For å inkludere høyoppløselig grafikk, men bare for skjermer som kan bruke dem. “Retina” er “2x”:
@media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi) ( /* Retina-specific stuff here */ )Eller andre høyoppløselige oppløsninger:
/* 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 */ )Gamle ting (ikke bruk, hold for ettertiden)
@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 */ )Dette er mer fremtidssikkert ...
@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 */ )Merknader:
- Det super rare
min--moz-device-pixel-ratioer sannsynligvis en feil, vil kanskje også sette-moz-min-device-pixel-ratioinn hvis de fikser det, men lar det stå foran. - Her er spesifikasjonen for oppløsningsenheter.
Eksempel:
La oss si at du hadde tre hovedbruddpunkter i et design. Dette designet hadde også en stor bakgrunnsgrafikk, og du ville at det skulle se best ut på hvilken som helst skjerm (netthinne eller ikke) og ikke kaste bort båndbredde. Du hadde satt opp 6 mediespørsmål, ett for hvert brytpunkt og ett for hvert av disse brytpunktene på netthinnen. Så vil du overstyre bakgrunnsbildet helt ned.
