bootstrap 4 导航栏在左侧和右侧有填充
[英]bootstrap 4 navbar has padding on left and right side
问题描述
I'm not sure what I'm missing here, I know I can add the CSS to take away the padding from the parent div but I thought that bootstrap would make the navbar the full width of the page?
我不确定我在这里缺少什么，我知道我可以添加 CSS 以从父 div 中删除填充，但我认为引导程序会使导航栏成为页面的全宽？ Here's my code:这是我的代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">
<title>Contact</title>

<div class="container-fluid" id="outer">

<nav class="navbar navbar-expand-lg navbar-light bg-secondary">
<a class="navbar-brand" href="#">

The container-fluid class is 100% wide, but it has some padding applied.容器流体类是 100% 宽的，但它应用了一些填充。 To manage the padding you can use p-* classes from Bootstrap 4 (read the spacing section from the documentation).要管理填充，您可以使用Bootstrap 4 中的p-*类（阅读文档中的间距部分）。 In your particular case, you need the p-0 class to remove the padding.在您的特定情况下，您需要p-0类来删除填充。 As an extra, I have added the collpase menu button, if you don't include it your navbar will not work correctly when collapsed.另外，我添加了折叠菜单按钮，如果您不包含它，您的navbar在折叠时将无法正常工作。 Check the next example:检查下一个示例：
