ios - 如何禁用 iOS Mail App 文本放大

Question

我想为我的电子邮件签名使用 ascii 艺术，它在 Gmail、Polymail 和其他一些客户端中工作得很好。唯一的异常(exception)是 iOS 邮件应用程序，它会放大我的 ascii 代码并因此破坏图像。我怎样才能阻止邮件应用程序这样做？

-webkit-text-size-adjust: 100%;

似乎不再起作用(-webkit-text-size-adjust: none; 也不起作用)，如此处所述:How to avoid iOS automatic font size adjustment?

我试图在 iOS 邮件应用程序中正确显示的签名:

Answer 1

不幸的是，-webkit-text-size-adjust: none|100% 仅适用于14px 及以上的字体。我不是建议您更改 ascii 艺术的设计，但可能值得测试更大的字体大小，看看您是否可以成功地取消 iOS 邮件的文本大小调整。
