如何在 WordPress 中将 Bootstrap 菜单项居中？

Question

我正在尝试将作为 Bootstrap 导航菜单一部分的项目居中。

  <nav class="navbar navbar-toggleable-md navbar-light bg-faded navbar-expand-md" style="background-color: yellow; font-size: 30px";>
    <button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
    <a class="navbar-brand" href="#">LOGO</a>
    <div class="collapse navbar-collapse" id="navbarNavDropdown">
       <?php
          wp_nav_menu( array(
                    'theme_location'    => 'primary',
                    'depth'             => 2,
                    'container_id'      => 'bs-example-navbar-collapse-1',
                    'menu_class'        => 'nav navbar-nav navbar-right',
                    'fallback_cb'       => 'WP_Bootstrap_Navwalker::fallback',
                    'walker'            => new WP_Bootstrap_Navwalker())
                );
          ?>
         </div>
     </nav>

现在，我的 WordPress 菜单中有 5 个项目。我正在努力做到这一点，导航栏品牌在左边，第一个菜单在中间，三个菜单项在右边，最后一个菜单项在最后。

|Logo| |first| |second||third||fourth| |fifth|

标志navbar-brand默认在左边，我设法把第五个菜单项放在右边

  .menu-item:nth-child(5) {
        position: absolute;
        right: 0px;
    }

现在我需要将第一个项目居中，然后将其余项目向右推。我试过做

  .menu-item:nth-child(1) a {
        margin: 0 auto;
    }

但它不起作用。

要在 Bootstrap 4 中完成它，您需要将 3 个组中的每一个都包装在它们自己的 <ul> 中，并将 ml-auto 类添加到其中。

这是一个有效的 HTML sn-p（单击下面的“运行代码 sn-p”并展开到整页）：

<nav class="navbar navbar-expand-md navbar-light bg-light">
    <a class="navbar-brand" href="#">Navbar</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>

    <div class="collapse navbar-collapse" id="navbarSupportedContent">
        <ul class="navbar-nav ml-auto">
            <li class="nav-item">
                <a class="nav-link" href="#">Link1</a>
            </li>
        </ul>
        <ul class="navbar-nav ml-auto">
            <li class="nav-item">
                <a class="nav-link" href="#">Link2</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Link3</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Link4</a>
            </li>
        </ul>
        <ul class="navbar-nav ml-auto">
            <li class="nav-item">
                <a class="nav-link" href="#">Link5</a>
            </li>
        </ul>
    </div>
</nav>

另请注意：navbar-toggleable-md 类在 Bootstrap 4 中不存在。
