我有一个装有两件​​物品的容器。其中一项是select元素，因此我需要size通过 HTML 设置属性。我希望容器中的其他项目拉伸其高度以适合容器。我想不通。我不想明确设置容器的高度，因为我不知道那个选择框的大小。

.container {
  padding: 5px;
  border: 1px solid black;
}

.container .column {
  display: inline-block;
  width: 40%;
  background-color: #AAA;
  padding: 5px;
  margin: 5px;
  vertical-align: top;
  height: 100%;
}

select {
  width: 100%;
}
<div class="container">
  <div class="column">Stretch to fill?</div>
  <div class="column">
    <select size="15">
            <option>Option 1</option>
            <option>Option 2</option>
        </select>
  </div>
  <div>

如果table-cell是一个选项，这是一种方法：

.container {
  display: table;
  width: 100%;
  padding: 5px;
  border: 1px solid black;
}

.container .column {
  display: table-cell;
  width: 40%;
  background-color: #AAA;
  padding: 5px;
  border: 5px solid white;
  vertical-align: top;
  height: 100%;
}

select {
  width: 100%;
}
<div class="container">
  <div class="column">Stretch to fill?</div>
  <div class="column">
    <select size="15">
            <option>Option 1</option>
            <option>Option 2</option>
        </select>
  </div>
  <div>

如果我明白您在说什么，您将面临100% 高度列的问题。很遗憾地告诉您，除了“黑客”之外，没有实际的解决方案。

在这里，您可以找到其中几个解决方法。我喜欢使用一种真正的布局方法。

顺便说一句，这是在想你不想使用实验性的 css3 列属性。

这里没有答案让我感到安慰，所以我去寻找真相。我添加了更多的 CSS 来说明两个框之间的间距。

CSS：

 .wrapper {
  background-color:gray;
}

.container {
    margin: 25px auto;
    display: inline-flex;
}

.leftbox {
    height: inherit;
    display: inline-block;
    border: 1px solid #D7D2CB;
    background-color: #FFFFFF;
    border-radius: 5px;
    max-width: 550px;
    margin-right: 18px;
    align-items: stretch;
    padding: 15px;
    width: 100%;
}

.rightbox {
    height: 100%;
    display: inline-block;
    border: 1px solid #D7D2CB;
    background-color: #FFFFFF;
    border-radius: 5px;
    align-items: stretch;
    max-width: 300px;
    width: 100%;
    padding: 20px 15px;
}

HTML：

<div class="wrapper">
  <div class="container">
    <div class="leftbox">
      There is something here, I am not avoiding it.
    </div>
    <div class="rightbox">
      Probably something else here but much much much much much much much much much much much much much much much much much much much much much much much much much much much much much bigger.
    </div>
  </div>
</div>

我还需要一个伪元素的示例：
