这是我目前的导航栏与标志在中间居中，但现在我需要添加一个搜索栏和一些图标，如：ideal navbar
My current navbar的

<header>
    <nav class="navbar navbar-expand-md ">
        <div id="nav" class="container-fluid">
            <a class="navbar-brand d-md-none" href="index.html">
                <img src="relogo.png" alt="">
            </a>
            <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-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 mx-auto">
                    <li class="nav-item">
                        <a class="nav-link active" aria-current="page" href="produkte.html">PRODUKTE</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="#">ANBIETER</a>
                    </li>
                    <a class="navbar-brand d-none d-md-block" href="index.html">
                        <img src="relogo.png" alt="">
                    </a>
                    <li class="nav-item">
                        <a class="nav-link" href="#">ÜBER UNS</a>
                    </li>
                    <li class="nav-item">
                        <a class="nav-link" href="kontakt.html">KONTAKT</a>
                    </li>
                </ul>
            </div>
        </div>
    </nav>
</header>

字符串
在导航栏的最后一行添加，但现在徽标不再居中，图标位于current<li> <form class="d-flex"> <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search"> </form> </li>下方
