We will begin by creating an HTML file and setting up a template with the necessary elements. To attach the bar icon to the menu, we will use the Font Awesome CDN link.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">

    <link rel="stylesheet" href="style.css">
    <!-- Load an icon library to show a hamburger menu: -->
    <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/6.4.0/css/all.min.css">
</head>
<body>

    <!-- To create a navigation  menu and bar -->
    <div class="navbar">
        <div class="nav_1">
            <a href="#" class="">KED_KULTURE</a>

            <div id="menu">
                <a href="#">About</a>
                <a href="#">Contact Us</a>
                <a href="#">Catalogue</a>
                <a href="#">Register/Login</a>
            </div>

            <!-- To create the icon link for navigation -->
            <a href="javascript:void(0);" class="icon" onclick="Ked_kulture()">
                <i onclick ="Ked_kulture()" class="fa fa-bars"></i>
            </a>
        </div>
    </div>
    <script src="index.js"></script>
</body>

The above is the HTML part of the source code linked to the CSS and JavaScript files for styling and to add some functionality. My sole aim of writing this article is to help my readers fully understand whatever concept they want to learn. I know the "href" assigned to the bar icon for navigation may be new to some of us, but don't worry, I will explain it in the JavaScript session.

Now, let's move on to the CSS styling:

body{
    background-color: peachpuff;
}

/* To style the Navbar */
.navbar{
    background-color: black;
    border-radius: 1rem;
    margin: 50px;
    height: 500px;
    max-width: 450px;
    box-shadow: 5px 5px grey;
}

/* To style the logo */
.nav_1{
    position: relative;
}


/* To style the navigation menu */
.nav_1 #menu{
    display: none;
}

/* To style the links */
.nav_1 a {
    text-decoration: none;
    color: white;
    padding: 10px 12px;
    font-size: 16px;
    display: block;
}

/* To style the Navigation bar toggle bar */
.nav_1 a.icon {
    display: block;
    position: absolute;
    right: 0;
    top: 0;
}

/* To add an hover effect on navigation logo and menu */
.nav_1 a:hover {
    background-color: #b9b1b1;
    color: black;
            }

Let's define the function in JavaScript:

// Function to toggle the bar
function Ked_kulture() {
    var btn = document.getElementById("menu");
    if (btn.style.display === "block") {
        btn.style.display = "none";
    } 
    else {
        btn.style.display = "block";
    }
}

Here, "javaScript;" is often referred to as a pseudo URL. When "javascript:" is assigned as the value of the "href" attribute on an anchor tag, the code that follows after the colon is interpreted as JavaScript code. Using "javascript:", you can run code that does not change the current page. This is useful in cases where you do not want a link to navigate to another page or reload the current page. When used with "void(0)", it means to do nothing – does not reload, does not navigate, and does not run any code. "void(0)" evaluates the given expression and returns undefined.

Hope this is clear enough.
