Bootstrap 4.5.3 navbar toggle is not working

Mahmoud Khosravi

I am working on a navbar that was made out of HTML CSS and Bootstrap. I had followed some tutorials on youtube but I can seem to expand the toggle button when the screen size is reduced to the smallest. Since I'm starting a new project, I applied all of this with HTML CSS, and Bootstrap and opened the HTML file in my local directory.

<!doctype html>
<html lang="fa" dir="rtl">
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

        </button>
        <div class="collapse navbar-collapse" id="navbarNav">
          <ul class="navbar-nav justify-content-center">

I created a codeply for you, there is no error in your code, you just need to add a few <script>s into your code. I recommend you to use the cdn.

In order to make the hamburger button work, the necessary lines of code are needed:

<head>
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/css/bootstrap.min.css" integrity="sha384-TX8t27EcRE3e/ihU7zmQxVncDAy5uIKz4rEkgIXeMed4M0jlfIDPvg6uqKI2xXr2" crossorigin="anonymous">
</head>
<body>


<script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/umd/popper.min.js" integrity="sha384-9/reFTGAW83EW2RDu2S0VKaIzap3H66lZH81PoYlFhbGU+6BZp6G7niu735Sk7lN" crossorigin="anonymous"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.min.js" integrity="sha384-w1Q4orYjBQndcko6MimVbzY0tgp4pWB4lZ7lr30WKz0vr/aWKhXdBNmNb5D92v7s" crossorigin="anonymous"></script>
</body>

Make sure you include these lines of code in this specific order.
