Tailwind CSS empowers developers to build stylish and responsive user interfaces with ease. It offers a comprehensive set of utility classes, making it a preferred choice for front-end development.
Before we dive into the intricacies of building this navigation masterpiece, let's ensure you have the right tools at your disposal and understand the fundamentals of Tailwind CSS. This tutorial will equip you with the skills to create a visually appealing and user-friendly navigation bar for your web project.
Source Code
Step 1 (HTML Code):
To get started, we will first need to create a basic HTML file. In this file, we will include the main structure for our navbar.
After creating the files just paste the following codes into your file. Make sure to save your HTML document with a .html extension, so that it can be properly viewed in a web browser.
Let's break down the code step by step:
1. <!DOCTYPE html>: This declaration defines the document type and version of HTML being used, which is HTML5 in this case.
2. <html lang="en">: This is the opening tag for the HTML document. It specifies that the document is in English (lang="en"), indicating the language for the content.
3. <head>: This is the head section of the HTML document, where you typically include metadata and links to external resources.
- <title>: Sets the title of the webpage that appears in the browser's title bar or tab.
- <meta charset="UTF-8">: Defines the character encoding of the document as UTF-8, which is a widely used character encoding for handling text.
- <meta name="viewport" content="width=device-width">: Specifies how the webpage should be displayed on different devices by adjusting the viewport width to the device's screen width.
- <script src="https://cdn.tailwindcss.com"></script>: Includes an external JavaScript file from the Tailwind CSS CDN (Content Delivery Network). This script provides styling and functionality to the navbar.
4. <body>: This is the body section of the HTML document, where the visible content of the webpage is placed.
5. <nav>: This is a navigation bar element, often used to display menu options and links.
- class="bg-white ...": Assigns various CSS classes from the Tailwind CSS framework to style the navigation bar with a white background, shadows, and other visual effects.
- Inside the <nav> element, there is a container <div> that uses the Tailwind CSS classes to control its appearance.
- <a>: This is a link to a website, and it contains an image and text.
- <img src="...">: An image element with a source URL pointing to a logo image.
- <span>: A text element containing the name "CodewithFaraz."
6. <button>: This is a button element used for toggling the navigation menu on smaller screens (e.g., mobile devices). It has an associated ID ("navbar-toggle") and various CSS classes to style it.
- Inside the button, there is an <svg> element that represents an icon (a menu icon) using vector graphics.
7. <div id="navbar-dropdown">: This is a container for the dropdown menu that appears when the button is clicked. It is initially hidden (hidden class) and becomes visible on smaller screens.
8. Inside this <div>, there is an unordered list <ul> containing a list of menu items, each represented by an <li> element.
- <a> elements represent individual menu items with links to different sections of the website. These links have various classes to style them differently, including color changes on hover.
- The "Product" menu item has a sub-menu that appears as a dropdown. It is represented by another <button> element and a nested <div> containing more menu items.
- The sub-menu items also have links with hover effects and are visually separated from each other.
9. <script src="script.js"></script>: This script tag includes an external JavaScript file called "script.js," which contains additional functionality for the webpage.
This is the basic structure of our navbar with multi-level dropdown menus using HTML, and now we can move on to styling it using CSS.
Step 2 (CSS Code):

*/ Step 3 (JavaScript Code):
Finally, we need to create a function in JavaScript. Let's break down what each part of the code does:
1. document.addEventListener('DOMContentLoaded', function () { ... });
- This code listens for the "DOMContentLoaded" event on the webpage, which occurs when the HTML document has been fully loaded and parsed.
- When the event is fired (i.e., the webpage is ready), it executes the provided function, which contains the rest of the code.
2. const button = document.getElementById('navbar-toggle');
- This line selects an HTML element with the ID "navbar-toggle" and stores it in the variable button.
3. const menu = document.getElementById('navbar-dropdown');
- This line selects an HTML element with the ID "navbar-dropdown" and stores it in the variable menu.
4. const dropdownButton = document.getElementById('dropdownNavbarLink');
- This line selects an HTML element with the ID "dropdownNavbarLink" and stores it in the variable dropdownButton.
5. const dropdownMenu = document.getElementById('dropdownNavbar');
- This line selects an HTML element with the ID "dropdownNavbar" and stores it in the variable dropdownMenu.
6. const doubleDropdownButton = document.getElementById('doubleDropdownButton');
- This line selects an HTML element with the ID "doubleDropdownButton" and stores it in the variable doubleDropdownButton.
7. const doubleDropdown = document.getElementById('doubleDropdown');
- This line selects an HTML element with the ID "doubleDropdown" and stores it in the variable doubleDropdown.
8. dropdownButton.addEventListener('click', () => { ... });
- This code adds a click event listener to the dropdownButton element.
- When the dropdownButton is clicked, the provided arrow function is executed.
- Inside the arrow function, the classList.toggle('hidden') method is used to toggle the "hidden" class on the dropdownMenu. This can hide or show the dropdown menu, depending on its current state.
9. doubleDropdownButton.addEventListener('click', () => { ... });
- Similarly, this code adds a click event listener to the doubleDropdownButton element.
- When the doubleDropdownButton is clicked, the provided arrow function is executed.
- Inside the arrow function, the classList.toggle('hidden') method is used to toggle the "hidden" class on the doubleDropdown. This can hide or show another dropdown menu.
10. button.addEventListener('click', function () { ... });
- This code adds a click event listener to the button element.
- When the button is clicked, the provided function is executed.
- Inside the function, the classList.toggle('hidden') method is used to toggle the "hidden" class on the menu. This can hide or show a navigation menu.
Create a JavaScript file with the name script.js and paste the given codes into your JavaScript file and make sure it's linked properly to your HTML document so that the scripts are executed on the page. Remember, you’ve to create a file with .js extension.
document.addEventListener('DOMContentLoaded', function () {
const button = document.getElementById('navbar-toggle');
const menu = document.getElementById('navbar-dropdown');
const dropdownButton = document.getElementById('dropdownNavbarLink');
const dropdownMenu = document.getElementById('dropdownNavbar');
const doubleDropdownButton = document.getElementById('doubleDropdownButton');
const doubleDropdown = document.getElementById('doubleDropdown');
dropdownButton.addEventListener('click', () => {
dropdownMenu.classList.toggle('hidden');
});
doubleDropdownButton.addEventListener('click', () => {
doubleDropdown.classList.toggle('hidden');
});
button.addEventListener('click', function () {
menu.classList.toggle('hidden');
});
});Final Output:
