Question

如何用sass断点实现这个媒体查询？ ...

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

我已经试过这一点，但它会影响桌面版以及...

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

}

这是如何实现你想要的断点青菜什么（断点，上海社会科学院亭子包）。 我试过它在铬（并与网页开发工具模拟设备），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; 
    } 
} 

如果断点看起来太复杂了，您可以使用自己的代码实现此目的。 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; 
    } 
}
