html - 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。我尝试添加h-100到行类，但这会导致屏幕底部出现空白。必须有办法做到这一点，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（第 2 行）填满所有红色空间。有什么建议么？

谢谢

使用Bootstrap 4.1flex-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);
}

<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>
