Võrkkesta kuvav meedia päring - CSS-trikid

Anonim

Suure eraldusvõimega graafika lisamiseks, kuid ainult ekraanide jaoks, mis neid kasutada saavad. „Võrkkest” on „2x”:

@media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi) ( /* Retina-specific stuff here */ )

Või muud kõrglahutusega pildid:

/* 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 */ )

Vana kraam (ära kasuta, säilitades järeltulijate jaoks)

@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 */ )

See on rohkem tulevikukindel ...

@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 */ )

Märkused:

  • Ülim imelik min--moz-device-pixel-ratioon ilmselt viga. Võib-olla soovite seda lisada -moz-min-device-pixel-ratioka juhul, kui nad selle parandavad, kuid jätavad selle eesliidetuks.
  • Siin on lahutusühikute spetsifikatsioon.

Näide:

Oletame, et teil oli kujunduses kolm peamist murdepunkti. Sellel kujundusel oli ka suur taustagraafika ja soovisite, et see oleks parim mis tahes ekraanil (võrkkestal või mitte) ega raiskaks ribalaiust. Oleksite seadnud 6 meediumipäringut, ühe iga katkestuspunkti jaoks ja ühe võrkkestal nende katkestuspunktide jaoks. Siis alistaksite taustpildi lõpuni alla.
