Question

我正在努力使我的品牌名称显示在左上角，而我的主要导航栏按钮位于顶部中央。然后，我还希望另一个下拉菜单位于最右侧。我已将右侧的品牌名称和单个按钮正确对齐，但中间的按钮未正确居中。

这是我的代码：

    <nav class="navbar navbar-expand-lg navbar-dark" style="background-color: rgb(35,35,35);">
        <div class="container-fluid">
            <a href="a" style="text-decoration: none;"><span class="navbar-brand mb-0 h1">a</span></a>
            
            <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
                <span class="navbar-toggler-icon"></span>
            </button>

            <div class="collapse navbar-collapse justify-content-center" id="navbarNav">
                <div class="navbar-nav">
                    <a class="nav-link mx-2" href="index">a</a>
                    <li class="nav-item dropdown mx-2">
                        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-bs-toggle="dropdown" aria-expanded="false">a</a>
                        <ul class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
                            <li><a class="dropdown-item" href="a">a</a></li>
                            <li><a class="dropdown-item" href="a">a</a></li>
                            <li><a class="dropdown-item" href="a">a</a></li>
                        </ul>
                    </li>
                    <a class="nav-link mx-2" href="a">a</a>
                    <li class="nav-item dropdown mx-2">
                        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-bs-toggle="dropdown" aria-expanded="false">a</a>
                        <ul class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
                            <li><a class="dropdown-item" href="a">a</a></li>
                            <li><a class="dropdown-item" href="a">a</a></li>
                            <li><a class="dropdown-item" href="a">a</a></li>
                        </ul>
                    </li>
                </div>
            </div>

            <div class="collapse navbar-collapse justify-content-end" id="navbarNav">
                <div class="navbar-nav">
                    <li class="nav-item dropdown mx-2">
                        <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-bs-toggle="dropdown" aria-expanded="false">a</a>
                        <ul class="dropdown-menu dropdown-menu-end" aria-labelledby="navbarDropdownMenuLink">
                            <li><a class="dropdown-item" href="games">a</a></li>
                            <li><a class="dropdown-item" href="software">a</a></li>
                        </ul>
                    </li>
                </div>
            </div>

        </div>
    </nav>

我认为您可以通过将三个元素（品牌、主导航和右侧下拉菜单）的样式设置为 w-100 来获得所需的效果。浏览器应将您的主导航定位在其他两个元素之间的中心。

<link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/css/bootstrap.min.css" rel="stylesheet"/>
<script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.2/dist/js/bootstrap.bundle.min.js"></script>

<style>
    @media (min-width:576px) {
        .w-sm-100 {
            width: 100% !important;
        }
    }
</style>

<nav class="navbar navbar-expand-sm navbar-dark" style="background-color: rgb(35,35,35);">
    <div class="container-fluid">
        <a class="w-sm-100" href="a" style="text-decoration: none;"><span class="navbar-brand mb-0 h1">a</span></a>

        <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>

        <div class="collapse navbar-collapse justify-content-center w-sm-100" id="navbarNav">
            <div class="navbar-nav">
                <a class="nav-link mx-2" href="index">alfa</a>
                <li class="nav-item dropdown mx-2">
                    <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-bs-toggle="dropdown" aria-expanded="false">alpha</a>
                    <ul class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">

                    </ul>
                </li>
                <a class="nav-link mx-2" href="a">bravo</a>
                <li class="nav-item dropdown mx-2">
                    <a class="nav-link dropdown-toggle" href="#" id="navbarDropdownMenuLink" role="button" data-bs-toggle="dropdown" aria-expanded="false">beta</a>
                    <ul class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
