我正在使用 Python/Flask 和 mandrill smtp 在用户共享时发送电子邮件确认。我遇到了移动字体大小超小的问题。
我的解决方案是这样的：
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta name="x-apple-disable-message-reformatting">
<style type="text/css">
.bodyContent p {font-size: 18px; line-height: 140%;}
footer {font-size: 14px; }
footer img { width: 30px;}
@media (max-width: 480px) {
.bodyContent p {font-size:28px !important;}
.bodyContent .button {font-size: 34px !important; padding: 10px !important;}
footer {font-size: 22px !important; }
footer img { width: 50px !important;}
.headerimg {height: 80px !important;}
h3 {font-size: 32px !important;}
}
</style>
</head>
</html>
身体是：
<body class="bodyContent" style="border-top: 5px solid #248F8D; color: #444; font-weight: 300; font-family: Helvetica, Arial, Tahoma, sans-serif; background-color: white; margin: 0; padding: 0; width: 100%; box-sizing: border-box; line-height: 140%;">
我不确定为什么会发生这种情况，因为对于其他电子邮件，我将其简单化，正文中的标准字体大小为 16 像素或 18 像素，它适用于网络和移动设备。
上述配置适用于 iOS 电子邮件、iMail 和基于 Web 的 Gmail（我还需要测试该应用程序），但感觉有些不对劲。 Helvetica 在移动设备上的 28px 字体大小似乎太大了不是吗？ 我认为这是考虑到视网膜显示，但我不确定这将如何适用于其他移动设备。视口和 x-apple-disable-message-reformatting 似乎没有做任何事情。
如果有帮助，这里是电子邮件的 RAW 标头：
