Bootstrap提供了一種輕松快捷的方法來(lái)創(chuàng)建基本的導(dǎo)航組件，例如標(biāo)簽和藥丸，它們非常靈活，美觀(guān)。 Bootstrap的所有導(dǎo)航組件（選項(xiàng)卡和藥丸）都通過(guò)基本的.nav類(lèi)共享相同的基本標(biāo)記和樣式。
如果你想創(chuàng)建一個(gè)簡(jiǎn)單的水平導(dǎo)航欄，可以在 <ul> 元素上添加 .nav類(lèi)，在每個(gè) <li> 選項(xiàng)上添加 .nav-item 類(lèi)，在每個(gè)鏈接上添加 .nav-link 類(lèi):

.justify-content-center 類(lèi)設(shè)置導(dǎo)航居中顯示， .justify-content-end 類(lèi)設(shè)置導(dǎo)航右對(duì)齊。

.flex-column 類(lèi)用于創(chuàng)建垂直導(dǎo)航：

使用 .nav-tabs 類(lèi)可以將導(dǎo)航轉(zhuǎn)化為選項(xiàng)卡。然后對(duì)于選中的選項(xiàng)使用 .active 類(lèi)來(lái)標(biāo)記。

如果你要設(shè)置選項(xiàng)卡是動(dòng)態(tài)可切換的，可以在每個(gè)鏈接上添加 data-toggle="tab" 屬性。 然后在每個(gè)選項(xiàng)對(duì)應(yīng)的內(nèi)容的上添加 .tab-pane 類(lèi)。
如果你希望有淡入效果可以在 .tab-pane 后添加 .fade類(lèi):
