带滚动内容的 Bootstrap 5 固定高度容器

Question

这是我目前拥有的代码 - 我希望只有在滚动容器视口（例如：.scrollable）后才能看到“最后一项”。 现在它会调整父级以适应，因此只有主 html/body 滚动条显示。 这可以使用 flexbox 实用程序吗？ 帮助！ :)

<div class="container-fluid h-100 ">
    <div class="row h-100">
        <div class="col">
            <div class="h-100 d-flex flex-column">
                <div class="row my-3">

                    <div class="col">
                        <input type="text" class="form-control form-control-lg" placeholder="Input"
                               aria-label="First name">
                    </div>
                    <div class="col">

请记住， h-100是相对于父级的高度而言的，并且父级必须具有定义的高度。 因此，在要作为视口高度的元素上使用vh-100 overflow-hidden 。 强制可滚动容器的父级保持在该高度内。 最后在可滚动元素上使用overflow-auto ...

<div class="container-fluid">
    <div class="row">
        <div class="col">
            <div class="d-flex flex-column vh-100 overflow-hidden">
                <div class="row my-3">
