Question

正如您所看到的，在大，中，小屏幕上，页脚具有正确的背景默认颜色（由于panel_footer类），但是，只要三个部分相互堆叠，您就可以看到部分页脚颜色与页面的背景颜色。如何以一种颜色均匀的方式设置页脚的样式？

这里的代码：

<!DOCTYPE html>
<html lang="en">

<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">

  <header>
    <nav id="mainheader" class="navbar navbar-default">

Answer 1

在CSS中，从页脚中删除高度：

#footer {
  height:200px;
}

如您所做的那样定义此高度将调整列堆叠上的默认Bootstrap行为。如果您想维护此属性，请在较大的设备上，在各自的媒体查询上进行定义。

E.g：

@media (max-width: 768px) {
  #footer {
    height: 200px;
  }
}

这是Working Fiddle的链接。

<小时/> PS（与问题无关）：您正在导入您的css文件：

<link rel="stylesheet" href="C:\Users\Gianpa\Desktop\banco di prova coding\sito prova\css\bootstrap.min.css">
<link rel="stylesheet" href="C:\Users\Gianpa\Desktop\banco di prova coding\sito prova\css\banco prova css.css">

我建议重命名＆＃34; banco prova css.css＆＃34; to＆＃34; banco_prova_css.css＆＃34;，并从CDN导入Bootstrap的css，例如：

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
