Add DrumKit Project

[PThanushree]

Hello! I’d love to contribute to the DrumKit project.
I noticed that while the app plays basic drum sounds, there’s room to enhance the experience with additional features and visual improvements.

💡 Proposed Changes

Add more drum sounds (e.g., crash cymbal, tom-tom, ride).
Implement smooth key press animations when a user clicks or presses a key.
Make the layout responsive for mobile and tablet screens.
Optionally, add a simple volume control slider.

🧩 Why This Would Help
These updates will make the DrumKit app feel more realistic, interactive, and user-friendly — especially for mobile users.

⚙️ Technical Approach

Add new sound files (.mp3) to the sounds/ folder.
Map them to new keys in JavaScript.
Use CSS transitions for button/key animations.
Test responsiveness with Flexbox or CSS Grid.
