BootStrap NavBar在Safari上不起作用

Question

我通过验证程序运行了网站，结果全为绿色。我有hrefs，对我来说代码似乎很干净。但是，汉堡包不想在野生动物园中使用吗？

<nav class="navbar fixed-top navbar-expand-sm navbar-dark bg-dark" id="main-nav">
    <div class="container">
        <a href="#navbarNav" class="navbar-brand" id="logo">kurkweb</a>
        <button class="navbar-toggler" data-toggle="collapse" data-target="#navbarNav">
            <span class="navbar-toggler-icon"></span>
        </button>
        <div class="collapse navbar-collapse" id="navbarNav">
            <ul class="navbar-nav ml-auto">
                <li class="nav-item">
                    <a href="#logos" class="nav-link">logos</a>
                </li>
                <li class="nav-item">
                    <a href="#web" class="nav-link">web</a>
                </li>
                <li class="nav-item">
                    <a href="#ui" class="nav-link">ui/ux</a>
                </li>
            </ul>
        </div>
    </div>
</nav>
