Bootstrap5 导航栏
更新时间：2021-10-23 21:23导航栏一般放在页面的顶部。我们可以使用 .navbar 类来创建一个标准的导航栏，后面紧跟: .navbar-expand-xxl|xl|lg|md|sm 类来创建响应式的导航栏 (大屏幕水平铺开，小屏幕垂直堆叠)。导航栏上的选项可以使用 <ul> 元素并添加 class="navbar-nav" 类。 然后在 <li> 元素上添加 .nav-item 类， <a> 元素上使用 .nav-link 类:

通过添加 .justify-content-center 类来创建居中对齐的导航栏:

<h3>导航栏居中对齐</h3>
<p>使用 .justify-content-center 类设置导航栏居中对齐</p>
<p>在这个实例中，不管屏幕尺寸是大的还是超大的都会居中对齐，在手机设备上会设置右边折叠显示，因为使用了 .navbar-expand-sm 类。</p>

</html>不同颜色导航栏
可以使用以下类来创建不同颜色导航栏：.bg-primary, .bg-success, .bg-info, .bg-warning, .bg-danger, .bg-secondary, .bg-dark 和 .bg-light)。提示: 对于暗色背景 .navbar-dark 需要设置文本颜色为浅色的，对于浅色背景 .navbar-light 需要设置文本颜色为深色的。
