🧰 Technologies Used:

• HTML5 – Structure and content layout

• CSS3 – Animations, text glow, confetti styling, balloon float

• JavaScript – Interactive animations, confetti physics, event triggers

🎈 Features:

• “🎉 Happy Birthday” animated headline

• Colorful confetti falling across the screen

• Bouncing or floating balloons using keyframes

• Optional background music or sound trigger

• Fully responsive and lightweight

• Can be customized for names, colors, or messages

🎬 How It Works:

1. The animation is built around a central HTML heading and decorative elements.

2. CSS keyframes are used to animate balloons and background glow.

3. JavaScript triggers dynamic confetti animations or physics-based movement.

4. Optional music or interaction (e.g., click to burst balloon or replay) can be added.

💡 Tip: You can customize the font, timing, balloon count, and colors to match the birthday person’s theme!

🧠 Learning Highlights:
