当我加载另一个网页时，div 会变小，页脚会根据 div 中的内容上下移动。

谁能帮我看看为什么会这样。

我的代码(与使用 Flask 略有不同):

最佳答案

这是因为 div 容器没有固定的高度。如果你想让它成为一个固定的高度，只需将它添加到你的文件中

HTML:

改变这个

<div class="container">

到

<div class="container fixed-height">

CSS:

将此添加到 css 文件

div.fixed-height {
height: 900px !important;
}

您可以将高度更改为任何您想要的高度。如果您只是想将页脚保持在页面底部，我也不建议这样做。如果您浏览互联网，还有其他方法可以做到这一点。
