使用 Bootstrap 4 在大屏幕上的导航栏和小屏幕上的导航栏导航之间切换
Switch between nav-pills on large screen and navbar-nav on smaller screen with Bootstrap 4
我喜欢大屏幕上导航药丸的外观,但一旦显示折叠按钮,我希望该菜单可以堆叠并且看起来像附加的图像而不是药丸。我需要自定义 css 才能实现吗?
<div id="menu" class="navbar navbar-expand-md">
<button class="navbar-toggler" type="button" data-toggle="collapse" data-target=".main-nav-collapse" aria-controls="main-nav-collapse" aria-expanded="true" aria-label="Toggle navigation">
<span class="fa fa-bars"></span>
</button>
<div class="collapse navbar-collapse main-nav-collapse">
<nav class="nav nav-pills mr-auto">
<a class="nav-link" href="/"><i class="fa fa-home"></i></a>
</nav>
</div>
</div>
希望在较小的屏幕上显示此内容
希望这些药片在更大的屏幕上显示,但不要更小
您可以在此处切换 class 和 d-none
和 d-flex
。
为什么这里d-flex
而不是d-block
因为.nav
class是用flexbox制作的,flex比block更舒服。
