无法使用css和 Bootstrap 使导航元素居中

我想要的是有我的导航栏品牌集中在所有平台和我的导航项目/链接，包括导航栏切换定位在右边。
现在它在大屏幕上看起来就像this.，而且我根本无法使它居中。
但是如果我把它缩小到991px以下，导航栏就会居中，尽管很奇怪，而且没有与项目正确对齐。
On smaller screens
我正在使用引导单独和我的css文件没有任何东西在它还没有。
我试过在我的css文件中覆盖它，但它根本不会居中。我读过bootstrap的文档，但我似乎不能使它工作。
我很确定这和导航条扩展lg有关，因为它会影响导航条链接和导航条品牌（居中）缩小到991px以下。
下面是我的代码：

<div class="collapse navbar-collapse" id="navbarTogglerDemo01">
                <ul class="navbar-nav ms-auto ">
                    <li class="nav-item">
                        <a class="nav-link" href="#">Link 1</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="#">Link 2</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="#">Link 3</a>
                    </li>
                </ul>
                </div>
            </div>
            </nav>

css

由于.navbar-toggler占用的空间，.navbar-brand与.nav-link不对齐。借助BS's position utility classes，您可以将.navbar-toggler的大小从等式中排除。您需要将.position-relative添加到.container-fluid，将.position-absolute.top-0.end-0添加到.navbar-toggler。切换器将从流中移除，并定位在右上角，其他所有内容都保持在容器宽度的中心位置。
通过将.justify-content-center.flex-wrap添加到容器，将.w-100添加到品牌，可以使展开视图中的所有内容都以两行为中心。
