CodeAlpha: Digital Calculator 🧮

A modern, responsive digital calculator built from scratch as part of the Frontend Development Internship at CodeAlpha. This application features a highly tactile user interface designed to handle real-time arithmetic expressions smoothly.

🚀 Features

• [cite_start]Core Math Engine: Handles all basic arithmetic operations perfectly (+, -, ×, ÷)[cite: 28].
• Tactile UI/UX: Built with a balanced dark theme and an interactive CSS Grid layout. Buttons scale down dynamically when clicked to give a highly physical, tactile feel.
• [cite_start]Advanced Keyboard Support: Includes a custom event listener that maps your physical keyboard numpad directly to the application[cite: 30]. You can type numbers, operators, press Enter for the result, Backspace to delete a single character, or Escape to clear.
• Responsive Layout: Automatically scales down to fit mobile screens perfectly without losing its alignment.

🛠️ Tech Stack

• HTML5: Semantic architecture for layout boxes and display inputs.
• CSS3: Built using modern styling parameters, native variable definitions, and transitions.
• JavaScript (ES6+): Utilizes full Event Delegation, keydown listeners, data-attribute extraction, and expression evaluation engines.
