メディアクエリを使用して、iPhone、iPadの横向きモードと縦向きモードを区別する必要があるプロジェクトに取り組んでいます。また、iPad 3、iPhone4sを使用しています。これは単純でわかりやすいように聞こえるかもしれませんが、私はこれを機能させるのに最も苦労しています。私が最も近いのはこれです：-

@media (min-device-width: 768px)
and (max-device-width: 1024px)
and (orientation: portrait) {
/*iPad portrait*/
}

@media (min-device-width: 768px)
and (max-device-width: 1024px)
and (orientation: landscape) {
/*iPad landscape*/
}

@media (max-device-width: 480px)
and (orientation: portrait) {
/*iPhone portrait*/
}

@media (max-device-width: 480px)
and (orientation: landscape) {
/*iPhone landscape*/
}

ただし、これはiPhoneのポートレートモードとランドスケープモードを区別しません。何が間違っている可能性があるかについての手がかりはありますか？

これは、iPhoneで機能するクエリを示すサンプルコードです。縦向きは白、横向きは黒です。外部ファイルを必要とせずにアイコンを提供するだけだったbase64の部分は無視してかまいません。
