Technical Specification: Free Online Fraction Simplifier

Overview

This application is a specialized math utility designed to reduce any fraction to its lowest terms. The tool features a clean, professional, and accessible user interface, optimized for students, teachers, and professionals requiring rapid fraction reduction without unnecessary complexity.

Core Features

• Real-time Simplification: Instant reduction of fractions as the user types or clicks the 'Simplify' action.
• Step-by-Step Breakdown: Visual explanation of the Greatest Common Divisor (GCD) extraction method.
• Input Validation: Intelligent handling of non-numeric input, zero denominators, and empty fields.
• Copy to Clipboard: One-tap button to copy the resulting fraction.
• Responsive Design: Fluid layout that adjusts seamlessly from mobile devices to desktop monitors.
• Light-Mode Aesthetic: A high-contrast, clean professional design utilizing whitespace for maximum focus.

User Interface Layout

1. Header: A simple, centered header containing the app name and a brief instruction subtitle.
2. Input Section: Two clearly labeled input fields (Numerator, Denominator) using floating labels for a modern SaaS feel. A prominent action button labeled 'Simplify' styled with a primary blue accent color.
3. Result Section: A large, visually distinct card displaying the simplified fraction. Below this, a 'Calculation Steps' section that expands/collapses.
4. Information Section: A small text area explaining the utility of the tool for SEO purposes.

Design System & Aesthetics

• Typography: Sans-serif font stack (Inter, system-ui, -apple-system, sans-serif).
• Color Palette:
  • Background: #FFFFFF (Pure White) and #F9FAFB (Subtle Light Gray for containers).
  • Primary: #2563EB (Professional Blue) for buttons and key actions.
  • Text: #1F2937 (Dark Gray) for readability.
  • Borders/Dividers: #E5E7EB (Light Gray).
• Animations: Subtle CSS transitions (ease-in-out) for button hover states, modal reveals, and result rendering. No jarring movements.

Technical Directives

• Architecture: Single-file HTML structure. All styles must be contained within a <style> block and logic within a <script> block.
• Sandboxed Constraints:
  • DO NOT use localStorage, sessionStorage, or cookies.
  • DO NOT use alert(), prompt(), or confirm(). Implement custom UI modal overlays for all user interaction messages.
  • All external links must have target="_blank" and rel="noopener noreferrer".
• Performance: No heavy external dependencies. Use vanilla JavaScript for all mathematical logic (Euclidean algorithm for GCD).
• Accessibility: Ensure all inputs have associated <label> elements or ARIA labels. The application must support keyboard-only navigation.
