我找到了一个对我来说似乎完美的解决方案，但它需要额外的<div>标记。 事实证明，没有必要使用<table>标记来像在表中那样对齐，使用display:table-row;和显示:表格单元;风格:

<style type="text/css">
dl > div {
  display: table-row;
}
dl > div > dt {
  display: table-cell;
  background: #ff0;
}
dl > div > dd {
  display: table-cell;
  padding-left: 1em;
  background: #0ff;
}
</style>

<dl>
  <div>
    <dt>Mercury</dt>
    <dd>Mercury (0.4 AU from the Sun) is the closest planet to the Sun and the smallest planet.</dd>
  </div>
  <div>
    <dt>Venus</dt>
    <dd>Venus (0.7 AU) is close in size to Earth, (0.815 Earth masses) and like Earth, has a thick silicate mantle around an iron core.</dd>
  </div>
  <div>
    <dt>Earth</dt>
    <dd>Earth (1 AU) is the largest and densest of the inner planets, the only one known to have current geological activity.</dd>
  </div>
</dl>

CSS网格布局

与表一样，网格布局允许作者将元素对齐为列和行。 https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Grid_Layout

要更改列大小，请查看grid-template-columns属性。

dl { display: grid; grid-template-columns: max-content auto; } dt { grid-column-start: 1; } dd { grid-column-start: 2; } <dl> <dt>Mercury</dt> <dd>Mercury (0.4 AU from the Sun) is the closest planet to the Sun and the smallest planet.</dd> <dt>Venus</dt> <dd>Venus (0.7 AU) is close in size to Earth, (0.815 Earth masses) and like Earth, has a thick silicate mantle around an iron core.</dd> <dt>Earth</dt> <dd>Earth (1 AU) is the largest and densest of the inner planets, the only one known to have current geological activity.</dd> </dl>

因为我还没有看到一个适用于我的用例的示例，所以这里是我能够实现的最完整的解决方案。

dd { margin: 0; } dd::after { content: '\A'; white-space: pre-line; } dd:last-of-type::after { content: ''; } dd, dt { display: inline; } dd, dt, .address { vertical-align: middle; } dt { font-weight: bolder; } dt::after { content: ': '; } .address { display: inline-block; white-space: pre; } Surrounding <dl> <dt>Phone Number</dt> <dd>+1 (800) 555-1234</dd> <dt>Email Address</dt> <dd><a href="#">example@example.com</a></dd> <dt>Postal Address</dt> <dd><div class="address">123 FAKE ST<br />EXAMPLE EX 00000</div></dd> </dl> Text

奇怪的是，它对display: inline-block不起作用。我想如果你需要设置任何dt元素或dd元素的大小，你可以将dl的显示设置为display: flexbox;显示:-webkit-flex;显示:flex;dd元素和dt元素的flex简写类似flex: 1.1 50% display为display: inline-block。但我还没有对此进行测试，所以请谨慎处理。

下面是另一个选项，通过内联显示dt和dd，然后在dd后面添加换行符。

dt, dd {
 display: inline;
}
dd:after {
 content:"\a";
 white-space: pre;
}

这类似于上面Navaneeth的解决方案，但是使用这种方法，内容不会像在表中那样排列，但是无论长度如何，dd将立即在每一行上跟随dt。

dl { width: 100%; overflow: hidden; background: #ff0; padding: 0; margin: 0 } dt { float: left; width: 50%; /* adjust the width; make sure the total of both is 100% */ background: #cc0; padding: 0; margin: 0 } dd { float: left; width: 50%; /* adjust the width; make sure the total of both is 100% */ background: #dd0; padding: 0; margin: 0 } <dl> <dt>Mercury</dt> <dd>Mercury (0.4 AU from the Sun) is the closest planet to the Sun and the smallest planet.</dd> <dt>Venus</dt> <dd>Venus (0.7 AU) is close in size to Earth, (0.815 Earth masses) and like Earth, has a thick silicate mantle around an iron core.</dd> <dt>Earth</dt> <dd>Earth (1 AU) is the largest and densest of the inner planets, the only one known to have current geological activity.</dd> </dl>

这里的大多数建议都是可行的，但是您应该只将通用代码放入样式表中，并将特定代码放入如下所示的html代码中。否则，您将最终得到一个臃肿的样式表。

我是这样做的:

你的样式表代码:

<style>
    dt {
        float:left;
    }
    dd {
        border-left:2px dotted #aaa;
        padding-left: 1em;
        margin: .5em;
    }   
</style>

你的html代码:

<dl>
    <dt>1st Entity</dt>
    <dd style="margin-left: 5em;">Consumer</dd>
    <dt>2nd Entity</dt>
    <dd style="margin-left: 5em;">Merchant</dd>
    <dt>3rd Entity</dt>
    <dd style="margin-left: 5em;">Provider, or cToken direct to Merchant</dd>
    <dt>4th Entity</dt>
    <dd style="margin-left: 5em;">cToken to Provider</dd>
</dl>

是这样的
