A well-designed navbar is essential for any website, providing users with a clear and intuitive way to navigate through the site. In this article, we will explore the key components of a navbar and how to implement them using HTML, CSS, and JavaScript.

Understanding the Navbar Components

A typical navbar consists of several key components, including:

Logo: The logo is usually placed on the left side of the navbar and serves as the site's branding.
Participant Information: This section typically displays the participant's username and a sign-out button.
Language Selector: A dropdown menu that allows users to select their preferred language.
Navigation Links: These are the links that allow users to navigate through the site.

Implementing the Navbar

To implement the navbar, we will use HTML, CSS, and JavaScript. We will start by creating the HTML structure for the navbar.

HTML Structure

<nav class="navbar">
    <div class="logo">
        <img src="logo.png" alt="ROAR Logo">
    </div>
    <div class="participant-info">
        <p>Welcome, <strong>Participant Username</strong></p>
        <button class="sign-out-btn">Sign Out</button>
    </div>
    <div class="language-selector">
        <select>
            <option value="en">English</option>
            <option value="fr">French</option>
            <option value="es">Spanish</option>
        </select>
    </div>
</nav>

CSS Styling

.navbar {
    background-color: #333;
    padding: 1rem;
    display: flex;
    justify-content: space-between;
    align-items: center;
}

.logo {
    margin-left: 1rem;
}

.logo img {
    width: 100px;
    height: 50px;
    object-fit: contain;
}

.participant-info {
    margin-right: 1rem;
}

.participant-info p {
    margin-bottom: 0.5rem;
}

.sign-out-btn {
    background-color: #333;
    border: none;
    padding: 0.5rem 1rem;
    cursor: pointer;
}

.sign-out-btn:hover {
    background-color: #444;
}

.language-selector {
    margin-right: 1rem;
}

.language-selector select {
    padding: 0.5rem 1rem;
    border: none;
    border-radius: 0.25rem;
    cursor: pointer;
}

JavaScript Implementation

To implement the navbar, we will use JavaScript to add event listeners to the sign-out button and the language selector.

const signOutBtn = document.querySelector('.sign-out-btn');
const languageSelector = document.querySelector('.language-selector select');

signOutBtn.addEventListener('click', () => {
    // Implement sign-out logic here
    console.log('Sign out button clicked');
});

languageSelector.addEventListener('change', () => {
    // Implement language change logic here
    console.log('Language changed to:', languageSelector.value);
});

Testing the Navbar

To test the navbar, we will use a student account with a username and password to login into the dashboard.

Login into the Dashboard

To login into the dashboard, we will use the following credentials:

Username: participant_username
Password: password

Expected Results

After logging in, we expect the following results:

ROAR Logo: The ROAR logo should be visible on the left side of the screen.
Participant Username: The participant's username should be visible on the top right corner of the screen.
Sign Out Button: The sign-out button should be visible next to the participant's username and should highlight when the mouse covers it.
Language Selector: A dropdown menu should be visible on the right side of the screen, allowing users to select their preferred language.

Conclusion

In this article, we explored the key components of a navbar and how to implement them using HTML, CSS, and JavaScript. We created a basic navbar structure, styled it using CSS, and added event listeners to the sign-out button and the language selector using JavaScript. We also tested the navbar using a student account with a username and password to login into the dashboard and verified the expected results.
