我正在尝试使用Serch选项和Login选项创建一个导航栏。我想使“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。

        <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...">

在Bootstrap-4 float-right将无法工作，因为引导是现在flexBox。您可以使用ml-auto。
