Bootstrap 4粘页脚不粘 [英] Bootstrap 4 Sticky Footer Not Sticking
问题描述
不太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.
粘性页脚未粘在页面底部.
此处是页面源的副本，已呈现.
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，则页脚不会停留-我必须向下滚动页面才能看到它.

更新2020-Bootstrap 4.5 +
现在，Bootstrap 4是 flexbox ，使用flexbox粘贴页脚会更容易.
<div class="d-flex flex-column sticky-footer-wrapper">
<nav>
</nav>
<main class="flex-fill">
</main>
<footer>
</footer>
</div>
body, .sticky-footer-wrapper {
min-height:100vh;
}
.flex-fill {
flex:1 1 auto;
}
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实用程序包含在Bootstrap 4.1中稍后发布.因此，在该版本发布之后，就不需要多余的CSS来进行flex-fill填充.

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.

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 sticky-footer-wrapper">
<nav>
</nav>
<main class="flex-fill">
</main>
<footer>
</footer>
</div>
body, .sticky-footer-wrapper {
min-height:100vh;
}
.flex-fill {
flex:1 1 auto;
}
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.
