html - Bootstrap : how to make left and right containers with same height?

<分区>

代码:

#left {
  background-color: rgba(255,0,0,0.3);
}

#right {
  background-color: rgba(0,255,0,0.3);
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<head>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
</head>

<body>
<div class="col-xs-3" id="left">
<p>short</p>
</div>
<div class="col-xs-3" id="right">
<p>long</p><p>long</p><p>long</p><p>long</p><p>long</p>
</div>
</body>

如您所见，左侧容器和右侧容器具有不同的高度。谁能给我一些关于制作相同高度的建议吗？

最佳答案

通过简单地声明 display: flex在包装 parent 身上将起作用。这意味着您必须将列包装在新的 <div> 中。，例如:

<div class="row row-equal-height">

  <div class="col-xs-3" id="left">
    <p>short</p>
  </div>
  <div class="col-xs-3" id="right">
    <p>long</p>
    <p>long</p>
    <p>long</p>
    <p>long</p>
    <p>long</p>
  </div>

</div>

对于您的 CSS，您可以这样做:

.row-equal-height {
    display: flex;
}

但是，这意味着您将不得不依赖 browser support for CSS3 flexbox specification .好消息是，凭借供应商前缀，它今天得到了非常广泛的支持 (>97%)。

请参阅下面的概念验证:

#left {
  background-color: red;
}

#right {
  background-color: green;
}

.row-equal-height {
  display: flex;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

</head>

<body>
  <div class="row row-equal-height">
    <div class="col-xs-3" id="left">
      <p>short</p>
    </div>
    <div class="col-xs-3" id="right">
      <p>long</p>
      <p>long</p>
      <p>long</p>
      <p>long</p>
      <p>long</p>
    </div>
  </div>
</body>

最后的解决方案:`display: table`

您应该将此视为最后一搏的解决方案，因为众所周知，您不应该将表格用于布局目的。然而，如果你想支持根本不支持 flexbox 的浏览器(提示 IE9 及以下)，这可能是你唯一的出路:

#left {
  background-color: red;
}

#right {
  background-color: green;
}

.wrapper {
  display: table;
  border-collapse: collapse;
  width: 50%;
}

.row {
  display: table-row;
}

.row > div {
  display: table-cell;
  float: none;
  width: 50%;
}

<body>
  <div class="wrapper">
    <div class="row">
      <div class="col-xs-3" id="left">
        <p>short</p>
      </div>
      <div class="col-xs-3" id="right">
        <p>long</p>
        <p>long</p>
        <p>long</p>
        <p>long</p>
        <p>long</p>
      </div>
    </div>
  </div>
</body>
