柱子不占全高
Column doesnt take the full hight
我有一个问题：
正如您在图片中看到的那样，问题是该列没有占据全部高度。左边是我得到的，右边是我想要的。也许你们可以帮助我。这是导致左侧图像的源代码。我已经搜索了一个解决方案，但不幸的是没有适合我的源代码的东西。

所以我编辑了一些 类 并添加了一些 类。

本题与 and 基本相同，但你使用的Bootstrap网格结构过于复杂，嵌套不正确，几乎不可能做出高度按预期工作。
如果您 , the height issue is resolved using the flexbox grow and shrink utilities 如 Bootstrap 文档中所述...
"Use .flex-grow-* utilities to toggle a flex item’s ability to grow to
fill available space. "
使用 vh-100、flex-grow-0、flex-grow-1、flex-column 等...
<div class="container-fluid d-flex flex-column vh-100">
<nav class="navbar navbar-expand-lg navbar-light bg-light">
...
</nav>
<div class="row flex-grow-1">
<div class="col-md-4 bg-warning">
<!-- this is the left side -->
</div>
<div class="col-md-8 bg-primary d-flex flex-column flex-grow-1">
<div class="row flex-column flex-fill">
<div class="col bg-success flex-grow-0">
<div class="row">
<!-- it should be the full width but unfortunatelly a scrollbar appears because of this section right here... -->
</div>
</div>
<div class="col bg-info flex-fill">
<!-- Should be in the middle and full screen (like the area where you and another person have a conversation--> Message </div>
<!-- should be at the bottom of the Screen like in everyother Chat-->
<div class="col bg-success flex-grow-0"> Text-Input and Button </div>
