我正在开发一个HTML电子邮件，该电子邮件利用两列用于桌面设计，另一列用于移动设计。与其处理针对桌面版本的特定元素的所有复杂性，并试图使它们适用于移动设备（这样做是带有电子邮件的噩梦。并使桌面版本消失（显示：无），在450px以下的断点。
现在，这有效；但是，在台式机上（450px以上），我将移动台设置为（显示无；显示：无！重要;）存在问题。在大于450px的屏幕尺寸上打开电子邮件（在Gmail，而不是在浏览器中。但是，没有图像存在。Gmail询问"在下面显示图像"，然后单击此重写我的样式表，即使我明确地告诉它也不明确地告诉手机表也出现了。
我知道这是一项棘手的业务，而且我已经尝试了许多解决方法来克服它，但是没有一个奏效。如果有人能帮助我完成这项工作，我将非常感谢。
我的代码如下：

尝试将MSO-RULE添加到您的隐藏中。您也可以使用基本的断点，但是我发现使用@media screen and (max-width:XXpx)也是一个更好的解决方案，因为大多数人不会随身携带小于450像素的笔记本电脑。
电子邮件设计和开发纯粹是一个完全混合的包，祝您好运。
总的来说，我不会采取这种方法来隐藏和不遵守内容。Outlook将完全忽略它，Gmail将做（您知道）不可预测的事情。
这是指我制作的基本模板的链接，可能会有所帮助。
