我有一个基本的例子，应该在移动设备上将这三个表单元格显示为块（在彼此下面）。
然而，这在iPad、iPhone和三星手机上似乎都不起作用。它在模拟移动显示的常规浏览器和网站上运行（可能用于网页），但在移动设备的实际邮件客户端上查看时，display: block属性似乎被忽略了。
有什么东西不见了吗？或者，如果根本不支持display-属性，还有什么选择？
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<meta charset="utf-8">
<title>Mobilize me</title>
<style type="text/css">
@media only screen and (max-width: 1400px) {
table,tr,td{

display: block !important;

}
}
</style>
</head>
<body>
<table cellspacing="0" cellpadding="0" width="900">

<td width="33%" bgcolor="green">

<td width="33%" bgcolor="blue">

</table>

</html>
值得注意的是，这个线程中的示例也不起作用。
使用三个带有"align="的嵌套表来复制"float"，并使用媒体查询将表的大小调整为100%，在移动设备上显示：块。
我添加了类来区分容器表和块表。还添加了一些内联样式以提供帮助。
例如
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html>
<head>
<meta charset="utf-8">
<title>Mobilize me</title>
<style type="text/css">
@media only screen and (max-width: 900px) {
.container {
width: 100% !important;
text-align:center !important;
}
.blocktable {
width: 100% !important;
display: block !important;
margin: 0 auto !important;
}
}
</style>
</head>
<body>
<table cellspacing="0" cellpadding="0" border="0" width="900" class="container" style="border-collapse:collapse;">
<tr>
<td align="center">
<table align="left" bgcolor="RED" cellspacing="0" cellpadding="0" border="0" width="33%" class="blocktable" style="border-collapse:collapse;">
<tr>
<td>one</td>
</tr>
</table>
<table align="left" bgcolor="GREEN" cellspacing="0" cellpadding="0" border="0" width="34%" class="blocktable" style="border-collapse:collapse;">
<tr>
<td>two</td>
</tr>
</table>
<table align="right" bgcolor="BLUE" cellspacing="0" cellpadding="0" border="0" width="33%" class="blocktable" style="border-collapse:collapse;">
<tr>
<td>three</td>
</tr>
</table>
</td>
</tr>
</table>

在撰写本文时，我认为可以肯定地得出结论，即这种技术不受支持。
一种更好的方法是使用两种不同的显示器：一种用于桌面阅读器，另一种用于移动阅读器，如下所示（经过测试并有效）：
