Untuk menyertakan grafik beresolusi tinggi, tetapi hanya untuk skrin yang dapat menggunakannya. "Retina" menjadi "2x":
@media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi) ( /* Retina-specific stuff here */ )Atau lain-lain:
/* 1.25 dpr */ @media (-webkit-min-device-pixel-ratio: 1.25), (min-resolution: 120dpi)( /* Retina-specific stuff here */ ) /* 1.3 dpr */ @media (-webkit-min-device-pixel-ratio: 1.3), (min-resolution: 124.8dpi)( /* Retina-specific stuff here */ ) /* 1.5 dpr */ @media (-webkit-min-device-pixel-ratio: 1.5), (min-resolution: 144dpi)( /* Retina-specific stuff here */ )Barang Lama (jangan gunakan, jaga anak cucu)
@media only screen and (-webkit-min-device-pixel-ratio: 2), only screen and ( min--moz-device-pixel-ratio: 2), only screen and ( -o-min-device-pixel-ratio: 2/1) ( /* Retina-specific stuff here */ )Ini lebih banyak bukti masa depan ...
@media only screen and (-webkit-min-device-pixel-ratio: 2), only screen and ( min--moz-device-pixel-ratio: 2), only screen and ( -o-min-device-pixel-ratio: 2/1), only screen and ( min-device-pixel-ratio: 2), only screen and ( min-resolution: 192dpi), only screen and ( min-resolution: 2dppx) ( /* Retina-specific stuff here */ )Catatan:
- Yang peliknya
min--moz-device-pixel-ratiomungkin bug, mungkin ingin dimasukkan-moz-min-device-pixel-ratiojuga sekiranya mereka memperbaikinya tetapi membiarkannya di awalan. - Inilah spesifikasi pada unit resolusi.
Contoh:
Katakan anda mempunyai tiga titik perubahan utama dalam reka bentuk. Reka bentuk ini juga mempunyai grafik latar belakang yang besar dan anda mahukan ia kelihatan terbaik di mana-mana skrin (retina atau tidak) dan tidak membuang lebar jalur apa pun. Anda akan menyediakan 6 pertanyaan media, satu untuk setiap titik putus dan satu untuk setiap titik putus di retina. Kemudian anda akan menukar gambar latar hingga ke bawah.
@media only screen and (min-width: 320px) ( /* Small screen, non-retina */ ) @media only screen and (-webkit-min-device-pixel-ratio: 2) and (min-width: 320px), only screen and ( min--moz-device-pixel-ratio: 2) and (min-width: 320px), only screen and ( -o-min-device-pixel-ratio: 2/1) and (min-width: 320px), only screen and ( min-device-pixel-ratio: 2) and (min-width: 320px), only screen and ( min-resolution: 192dpi) and (min-width: 320px), only screen and ( min-resolution: 2dppx) and (min-width: 320px) ( /* Small screen, retina, stuff to override above media query */ ) @media only screen and (min-width: 700px) ( /* Medium screen, non-retina */ ) @media only screen and (-webkit-min-device-pixel-ratio: 2) and (min-width: 700px), only screen and ( min--moz-device-pixel-ratio: 2) and (min-width: 700px), only screen and ( -o-min-device-pixel-ratio: 2/1) and (min-width: 700px), only screen and ( min-device-pixel-ratio: 2) and (min-width: 700px), only screen and ( min-resolution: 192dpi) and (min-width: 700px), only screen and ( min-resolution: 2dppx) and (min-width: 700px) ( /* Medium screen, retina, stuff to override above media query */ ) @media only screen and (min-width: 1300px) ( /* Large screen, non-retina */ ) @media only screen and (-webkit-min-device-pixel-ratio: 2) and (min-width: 1300px), only screen and ( min--moz-device-pixel-ratio: 2) and (min-width: 1300px), only screen and ( -o-min-device-pixel-ratio: 2/1) and (min-width: 1300px), only screen and ( min-device-pixel-ratio: 2) and (min-width: 1300px), only screen and ( min-resolution: 192dpi) and (min-width: 1300px), only screen and ( min-resolution: 2dppx) and (min-width: 1300px) ( /* Large screen, retina, stuff to override above media query */ )
