问题描述
对于Bootstrap 4，我希望有一行可以填满页面的剩余高度，但其中的内容不应使高度超出给定的位置.内容应该可以通过按钮滚动，滚动条最多应该是不可见的.
With Bootstrap 4 I would like to have a row, which fills up the remaining height of the page, but the content of it should not extend the height over the place given. The content should be scrollable by buttons, the scrollbar at best should not be visible.
我试图将我的布局分解为这个.请随时纠正-这确实不是我的强项.
I tried to break down my layout to this. Please feel free to correct - this is really not my strong suit.
HTML:
<!doctype html>
<html lang="de">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<link rel="stylesheet" type="text/css" href="/library/bootstrap-4.1.0/css/bootstrap.min.css">
<link rel="stylesheet" type="text/css" href="/library/fontawesome-5.0.10/css/fontawesome-all.min.css">
<link rel="stylesheet" type="text/css" href="/css/screen/presentation.css"/>
<title>Test</title>
</head>
<body>
<div id="wrapper">
<div id="sidebar-wrapper">
<ul class="sidebar-nav">
<li>Test 1</li>
<li>Test 2</li>
<li>Test 3</li>
</ul>
</div>
<div id="page-content-wrapper">
<div class="container-fluid d-flex h-100 flex-column">
<div class="row">
<div class="col">
<a href="#menu-toggle" class="btn btn-light" id="menu-toggle"><i class="fas fa-bars fa-3x"></i></a>
</div>
</div>
<div class="container h-100 flex-column d-flex">
<div class="row">
<div class="col headline-col bg-warning">
<h5 class="align-middle">Headline 1</h5>
</div>
</div>
<div class="section-div h-100 flex-column d-flex">
<div class="row bg-success">
<div class="col">
<h5>Subtitle 1</h5>
</div>
</div>
<div class="row flex-fill bg-danger d-flex">
<div class="col">
<h5>Subtitle 2</h5>
<p>
This should fill the remaining height, but the content should not use more space than available.
So it should be scrollable, best without scrollbar and scrolling by buttons
</p>
</div>
</div>
</div>
</div>
<div class="container">
<div class="row">
<div class="col last-col bg-success text-right">
This should always be at the bottom of the page.
<button class="btn btn-primary btn-scroll-up" type="button">Sroll Up</button>
<button class="btn btn-primary btn-scroll-down" type="button">Scroll Down</button>

});
非常感谢！
推荐答案
I had a similar issue: Flexbox height issue with nested flex-grow boxes in Bootstrap 4
而不是使用h-100.这将迫使容器为视口高度的100％，而不是剩余高度，请使用Bootstrap 4.1 flex grow utils ...
Instead of using h-100. which will force the containers to be 100% of viewport height rather than remaining height, use the Bootstrap 4.1 flex grow utils...
-
flex-grow-1填充弹性容器的剩余高度 -
flex-shrink-0使其他行缩小而不会挤压
flex-grow-1to fill remaining height of flex containerflex-shrink-0to make other rows shrink without squishing
然后在相应的div上设置overflow:auto以便其滚动.
Then set overflow:auto on the appropriate div so that it scrolls.
