html - 为什么我的
    Bootstrap 5中的元素总是溢出？

问题描述

我的界面中有一个包含很多元素的元素。一旦列表扩展到整个屏幕，滚动条就会出现在列表中。该元素通过 flex-grow 设置为占用 Right 列中剩余的高度空间。如果没有列表元素，该元素会完美地填充剩余的高度。但是，一旦元素中一个屏幕的元素太多，整个标签和屏幕就会溢出。

元素在<div id=content">元素空间上的高度溢出，<body>尽管我将 bodymax-height属性设置为100vh对我来说似乎不合适。

这是我的代码的一个小例子： Codepen

如何调整代码以显示在 y 轴上显示滚动条的许多元素的元素？

html,
body {
  height: 100vh;
  max-height: 100vh;
}

解决方案

通过向flex-grow 父元素和子元素添加属性，我能够使用此答案解决问题。min-height=0
