我发现这个相关问题有一个很好的解决方案，其中有一个两列设计在达到 320 像素的阈值时堆叠。这很棒;但是，我很好奇是否有一种方法可以使用宽度属性来复制两列堆叠的这种行为，但不是将宽度限制为 320px，而是在彼此堆叠后它们变为宽度 100%。问题可以在这里找到:How to make html email responsive in gmail?

我建议对其进行测试，看看我指的是什么。任何建议将不胜感激，谢谢!
最佳答案
我相信这就是您要找的。您可以使用媒体查询来定位具有类的特定 HTML 元素。我给出了 FullWidth 类，当屏幕尺寸达到 480 像素时， block 将是屏幕的全宽。
一些注意事项:
- 此代码将适用于最新的 Gmail 应用、iOS(通用电子邮件客户端)和 Android 4.4 及以下版本(通用电子邮件客户端)。
- 将媒体查询移到 HTML 的头部。
@media only screen and (max-width:480px) {
.FullWidth{width:100% !important;max-width:100% !important;}
