Bootstrap 4 導航欄右對齊搜索選項以及注冊

Question

我正在嘗試創建一個帶有 Serch 選項和登錄選項的導航欄。 我想讓“搜索”選項在“注冊”選項之前右對齊。 我需要一些幫助。

提前致謝。

下面是我的代碼。

 <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css"> <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> <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> <div class="collapse navbar-collapse" id="navbarSupportedContent"> <ul class="nav navbar-nav ml-auto"> <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>

<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 float-right將不起作用，因為 Bootstrap 現在是flexBox 。 您可以使用ml-auto 。
