Bootstrap 4 Scrollable Div 占用剩余的中间屏幕高度

Question

我正在尝试设计一个带有 Bootstrap 4 和 6 个 div 的页面，我需要 DIV #4 占据剩余高度并可滚动。

Divs 1-3会略微动态，不是固定高度。 Div 5 和 6 是一样的。 Div 4 应该会占据屏幕的剩余部分，但内容可能会更长，因此需要滚动。

Answer 1

如评论所示，flexbox 是您想要制作的三明治风格。但是，我相信它是在 4.1 之后引入的。因此，此解决方案仅在您的 bootstrap 版本 >= 4.1.

时有效

你的代码有一些错误。您正在使用内联样式作为 class 这样 class="flex-grow: 0"，您可以将它们放入 style="flex-grow: 0" 或 class="flex-grow-0".

要保持最后 <div> 或任何你想要的 <div> 的固定高度，你可以给它一个 height: somenumberhere px 或 height: somenumberhere vh.
