如何将搜索表单放置在导航栏中间并在 Bootstrap 中展开 5

Question

我正在使用 Bootstrap v5.1.3 并且添加了这样的导航栏：

navbar

这里是代码：

        <div class="container">
            <nav class="navbar navbar-expand-lg navbar-light bg-light">
                <div class="container-fluid">
                    <a class="navbar-brand" href="#">Navbar</a>
                    <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
                        <span class="navbar-toggler-icon"></span>
                    </button>
                    <div class="collapse navbar-collapse" id="navbarSupportedContent">
                        <form class="d-flex">
                            <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
                            <button class="btn btn-outline-success" type="submit">Search</button>
                        </form>
                        <ul class="navbar-nav ms-auto mb-2 mb-lg-0">
                            <li class="nav-item dropdown">
                                <a class="nav-link dropdown-toggle" id="navbarDropdown" href="#" role="button" data-bs-toggle="dropdown" aria-expanded="false">Cart</a>
                                <ul class="dropdown-menu dropdown-menu-end" aria-labelledby="navbarDropdown">
                                    <li><a class="dropdown-item" href="#">Action</a></li>
                                    <li><a class="dropdown-item" href="#">Another action</a></li>
                                    <li><hr class="dropdown-divider" /></li>
                                    <li><a class="dropdown-item" href="#">Something else here</a></li>
                                </ul>
                            </li>
                        </ul>
                    </div>
                </div>
            </nav>
        </div>

但是我需要扩展搜索表单并将其放在导航栏的中心，所以它看起来像这样：

expected search form example

所以我尝试将 id 添加到表单中：

<form class="d-flex" id="search">

并添加了这个：

#search{
   text-align:center;
}

但还是不行，左边显示了搜索表单。

那么如何将此搜索表单放置在导航栏的中间并在 Bootstrap 5 中将其展开一点？

使用flex-grow-1使其展开...

<div class="container">
    <nav class="navbar navbar-expand-lg navbar-light bg-light">
        <div class="container-fluid">
            <a class="navbar-brand" href="#">Navbar</a>
            <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
                <span class="navbar-toggler-icon"></span>
            </button>
            <div class="collapse navbar-collapse" id="navbarSupportedContent">
                <form class="d-flex flex-grow-1">
                    <input class="form-control me-2" type="search" placeholder="Search" aria-label="Search">
                    <button class="btn btn-outline-success" type="submit">Search</button>
                </form>
                <ul class="navbar-nav ms-auto mb-2 mb-lg-0">
                    <li class="nav-item dropdown">
                        <a class="nav-link dropdown-toggle" id="navbarDropdown" href="#" role="button" data-bs-toggle="dropdown" aria-expanded="false">Cart</a>
                        <ul class="dropdown-menu dropdown-menu-end" aria-labelledby="navbarDropdown">
                            <li><a class="dropdown-item" href="#">Action</a></li>
                            <li><a class="dropdown-item" href="#">Another action</a></li>
                            <li>
                                <hr class="dropdown-divider" />
                            </li>
                            <li><a class="dropdown-item" href="#">Something else here</a></li>
                        </ul>
                    </li>
                </ul>
            </div>
        </div>
    </nav>
</div>
