Upon opening my HTML file, I am unable to locate the collapse button on the navbar. The collapsible button seems to be missing. Here is a snippet of my HTML code:
<!DOCTYPE html>
<html>
<head>
<title>BoostUp - Boost your projects</title>
<link href="/assets/css/boostrap/bootstrap.min.css" rel="stylesheet">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="./assets/css/heroes.css">
<link rel="stylesheet" href="./assets/css/style.css">
</head>
<body>
<nav class="navbar navbar-expand-lg navbar-light bg-white">
<div class="container-fluid">
<a class="navbar-brand" href="#">
<img src="/assets/img/logo.png" alt="" width="30" height="24" class="d-inline-block align-text-top">
BoostUp
</a>
<div class="collapse navbar-collapse" id="navbarNavDropdown">
<ul class="navbar-nav">
<li class="nav-item">
<a class="nav-link active" aria-current="page" href="index.html">Home</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">SEO</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Posts</a>
</li>
</ul>
</div>
</div>
</nav>
</div>
<script src="./assets/js/jquery.js"></script>
<script src="/assets/js/booststrap/bootstrap.bundle.min.js"></script>
<script src="https://www.gstatic.com/firebasejs/8.6.1/firebase-app.js"></script>
<script src="./assets/js/firestart.js"></script>
</body>
</html>
Note: Currently using Bootstrap 5.
