Question

我正在尝试将我的导航栏放在我的Jumbotron封面上（我正在使用Bootstrap CSS），但我无法将它（导航栏）放置在Jumbotron顶部，具有透明背景。

帮助将不胜感激： - ）

将fixed-top导航栏用作explained in the docs ...

<nav class="navbar navbar-expand-md navbar-light fixed-top">
    <div class="navbar-collapse collapse w-100 order-1 order-md-0 dual-collapse2">
        <ul class="navbar-nav mr-auto">
            <li class="nav-item active">
                <a class="nav-link" href="/home.php">Item 1</a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="">Item 2</a>
            </li>
        </ul>
    </div>

    <div class="mx-auto order-0">
        <a class="navbar-brand mx-auto" href="/home.php">
            <img src="/images/logo.svgs" height="35" alt="">Logo
        </a>
    </div>

    <div class="navbar-collapse collapse w-100 order-3 dual-collapse2">
