CSS @media查询无法正常工作

Question

需要为每个移动设备缩放带有一个图像（徽标）的媒体请求：iPhone 5,6,6 +，iPad以及大屏幕上。 因此，我几乎需要指定宽度等形式的样式。对于纵向和横向方向。 所有中只适用于在iPhone 6，iPad的大屏幕（=> 1600像素） 对于小屏幕（480）和iPhone 6+不起作用（在Chrome中查看）

对于应用为iPhone 6+媒体查询对于iPhone 5 ...

请告诉我，请问我的代码有什么问题？ 我将不胜感激！

@media only screen and (max-width: 320px) and (max-width : 480px) { 
.logo-mobile img { 
    width: 150px; 
    transform: translateY(-7px); 
} 
} 

@media only screen and (min-width: 321px) and (max-width : 480px) {

@media only screen and (min-width: 320px) and (max-height: 568px) and

} 

@media only screen and (min-width: 320px) and (max-height: 568px) and 
(orientation: portrait) and (-webkit-device-pixel-ratio: 2){

    transform: translateY(-7px); 
} 
} 

@media only screen and (min-width: 375px) and (max-height: 667px) and

} 

@media only screen and (min-width: 375px) and (max-height: 667px) and 
(orientation: portrait) and (-webkit-device-pixel-ratio: 2){ 
.logo-mobile img { 
    width: 100%; 
    transform: translateY(-11px); 
} 
} 

@media only screen and (min-width: 414px) and (max-height: 736px) and 
(orientation: landscape) and (-webkit-device-pixel-ratio: 2) { 
.logo-mobile img { 
    width: 144px; 
    transform: translateY(-8px); 
} 
} 

@media only screen and (min-width: 414px) and (max-height: 736px) and

.logo-mobile img { 
    width: 144px; 
    transform: translateY(-8px);

@media only screen and (min-width: 768px) and (max-width: 1024px) and 
(orientation: landscape) and (-webkit-device-pixel-ratio: 2) { 
.logo-mobile img { 
    width: 100%; 
    transform: translateY(-8px); 
} 
} 

@media only screen and (min-width: 768px) and (max-width: 1024px) and 
(orientation: portrait) and (-webkit-device-pixel-ratio: 2) { 
.logo-mobile img {

    transform: translateY(5px); 
} 

@media only screen and (min-width: 1600px) { 
.logo-mobile img {`enter code here` 
    width: 100%; 
} 
}

那么你可以通过确保启动你添加的meta标签

<meta name="viewport" content="width=device-width, initial-scale=1.0" /> 

你也可以考虑加入适量的前缀您CSS3选择器是这样的...

-webkit-transform: translateY(8px)//Chrome 
-o-transform: translateY(8px) //Opera 

等等。您可以检查w3schools以获取css3前缀的完整列表。我希望这可以帮助...
