Bootstrap 4行填充剩余高度

Question

我正在努力使一行伸展以填充剩余的可用高度。我尝试将h-100 添加到行类中，但这会导致屏幕底部出现空白。一定有办法做到这一点，但我完全被难住了。这是我的代码：

<div class="container-fluid h-100">
  <div class="row justify-content-center h-100">
    <div class="col-4 bg-red">
      <div class="h-100">
        <div class="row justify-content-center bg-purple">
          <div class="text-white">
            <div style="height:200px">ROW 1</div>
          </div>
        </div>
        <div class="row justify-content-center bg-blue">
          <div class="text-white">ROW 2</div>
        </div>
      </div>
    </div>
    <div class="col-8 bg-gray"></div>
  </div>
</div>

我想让蓝色行 (ROW 2) 填满所有红色空间。有什么建议吗？

谢谢

使用Bootstrap 4.1 flex-grow-1 类...

html,body{height:100%;}

.bg-purple {
  background: rgb(48,0,50);
}
.bg-gray {
  background: rgb(74,74,74);
}
.bg-blue {
  background: rgb(50,101,196);
}
.bg-red {
  background: rgb(196,50,53);
}

<div class="container-fluid h-100">
  <div class="row justify-content-center h-100">
    <div class="col-4 bg-red">
      <div class="h-100 d-flex flex-column">
        <div class="row justify-content-center bg-purple">
          <div class="text-white">
            <div style="height:150px">ROW 1 - fixed height</div>
          </div>
        </div>
        <div class="row justify-content-center bg-blue flex-grow-1">
          <div class="text-white">ROW 2 - grow remaining height</div>
        </div>
      </div>
    </div>
    <div class="col-8 bg-gray"></div>
  </div>
</div>

更新 4.3.1：另一个使用 vh-100 实用程序类的示例

.bg-purple {
  background: rgb(48,0,50);
}
.bg-gray {
  background: rgb(74,74,74);
}
.bg-blue {
  background: rgb(50,101,196);
}
.bg-red {
  background: rgb(196,50,53);
}

<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.3.1/css/bootstrap.min.css" integrity="sha384-ggOyR0iXCbMQv3Xipma34MD+dH/1fQ784/j6cY/iJTQUOhcWr7x9JvoRxT2MZw1T" crossorigin="anonymous">

<div class="container-fluid">
  <div class="row justify-content-center min-vh-100">
    <div class="col-4 bg-red">
      <div class="d-flex flex-column h-100">
        <div class="row justify-content-center bg-purple">
          <div class="text-white">
            <div style="height:150px">ROW 1 - fixed height</div>
          </div>
        </div>
        <div class="row justify-content-center bg-blue flex-grow-1">
          <div class="text-white">ROW 2 - grow remaining height</div>
        </div>
      </div>
    </div>
    <div class="col-8 bg-gray"></div>
  </div>
</div>

Answer 2

这是一个解决方案。包装器div 必须有h-100，适应高度的div 必须有flex-grow-1 和overflow-auto。这样，div 将在其内容小于可用空间时填充空间，并在其内容高于可用空间时显示滚动条。

Demo jsfiddle

<div class="h-100 d-flex flex-column bg-yellow px-2">
<div class="flex-column justify-content-center bg-purple px-2">        
    <div class="text-white p-0" style="height:50px">HEADER</div>
</div>

<div class="flex-column justify-content-center bg-red text-white px-2 flex-grow-1 overflow-auto">

        <div>Item1</div>
        <div>Item2</div>
        INNER text 1<br>
        INNER text 2<br>

</div>

<div class="flex-column justify-content-center bg-darkblue px-2">
    <div class="text-white p-0" style="height:50px">FOOTER</div>
</div>                

Answer 3

如果有人厌倦了让它工作，这里有一个超级简单的解决方案，可以在大多数情况下工作。只需将以下类添加到您尝试填充剩余高度的 div 中： 请注意，100vh 是可见高度的 100%，而 200px 是上面剩余 div 的总固定高度。

.fillRemaining {
height: calc(100vh - 200px);
}
