如何用sass斷點實現橫向和像素口徑媒體查詢

Question

如何用sass斷點實現這個媒體查詢？ ...

@media only screen 
    and (min-device-width: 375px) 
    and (max-device-width: 667px) 
    and (-webkit-min-device-pixel-ratio: 2) 
    and (orientation: landscape) 

我已經試過這一點，但它會影響桌面版以及...

$mobileLandscape: screen and (min-device-width: 375px) and (max-device-width: 667px) and (-webkit-min-device-pixel-ratio: 2) and (orientation: landscape); 

@include breakpoint($mobileLandscape) { 
}

這是如何實現你想要的斷點青菜什麼（斷點，上海社會科學院亭子包）。 我試過它在鉻（並與網頁開發工具模擬設備），它的工作原理。

// With third-party tool 
// Breakpoint https://github.com/at-import/breakpoint 
// You can find installation instructions here https://github.com/at-import/breakpoint/wiki/Installation 
$mobile-landscape-breakpoint: 'only screen' 375px 667px, (-webkit-min-device-pixel-ratio 2), (orientation landscape); 

body { 
    @include breakpoint($mobile-landscape-breakpoint) { 
     color: blue; 
    } 
} 

如果斷點看起來太複雜了，您可以使用自己的代碼實現此目的。 例如：

// With Variable 
$mobileLandscape: "only screen and (min-device-width: 375px) and (max-device-width: 667px) and (-webkit-min-device-pixel-ratio: 2) and (orientation: landscape)"; 

@media #{$mobileLandscape} { 
    body { 
     color: red; 
    } 
} 

// With Mixin 
@mixin mq($breakpoint){ 
    @if $breakpoint == "mobile-landscape"{ 
     @media only screen and (min-device-width: 375px) and (max-device-width: 667px) and (-webkit-min-device-pixel-ratio: 2) and (orientation: landscape){ 
      @content; 
     } 
    } 
} 

body{ 
    @include mq("mobile-landscape"){ 
     color: green; 
    } 
}
