Bootstrap提供了一种轻松快捷的方法来创建基本的导航组件,例如标签和药丸,它们非常灵活,美观。 Bootstrap的所有导航组件(选项卡和药丸)都通过基本的.nav类共享相同的基本标记和样式。
如果你想创建一个简单的水平导航栏,可以在 <ul> 元素上添加 .nav类,在每个 <li> 选项上添加 .nav-item 类,在每个链接上添加 .nav-link 类:

.justify-content-center 类设置导航居中显示, .justify-content-end 类设置导航右对齐。

.flex-column 类用于创建垂直导航:

使用 .nav-tabs 类可以将导航转化为选项卡。然后对于选中的选项使用 .active 类来标记。

.nav-pills 类可以将导航项设置成胶囊形状。

.nav-justified 类可以设置导航项齐行等宽显示。

如果你要设置选项卡是动态可切换的,可以在每个链接上添加 data-toggle="tab" 属性。 然后在每个选项对应的内容的上添加 .tab-pane 类。
如果你希望有淡入效果可以在 .tab-pane 后添加 .fade类:

胶囊状动态选项卡只需要将以上示例的代码中 data-toggle 属性设置为 data-toggle="pill":
