我发现这个相关的问题有一个很好的解决方案，其中有两个列设计在达到320px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width属性来复制两列堆叠的这种行为，但是宽度被限制为320px，它们在彼此堆叠后变为宽度100％。问题可以在这里找到：How to make html email responsive in gmail?

我建议测试一下，看看我指的是什么。任何建议都将不胜感激，谢谢！

我相信这就是你要找的东西。您可以使用媒体查询来定位具有类的特定HTML元素。我给了一类FullWidth，当屏幕尺寸达到480像素时，这些块将是屏幕的全宽。
有几点需要注意：
@media only screen and (max-width:480px) {
.FullWidth{width:100% !important;max-width:100% !important;}
