布局:一列根据需要宽，另一列占用剩余空间

Question

我需要两列布局，就像表格一样，我不知道列有多宽。

我需要右列与其内容一样宽（无自动换行），左列占用剩余空间，如果没有可用空间，则进行自动换行。

右列没问题，而左div mainInfos如果内容需要，它会放在它上面。

我希望列并排放置。我该怎么做才能达到这个结果？

容器具有固定宽度。我不想使用jquery。

#post {
	overflow: hidden;
	width: 400px;
	border: solid 1px;
}
#post .mainInfos {
	overflow: hidden;
}
#post .details {
	float: right;
}

<div id="post">
	<div class="mainInfos">really really long content that should be wrapped and should be all at the left of "small content", on the same line</div>
	<div class="details">small content</div>
</div>

Answer 1

适用于新旧浏览器的 flexbox 的一种替代方法是在内部div 上使用 display:table-cell：

#post {
  overflow: hidden;
  width: 400px;
  border: solid 1px;
}
#post > div {
  display: table-cell;
}
#post .details {
  white-space: nowrap;
}

<div id="post">
  <div class="mainInfos">really really long content that should be wrapped and should be all at the left of "small content", on the same line</div>
  <div class="details">small content</div>
</div>

Answer 2

你可以为此使用弹性框：

1. 将display: flex添加到容器post

2. 将white-space: nowrap添加到details以防止其换行

3. 将flex: 1添加到mainInfos，使其占用剩余空间。

请参阅下面的演示：

#post {
  display: flex;
  width: 400px;
  border: solid 1px;
}
#post .mainInfos {
  flex: 1;
}
#post .details {
  white-space: nowrap;
}

<div id="post">
  <div class="mainInfos">really really long content that should be wrapped and should be all at the left of "small content", on the same line</div>
  <div class="details">small content</div>
</div>

Answer 3

使用 Flexbox，首先删除右列上的浮点数：。添加到父元素 （#post） 这个，

display: flex

  -moz-box-align: center;
  -ms-flex-align: center;
  align-items: center;
  display: -webkit-box;
  display: -webkit-flex;
  display: -moz-box;
  display: -ms-flexbox;
  display: flex;
  -webkit-box-flex: 0;
  -webkit-flex: 0 0 400px;
  -moz-box-flex: 0;
  -ms-flex: 0 0 400px;
  flex: 0 0 400px;

  border: solid 1px;
  margin-left: auto;
  margin-right: auto;
  margin-top: 50px;
