Bootstrap 4中列的高度相等 [英] Equal height of columns in Bootstrap 4

问题描述

我在此设计中有一些非常规的DIV，如下所示.我可以使用高度并做到这一点，但我希望它可以动态变化: 例如，如果DIV的内容更多，并且右侧块中的一个块的高度发生了变化，则左侧DIV也会自动调整其高度.我想知道flex是否可以帮助您.将其更改为以下方法:

I have a little non-conventional DIV in this design as shown below. I could use a height and do it but I want it to change dynamically: For instance, if the DIV has more content and the height changes in one of the block on the right, the left DIV auto adjust it's height as well. I wonder if flex could help. Here's how it should change to:

到目前为止，我有这个HTML:

I have this HTML so far:

<div class="container">
  <div class="row row-eq-height">
      <div class="col-sm-8 col-8">
        <div class="black">
          <p>Bar Graph or Line Graph</p>
        </div>
      </div>
      <div class="col-sm-4 col-4">
        <div class="red">
          <p>numbers</p>
        </div>
        <div class="purple">
          <p>numbers</p>
        </div>
        <div class="green">
          <p>numbers</p>
        </div>
        <div class="blue">
          <p>numbers</p>
        </div>
      </div>
  </div>
</div>

和CSS:

p { color: #fff; }
.black { background-color: black; }
.green { background-color: green; }
.red { background-color: red; }
.blue { background-color: blue; }
.purple { background-color: purple; }

推荐答案

您可以使用 flexbox .

另一种方式:

https://jsfiddle.net/persianturtle/ar0m0p3a/5/

.row-eq-height > [class^=col] {
  display: flex;
  flex-direction: column;
}

.row-eq-height > [class^=col]:last-of-type div {
  margin: 10px;
}

.row-eq-height > [class^=col]:last-of-type div:first-of-type {
  margin-top: 0;
}

.row-eq-height > [class^=col]:last-of-type div:last-of-type {
  margin-bottom: 0;
}

.row-eq-height > [class^=col]:first-of-type .black {
  flex-grow: 1;
}

更新

使用更具体的类的更好方法:

Update

A better way with more specific classes:

https://jsfiddle.net/persianturtle/ar0m0p3a/3/

.row-eq-height > [class^=col]:first-of-type {
  display: flex;
}

.row-eq-height > [class^=col]:first-of-type .black {
  flex-grow: 1;
}

.blue p {
  margin: 0;
}

原始方式:

https://jsfiddle.net/persianturtle/ar0m0p3a/1/

[class^=col] {
  display: flex;
  flex-direction: column;
}

[class^=col] div {
  flex-grow: 1
}
