Calculator Project

Introduction

Welcome to the Calculator Project! This project showcases a simple web-based calculator built with HTML, CSS, and JavaScript. It provides basic arithmetic functionality, allowing users to perform addition, subtraction, multiplication, and division operations.

Project Components

The Calculator Project consists of the following key components:

1. HTML Structure

The HTML file (index.html) defines the structure of the calculator web page. It includes:

• A display area for input and output.
• Numeric buttons for digits 0-9 and the decimal point.
• Function buttons for basic operations (addition, subtraction, multiplication, division).
• Special buttons for clearing input and performing calculations.

2. CSS Styling

The CSS stylesheet (style.css) provides the visual styling for the calculator:

• It defines the overall layout, color scheme, and button styles.
• Functional buttons are styled differently for easy identification.
• The calculator container has rounded corners and a modern appearance.

3. JavaScript Functionality

The JavaScript code (calculator.js) adds interactivity to the calculator:

• It handles button clicks, updating the input and display accordingly.
• Arithmetic operations are performed based on user input.
• The eval function is used to evaluate mathematical expressions.
• The calculator provides a responsive and user-friendly experience.

Usage

To use the calculator, simply click the buttons to input digits and operations. Press the "=" button to calculate the result. The calculator is designed to handle basic mathematical calculations with ease.

Future Enhancements

This calculator project can be further improved and expanded:

• Adding support for more advanced operations (e.g., square root, exponentiation).
• Implementing keyboard input for enhanced usability.
• Enhancing the visual design and responsiveness for various devices.

Conclusion

The Calculator Project is a practical example of web development using HTML, CSS, and JavaScript. It serves as a foundation for creating more sophisticated calculator applications or integrating similar functionality into larger web projects.

Feel free to explore the code, modify it, or use it as a learning resource for your web development journey. Happy calculating!
