如何防止我的引導導航欄在移動設備上折疊（我希望它顯示一個漢堡包）？ 我的第一個 CSS 項目

Question

如何防止我的引導導航欄在移動設備上折疊（我希望它顯示一個漢堡包）？ 抱歉，如果這是一個愚蠢的問題，這是我的第一個 CSS 項目。

這是我使用引導類的導航欄...

 <nav class="navbar navbar-expand-lg "> 
    <div class="container-fluid">
      <button class="navbar-toggler" type="button" data-bs-toggle="collapse" data-bs-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
         <span class="navbar-toggler-icon"></span> 
      </button>
      <div class="collapse navbar-collapse justify-content-center" id="navbarNavAltMarkup">
        <div class="navbar-nav">
          <a class="nav-link active" aria-current="page" href="#">Home</a>
          <a class="nav-link active" aria-current="page" href="#menu">Menu</a>
          <a class="nav-link active" aria-current="page" href="#">Our Story</a>
          <a class="nav-link active" aria-current="page" href="https://www.indeed.com/">Careers</a>
          <a class="nav-link active" aria-current="page" href="#contact">Contact</a>
         
        </div>
      </div>
    </div>
  </nav>

始終檢查 Bootstrap 提供的文檔。 這里有你需要的

 <link href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap/5.0.2/css/bootstrap.min.css" rel="stylesheet"/> <script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap/5.1.3/js/bootstrap.min.js"></script> <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"> <ul class="navbar-nav me-auto mb-2 mb-lg-0"> <li class="nav-item"> <a class="nav-link active" aria-current="page" href="#">Home</a> </li> <li class="nav-item"> <a class="nav-link" href="#">Link</a> </li> <li class="nav-item dropdown"> <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-bs-toggle="dropdown" aria-expanded="false"> Dropdown </a> <ul class="dropdown-menu" 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> <li class="nav-item"> <a class="nav-link disabled" href="#" tabindex="-1" aria-disabled="true">Disabled</a> </li> </ul> <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> </div> </div> </nav>
