javascript - Bootstrap 4 导航栏右对齐搜索选项以及注册

Question

我正在尝试创建一个带有 Serch 选项和登录选项的导航栏。我想让“搜索”选项在“注册”选项之前右对齐。我需要一些帮助。

提前致谢。

下面是我的代码。

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css">

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

Answer 1

<nav class="navbar navbar-expand-md navbar-dark bg-dark fixed-top">
<div class="container">
   <a href="#" class="navbar-brand "><i class="fa fa-camera-retro"></i> Photo Galary</a> 
   <div class="collapse navbar-collapse" id="navbarSupportedContent">
      <ul class="nav navbar-nav ml-auto">
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
           <span class="navbar-toggler-icon"></span>
           </button>
           <form class="form-inline my-2 my-lg-0">
              <div class="input-group">
                 <input type="text" class="form-control border border-right-0" placeholder="Search...">
                 <span class="input-group-append">
                 <button class="btn btn-outline-light border border-left-0" type="button">
                 <i class="fa fa-search"></i>
                 </button>
                 </span>
              </div>
           </form>
         <li class="nav-item ">
            <a class="nav-link" href="#">Sign Up <i class="fa fa-user-plus"></i></a>
         </li>
         <li class="nav-item ">
            <a class="nav-link" href="#">Login <i class="fa fa-user"></i></a>
         </li>
      </ul>
   </div>
</div> </nav>

在 Bootstrap-4 中，float-right 不起作用，因为 Bootstrap 现在是一个 flexBox。您可以使用ml-auto。
