我正在为客户整理电子邮件简报，并发现或多或少的每个电子邮件客户端和应用都提供了或多或少的可读体验（他们仍需要一些工作） - Gmail应用除外。到达断点后，它应显示为一列。但事实并非如此。
我不确定为什么会这样。有没有办法强制应用程序在桌面模式下显示简报，缩小到适合屏幕宽度？或者有没有办法使用条件定位Gmail，以便内容将遵循媒体查询？
相关：我跑过的石蕊试验看起来并不像我在iPhone上得到的结果。那是为什么？

这是我的文件头：

然后这就在我体内：

答案 0 :(得分：1)
Gmail应用和Gmail网络服务会从您的样式标记中删除所有类和ID样式。 More Info Here
Gmail网络服务中有一些基本样式选项，如上面的链接所示，但除此之外，您需要内联所有内容。这会消除响应式设计的功能，因为您无法内联媒体查询。
您最好的选择是流畅的设计（基于小屏幕或大屏幕的百分比）或mobile first hybrid design基本上是为Gmail / Outlook设计的，然后使用媒体查询和样式标签使其适用于所有其他电子邮件客户端。
