+# HCF Calculator
+
+This is a simple and attractive Highest Common Factor (HCF) Calculator built using HTML, CSS, and JavaScript. The design features a neon theme with a linear gradient background, popups for invalid inputs, and a visually appealing user interface.
+
+## Features
+
+- Calculate the HCF of two numbers
+- Neon-themed UI with gradient background
+- Popup for invalid input handling
+- Responsive design
+
+## Files
+
+The project consists of three main files:
+
+1. `index.html` - The HTML structure of the calculator.
+2. `styles.css` - The CSS file for styling the calculator.
+3. `script.js` - The JavaScript file containing the logic for HCF calculation and input validation.
