💡 Bulb Switch Project || Light Bulb Toggle || Free Source Code || Web Dev Projects
🌟 Project Overview:
In this video, you'll learn how to create a light bulb switch effect using pure HTML, CSS (via Tailwind & Bootstrap), and JavaScript. The UI is sleek, responsive, and interactive—ideal for beginners looking to grasp DOM manipulation and event handling.

When the user toggles the switch, the bulb image dynamically updates to an "on" or "off" state in real-time. This project is an excellent mini-project for practicing basic web development concepts, especially conditional rendering, DOM access, and event listeners.

💻 What You’ll Learn:
How to create a responsive layout using TailwindCSS and Bootstrap

How to implement a toggle switch that controls an image element

How to use JavaScript to dynamically change image sources

Real-world application of event listeners with onclick

Minimalist design structure for better UX/UI practice

🔧 Tech Stack Used:
HTML5

CSS3 (TailwindCSS & Bootstrap)

JavaScript (Vanilla)

🎯 Why This Project?
This project is perfect for:

Beginners looking to build small, impactful projects

Web dev learners exploring interactive UI components

Those practicing DOM manipulation and responsive design

You can integrate similar interactivity into bigger projects like smart home dashboards, IoT device UIs, or personal portfolios.

📌 How It Works (Code Summary):
A switch is created using Bootstrap’s form-switch.

The lightSwitch() function detects whether the toggle is turned on or off.

Based on the switch state, it either calls bulb_on() or bulb_off().

Each of these functions simply changes the image src attribute to represent a lit or unlit bulb using pre-defined URLs.

The logic is simple, clean, and serves as a great learning example for real-time UI changes.
