            </nav>
        </div>
    </body>
</html>

Answer 1

由于您正在使用Bootstrap IV，因此需要使用navbar navbar-dark bg-dark而不是navbar navbar-inverse。

Answer 2

您包括Boostrap4。但是您的代码适用于Bootstrap 3。这应该可以完成您在Bootstrap 4中所需的操作。

.active{
  background:#000;
}

<div class="container">
    <nav class="navbar navbar-expand-md navbar-dark bg-dark">
        <div class="navbar-header">
            <a class="navbar-brand" href="#">WebSiteName</a>
        </div>

        <div class="collapse navbar-collapse" id="navbarNavAltMarkup">
            <ul class="navbar-nav">
                <li><a class="nav-item nav-link active" href="#">Home </a></li>
                <li><a class="nav-item nav-link" href="#">Page 1</a></li>
                <li><a class="nav-item nav-link" href="#">Page 2</a></li>
                <li><a class="nav-item nav-link" href="#">Page 3</a></li>
            </ul>
        </div>
    </nav>
</div>

Answer 3

使用以下代码，您可以得到最接近的外观。在大屏幕上，链接将整体显示。链接将在小屏幕上折叠。

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" rel="stylesheet"/>

<nav class="navbar navbar-expand-lg navbar-dark bg-dark">
        <a class="navbar-brand" href="#">Website Name</a>
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="navbarNav" aria-expanded="false" aria-label="Toggle navigation">
            <span class="navbar-toggler-icon"></span>
        </button>
        <div class="collapse navbar-collapse" id="navbarNav">
            <ul class="navbar-nav">
                <li class="nav-item active">
                    <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Page 1</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link" href="#">Page 2</a>
                </li>
                <li class="nav-item">
                    <a class="nav-link disabled" href="#">Page 3</a>
                </li>
            </ul>
        </div>
    </nav>
