问题描述

不确定为什么粘性页脚在 Bootstrap 4 中不起作用.我有一个 TYPO3 网站，我是初学者.

粘性页脚未粘贴在页面底部.

这是已呈现的页面源的副本.

我基本上是从 bootstraps docs 文件夹中复制 html 文件，然后对其进行修改并将其复制到我的 TYPO3 模板中.

如果我用内容填充页面，页脚不会粘住 - 我必须向下滚动页面才能看到它.

<html lang="zh-cn"><头><meta charset="utf-8"><title>登陆页面</title><meta name="generator" content="TYPO3 CMS"><link rel="stylesheet" type="text/css"href="/typo3temp/assets/css/d42b6e1bdf.css?1507853162" media="all"><link rel="stylesheet" type="text/css"href="/fileadmin/templates/landing_page/css/bootstrap.min.css?1507860230"媒体=所有"><link rel="stylesheet" type="text/css"href="/fileadmin/templates/landing_page/css/sticky-footer.css?1507861966"媒体=所有"><脚本src="/fileadmin/templates/landing_page/js/jquery-3.2.1.min.js?1507862465"type="text/javascript"></script><脚本src="/fileadmin/templates/landing_page/js/tether.min.js?1507862602"type="text/javascript"></script><脚本src="/fileadmin/templates/landing_page/js/bootstrap.min.js?1507854311"type="text/javascript"></script><身体><div class="容器"><div class="mt-1"><h1>粘性页脚</h1>

<p class="lead">将固定高度的页脚固定到使用此自定义 HTML 和 CSS 的桌面浏览器中的视口.</p><p>使用 粘性页脚固定导航栏如果需要，也是.</p><div class="row"><div class="col">1 of 3</div><div class="col">1 of 3</div><div class="col">1 of 3</div>

<footer class="footer"><div class="容器"><span class="text-muted">在此处放置粘性页脚内容.</span>

</页脚></html>

解决方案

2020 年更新 - Bootstrap 4.5+

现在 Bootstrap 4 是 flexbox，使用 flexbox 制作粘性页脚会更容易.

<导航></nav><主类=flex-fill"></main><页脚></页脚>

Bootstrap 4.0 粘性页脚 (4.0.0)
底部示例的简单页脚 (4.5.0)

注意:flex-fill 实用程序是 包含在以后的 Bootstrap 4.1 中 版本.所以在那之后发布额外的 flex-fill 的 CSS 将不再需要.此外，min-vh-100 包含在较新的 Bootstrap 4 版本中.

Not really sure why the sticky footer isn't working in Bootstrap 4. I have a TYPO3 website which I am a beginner at.

The sticky footer is not sticking at the bottom of the page.

Here is a copy of the page source as it has been rendered.

I basically copied the html file from bootstraps docs folder and then modified it and copied it into my TYPO3 template.

If I fill the page with content, the footer does not stick - I have to scroll the page down to see it.

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">

<title>Landing Page</title>
<meta name="generator" content="TYPO3 CMS">

<link rel="stylesheet" type="text/css"
	href="/typo3temp/assets/css/d42b6e1bdf.css?1507853162" media="all">
<link rel="stylesheet" type="text/css"
	href="/fileadmin/templates/landing_page/css/bootstrap.min.css?1507860230"
	media="all">
<link rel="stylesheet" type="text/css"
	href="/fileadmin/templates/landing_page/css/sticky-footer.css?1507861966"
	media="all">

<script
	src="/fileadmin/templates/landing_page/js/jquery-3.2.1.min.js?1507862465"
	type="text/javascript"></script>
<script
	src="/fileadmin/templates/landing_page/js/tether.min.js?1507862602"
	type="text/javascript"></script>
<script
	src="/fileadmin/templates/landing_page/js/bootstrap.min.js?1507854311"
	type="text/javascript"></script>

</head>
<body>
	<div class="container">
		<div class="mt-1">
			<h1>Sticky footer</h1>
		</div>
		<p class="lead">Pin a fixed-height footer to the bottom of the
			viewport in desktop browsers with this custom HTML and CSS.</p>
		<p>
			Use <a href="../sticky-footer-navbar">the sticky footer with a
				fixed navbar</a> if need be, too.
		</p>
		<div class="row">
			<div class="col">1 of 3</div>
			<div class="col">1 of 3</div>
			<div class="col">1 of 3</div>
		</div>
	</div>

	<footer class="footer">
		<div class="container">
			<span class="text-muted">Place sticky footer content here.</span>
		</div>
	</footer>
</body>
</html>

解决方案

Update 2020 - Bootstrap 4.5+

Now that Bootstrap 4 is flexbox, it's easier to use flexbox for the sticky footer.

<div class="d-flex flex-column min-vh-100">
    <nav>
    </nav>
    <main class="flex-fill">
    </main>
    <footer>
    </footer>
</div>

Bootstrap 4.0 Sticky Footer (4.0.0)
Simple Footer at Bottom Example (4.5.0)

Note: The flex-fill utility was included in Bootstrap 4.1 at later release. So after that release the extra CSS for flex-fill won't be needed. Additionally min-vh-100 is included in newer Bootstrap 4 releases.
