3媒体查询iphone肖像，风景和ipad肖像 [英] 3 media queries for iphone portrait, landscape and ipad portrait

问题描述

我尝试过 width & device-width 但是在横向的iPhone上，这个代码从来不会变成背景红色;

I have tried the different combinations of width & device-width but on the iPhone in landscape this code never turns the background red;

我有超过1个媒体查询。请参阅此 JSfiddle示例 div背景永远不是绿色的，除非您删除最后一个媒体查询

I am having problem when I have more than 1 media query. See this JSfiddle example the div background is never green unless you remove the last media query

这是我想要3个不同的媒体查询，目标是：

This is what I would like 3 different media queries which target:

1. 智能手机和平板电脑（仅限纵向）。这将是我有所有我的通用样式的响应布局


2. width：320px - 479px - 这将适用于小屏幕，如只在纵向的iphone


3. width：480px - 640px - 这将适用于较大的屏幕，如横向中的iphone和纵向中的ipad。不ipad在景观。

注意这是HTML电子邮件，因此无法使用JS。

Note this is for a HTML email so its not possible to use JS.

@media only screen and (max-width: 640px) {
    body { padding: 10px !important }
}
/* Small screen */
@media only screen and (min-device-width: 320px) and (max-device-width: 479px) {
    body { background: blue !important }
}
/* iPhone landscape and iPad portrait */
@media only screen and (max-device-width: 480px) and (max-device-width: 640px) {
    body { 
       background: red !important 
       -webkit-text-size-adjust:none; 
    }
}

推荐答案

您自己尝试修改

@media only screen and (max-width: 640px) and (orientation: portrait) {
    body { padding: 10px !important }
}

/* Small screen */
@media only screen and (min-device-width: 320px) and (max-device-width: 479px) and (orientation: portrait) {
    body { background: blue !important }
}

/* iPhone landscape and iPad portrait */
@media only screen and (max-device-width: 480px) and (orientation: landscape),
@media only screen and (max-device-width: 640px) and (orientation: portrait)  {
    body { 
       background: red !important 
       -webkit-text-size-adjust:none; 
    }
}
