* ---------- */
/* iPad 3 */
/* ---------- */
@media only screen and (-webkit-min-device-pixel-ratio: 2) and (min-device-width: 1536px) and (max-device-width: 2048px) and (orientation: landscape) {
body { background: red; }
}
@media only screen and (-webkit-min-device-pixel-ratio: 2) and (min-device-width: 1536px) and (max-device-width: 2048px) and (orientation: portrait) {
body { background: orange; }
}
/* ------------ */
/* iPhone 4 */
/* ------------ */
@media only screen and (-webkit-min-device-pixel-ratio: 2) and (min-device-width: 640px) and (max-device-width: 960px) and (orientation: landscape) {
body { background: blue; }
}
@media only screen and (-webkit-min-device-pixel-ratio: 2) and (min-device-width: 640px) and (max-device-width: 960px) and (orientation: portrait) {
body { background: gray; }
}
为什么 iPad3 的 css 会覆盖 iPhone4 的 css?
