如何在没有媒体查询的情况下堆叠3个流体(响应)列

我想编写一个响应流畅的电子邮件模板,我可以在不使用媒体查询的情况下堆叠3列。我可以使用下面的代码使它们浮动,并在宽度小于表的两个最小元素宽度之和时使它们堆叠。但是当宽度大于此值时,只有第三列堆叠,其余两列仍然是内嵌的。

如何在不使用媒体查询的情况下堆叠它们?如果可能的话。



         table {
          }
          tr{
          	background-color: lightblue;
			
              min-width: 160px;
          }
          td{
          	display:block;
              width:33%;
              background-color: green;
              margin-left:auto;
              margin-right: auto;
              text-align: center;
              padding:0px;
              float: left;
              min-width: 160px !important;
              
          }

    <table width="100%" bgcolor="green">
          <tr>
              <center>
              <td>1</td>
              <td>2</td>
              <td>3</td>
              </center>
          </tr>
      	
      </table>

您可以使用混合方法在每个电子邮件客户端中安全地实现此目的,以便为电子邮件客户端重新配置不同屏幕尺寸的布局,而不管媒体查询支持如何。从本质上讲,它使用max-widthmin-width来强加基线(允许某些移动),并为无论如何被束缚到桌面的Outlook强加固定宽度宽度。一旦设置了适合移动设备的基线,媒体查询就可以在支持它的客户端中逐步增强电子邮件,但不需要进行列堆叠。

以下是没有媒体查询的三列堆叠示例:

<html>
<body width="100%" bgcolor="#222222" style="margin: 0; mso-line-height-rule: exactly;">
   <center style="width: 100%; background: #222222; text-align: left;">

  <!--
            Set the email width. Defined in two places:
            1. max-width for all clients except Desktop Windows Outlook, allowing the email to squish on narrow but never go wider than 680px.
            2. MSO tags for Desktop Windows Outlook enforce a 680px width.
            Note: The Fluid and Responsive templates have a different width (600px). The hybrid grid is more "fragile", and I've found that 680px is a good width. Change with caution.
        -->
  <div style="max-width: 680px; margin: auto;">
    <!--[if mso]>
            <table role="presentation" cellspacing="0" cellpadding="0" border="0" width="680" align="center">
            <tr>
            <td>
            <![endif]-->

    <!-- Email Header : BEGIN -->
    <table role="presentation" cellspacing="0" cellpadding="0" border="0" align="center" width="100%" style="max-width: 680px;">

      <!-- 3 Even Columns : BEGIN -->
      <tr>
        <td bgcolor="#ffffff" align="center" height="100%" valign="top" width="100%" style="padding: 10px 0;">
          <!--[if mso]>
                        <table role="presentation" border="0" cellspacing="0" cellpadding="0" align="center" width="660">
                        <tr>
                        <td align="center" valign="top" width="660">
