Question

我有一个导航栏折叠按钮，但下拉列表中的项目没有对齐。我认为这与我的 div 设置方式有关。我该如何解决？

<nav class="navbar navbar-expand-md navbar-light mb-4 row">
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarCollapse" aria-controls="navbarCollapse" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>
    
    <div class="col-4 text-left collapse navbar-collapse" id="navbarCollapse">
          <ul class="navbar-nav mr-auto">
            <li class="nav-item" id="better_candidate">
                <a class="nav-link" href="">A Better Candidate</a>
            <li class="nav-item" id="better_employer">
                <a class="nav-link" href="">A Better Employer</a>
            <li class="nav-item" id="better_stuff">
                <a class="nav-link" href="">Better Stuff</a>
          </ul>
            </div>

    <div class="col-4 text-center">
        <a class="navbar-brand" href="{% url 'a_better_place:home' %}">
            A Better Place
        </a>
    </div>

    <div class="col-4 text-right collapse navbar-collapse" id="navbarCollapse">
          <ul class="navbar-nav ml-auto">
                <li class="nav-item" id="about_us">
                    <a class="nav-link" href=""> About Us </a>
              <li class="nav-item" id="contact">
                  <a class="nav-link" href="{% url 'a_better_place:contact' %}">
                      Contact
                  </a>   
          </ul>
          
      </div>
</nav>

通常，导航栏中不使用 col 和 row，如果您要拥有两个 navbar-collapse 列表，则不能为它们提供相同的 ID .相反，您可以使用一个类并在导航栏切换器的 data-target 中使用该类名。

要在大屏幕上将品牌置于中心位置，您可以使用弹性顺序。
