为什么我的 font-sizes 被 Outlook 2007、10、13、16、19 更改了?

Why are my font-sizes changed by Outlook 2007, 10, 13, 16, 19?

我已经尝试了很多修复程序来启用 Outlook 2007+ (07,10,13,16,19) 来呈现我构建的电子邮件。

我已尝试重置文档和表格。我尝试了很多不同的容器,例如 span、font、p & td's 来包含文本,所有容器都指定了 font-size 和 line-height。放入元标记,更改 html 标记。然而,它只是被忽略了,电子邮件中的所有文本都显示在 font-size: 16px.

是否有明确的方法来保证我的字体显示的大小与我将它们编码为在 Outlook 07+ 版本中的大小相同?

这是我的代码:

结果如下:

如果您参考这张图片,您会看到大标题在 outlook 2007+ 版本中显示的尺寸要小得多。

编辑: 解决方案 结果是,确保我使用 [=60= 在头部应用样式] 以及通过定位属性(一些引擎必须忽略元素的定位)。除了删除 !important.

的所有 inline-style 用途外

这是供您查看的更新代码段:

非常感谢贡献者,为我省去了很多麻烦! <3

删除您添加的所有内联 !important 语句。这导致了 Outlook 中的问题。
不知道为什么(可能是内联 !important 语句无效)但在对象初始状态下不需要它们。
!important 只应在头部使用以覆盖对象的初始状态。

我也会从你头脑中的属性选择器转移开来 CSS。它已经过时,可能不再适用于任何地方。我会简单地将它们转换为一般 class 声明。
即:table[class=full-width] 变为 .full-width
