iOS 10 封邮件 HTML 未正确响应

Question

我正在创建时事通讯，我发现了奇怪的行为。

我有一个 table，里面有 2 个，我希望它们是一个块，宽度为 100%，但会发生以下情况：

它还会破坏邮件的其他部分。我已经尝试了很多...每个视口，max-width，min-width，我不知道该怎么做...

我已验证，媒体查询正常

我需要一些特殊技巧吗？

当前问题：

iOS 10 不接受 "display: block;" "td" 标签

Answer 1

尝试对 table 和 table td 使用 [class="classname"]。

table[class="mblock"],
table td[class="mblock"]  {
    width: 100% !important;
    display: block !important;
}

事实上，只要定位 td;

，这也同样有效

td[class="mblock"] {
    width: 100% !important;
    display: block !important;
}

媒体查询的替代方法

我假设对页眉中的原始样式进行了某种转换（例如 MS Word ML）。

一种对几乎（如果不是）所有人都相当防弹的替代方法称为 Fab Four Technique 它不依赖于媒体查询，这意味着您可以不支持它的客户端中的自适应布局；如;展望和 Gmail。

Answer 2

我无法准确判断您的问题出在哪里，但可以看到上面提供的代码中有很多重复项。可能存在冲突、特异性问题，或者 iOS 邮件变得混乱并排除了重要的 CSS 规则。

这是一个 600 像素宽的电子邮件的简化示例，其中有两个偶数列堆叠。我没有包括 CSS 中的 most（与此问题无关）和周围的大部分 HTML。我最后还删除了孤立的。

CSS进入<head>:

<style>
    @media screen and (max-width: 600px) {
        .mblock {
            display: block !important;
            width: 100% !important;
            max-width: 100% !important;
            direction: ltr !important;
        }
    }
</style>

和HTML：

<!-- // Begin Template teasertype2 \ -->
<table role="presentation" cellspacing="0" cellpadding="0" border="0" align="center" width="100%" style="max-width: 600px;">
    <tr>
        <td bgcolor="#ffffff" align="center" height="100%" valign="top" width="100%">
            <!--[if mso]>
            <table role="presentation" border="0" cellspacing="0" cellpadding="0" align="center" width="600">
            <tr>
            <td align="center" valign="top" width="600">
            <![endif]-->
            <table role="presentation" border="0" cellpadding="0" cellspacing="0" align="center" width="100%" style="max-width:600px;">
                <tr>
                    <td align="center" valign="top" style="font-size:0;">
                        <!--[if mso]>
                        <table role="presentation" border="0" cellspacing="0" cellpadding="0" align="center" width="100%">
                        <tr>
                        <td align="left" valign="top" width="300">
                        <![endif]-->
                        <div style="display:inline-block; margin: 0 -2px; width:100%; min-width:200px; max-width:300px; vertical-align:top;" class="mblock">
                            <table role="presentation" cellspacing="0" cellpadding="0" border="0" width="100%">
                                <tr>
                                    <td class="txt pretitle" style="font-size: 12px; line-height: 14px; font-weight: bold; box-sizing: border-box; mso-line-height-rule: exactly; color: #000000; font-family: Helvetica, Arial, sans-serif; margin: 0; padding: 0;" mc:edit="pretitle2">
                                        LEFT
                                    </td>
                                </tr>
                            </table>
                        </div>
                        <!--[if mso]>
                        </td>
                        <td align="left" valign="top" width="300">
                        <![endif]-->
                        <div style="display:inline-block; margin: 0 -2px; width:100%; min-width:200px; max-width:300px; vertical-align:top;" class="mblock">
                            <table role="presentation" cellspacing="0" cellpadding="0" border="0" width="100%">
                                <tr>
                                    <td class="txt pretitle" style="font-size: 12px; line-height: 14px; font-weight: bold; box-sizing: border-box; mso-line-height-rule: exactly; color: #000000; font-family: Helvetica, Arial, sans-serif; margin: 0; padding: 0;" mc:edit="pretitle2">
                                        RIGHT
                                    </td>
                                </tr>
                            </table>
                        </div>
                        <!--[if mso]>
                        </td>
                        </tr>
                        </table>
                        <![endif]-->
                    </td>
                </tr>
            </table>
            <!--[if mso]>
            </td>
            </tr>
            </table>
            <![endif]-->
        </td>
    </tr>
</table>
<!-- // End Template teasertype2 \ -->

此技术使用混合方法，它使用最大宽度和最小宽度来施加严格的基线（允许一些移动）并为无论如何都束缚在桌面上的 Outlook 施加固定的宽宽度（因此 <!--[if !mso]> 东西）。媒体查询可以在支持它的客户端中进一步增强电子邮件，例如 iOS Mail.
