我目前正在使用bootstrap处理一些小事。这里我有一个导航栏。对于导航项"登录"和"退出"我已将其设置为使用justify-content-end
保持在右侧。在大屏幕设备上,它是我想要的。但是,当我使用移动设备打开它时,导航栏会按照其意图折叠,但justify-content-end
的项目不会显示。
有什么想法吗? 谢谢
<nav class="navbar navbar-expand-lg navbar-dark bg-primary">

<button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">

<div class="collapse navbar-collapse justify-content-end" id="navbarNavAltMarkup">

<?php
if (!$this->session->userdata('logged_in'))
echo '<a class="nav-link" href="'.base_url().'/Login">Login</a>';
else echo '<a class="nav-link" href="#">Logout</a>';
?>
</ul>

答案 0 :(得分:1)
HTML格式不正确(应该在li里面,而li缺少结束括号)。但是,问题是你已经命名了两个具有相同id
但不起作用的元素。只需使用类名(即:navbar-alt)切换collapse
个导航栏,并在data-target
中定位此类。
