Question

在container-fluid cont下，我正在使用引导程序编写自定义导航栏。

问题是当我单击切换开关（humburger）时，什么都不会显示。相反，我希望当以移动尺寸查看它时，它会折叠并且当我单击切换开关时，它应该显示ul链接列表。我可以更改什么？

<!-- NAV BAR -->
<nav class="navbar fixed-top navbar-expand-sm navbar-custom navbar-light">
    <a class="navbar-brand js-scroll-trigger" href="index.html"><img src="images/logo.png" height="50px" width="auto"></a>

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

    <div class="collapse navbar-collapse" id="navbarCustom">
        <ul class="navbar-nav mr-auto mt-2 mt-lg-0">
            <li class="nav-item active samecolor">
                <a class="nav-link" href="#home">HOME</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#orari">ORARI</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#luogo">DOVE SIAMO</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="about.hmtl">CHI SIAMO</a>
            </li>
        </ul>
    </div>  
</nav>

这些是我在 css 方面所做的一些更改：

/*CHANGING SOME BOOTS TRAP NAV*/
.navbar-custom { 
    background-color: #F5D236; 
} 

.navbar-custom .navbar-nav .nav-link {
    color: #223D94;
}

/* change the color of active or hovered links */
.navbar-custom .nav-item.active .nav-link,
.navbar-custom .nav-item:hover .nav-link {
    color: #223D94;
}

.navbar-custom .dropdown-item {
    color: #223D94;
}
