引导带向左浮动和向右浮动 [英] Bootstrap float left and float right

问题描述

我是新手，所以对大多数人来说这可能是一个简单的问题.我有一个导航栏，想要两个导航项和一个输入字段位于导航栏的左侧.剩下的两个导航项在右边.我试图弄乱这些类以使其发生，并使用"float-left"和"float-right"类，但没有任何乐趣:(

I'm very new to bootstrap so this is probably an easy question for most. I have a navbar, want two nav items and an input field to be on the left side of the navbar. With the two remaining nav items on the right. I have tried messing with the classes to make this happen and using the "float-left" and "float-right" classes but no joy :(

<nav class="navbar fixed-top navbar-expand-lg navbar-dark bg-dark fixed-top">
      <div class="container">
        <a class="navbar-brand" href="index.php">L'amour</a>
        <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
          <span class="navbar-toggler-icon"></span>
        </button>
        <div class="collapse navbar-collapse" id="navbarResponsive">
          <ul class="navbar-nav ml-auto">
            <li class="nav-item float-left">
              <a class="nav-link float-left" href="order.php">Contact Us</a>
            </li>
            <li class="nav-item float-left">
              <a class="nav-link float-left" href="order.php">Testimonial</a>
            </li>
            <li class="nav-item">
              <input class='form-control' type='text' name='search' placeholder='Search for wedding...'>
            </li>
            <li class="nav-item float-right">
              <a class="nav-link float-right" href="order.php">Order Wesbite</a>
            </li>
            <li class="nav-item dropdown float-right">
              <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownBlog" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
             Account
              </a>
              <div class="dropdown-menu dropdown-menu-right" aria-labelledby="navbarDropdownBlog">
                <a class="dropdown-item" href="signIn.php">Login</a>
                <a class="dropdown-item" href="sign-up">Sign up</a>
                <a class="dropdown-item" href="homeUser.php">Account details</a>
                <a class="dropdown-item" href="logout.php">Logout</a>
              </div>
            </li>
          </ul>
        </div>
      </div>
    </nav>
