gamma-page System Requirements Document

1. Introduction

The purpose of this document is to outline the system requirements for the "gamma-page" project. This project aims to create a simple, single-page design for a calculator application, focusing on basic simplicity without any specific additional requirements.

2. System Overview

The gamma-page project is a web-based application designed to provide users with a straightforward calculator interface. The application will be accessible via a single web page, ensuring ease of use and simplicity. The primary goal is to deliver a functional and intuitive calculator experience without unnecessary complexity.

3. Functional Requirements

• As a User, I should be able to perform basic arithmetic operations such as addition, subtraction, multiplication, and division.
• As a User, I should be able to clear the current input to start a new calculation.
• As a User, I should be able to view the results of my calculations immediately after entering the operation.

4. User Personas

• User: An individual seeking a simple and efficient tool for performing basic arithmetic calculations.

5. Core User Flows

• User opens the calculator page -> User inputs numbers and selects an operation -> User views the result -> User clears the input for a new calculation.

6. Visuals Colors and Theme

• primary: #3498db (a calm blue for the main interface)
• primary_light: #85c1e9 (a lighter blue for hover states)
• secondary: #2ecc71 (a green hue for buttons and emphasis)
• accent: #e74c3c (a vibrant red for active states and CTAs)
• highlight: #f1c40f (a warm yellow for notifications and active indicators)
• bg: #ecf0f1 (a light grey for the page background)
• surface: rgba(255, 255, 255, 0.9) (a white surface for cards/panels)
• text: #2c3e50 (a dark blue for primary text)
• text_muted: #7f8c8d (a muted grey for secondary text)
• border: rgba(44, 62, 80, 0.2) (a subtle border color)

7. Signature Design Concept

The gamma-page calculator will feature an interactive "flip card" design. Each button on the calculator will appear as a card that physically flips when clicked, providing a tactile and engaging user experience. The flipping animation will be smooth and responsive, utilizing framer-motion for spring physics. The background will have a subtle gradient that shifts slightly as users interact with the calculator, enhancing the visual appeal without detracting from the simplicity of the design.

8. Interaction Model & Motion Direction

The landing page will employ an "animated" interaction model. This will include moderate scroll-triggered reveals and hover transitions, ensuring a polished and engaging user experience. The calculator buttons will have spring physics interactions, providing a satisfying tactile response.

9. Non-Functional Requirements

• The application must load within 2 seconds on a standard broadband connection.
• The design should be responsive and function correctly on both desktop and mobile devices.
• The application should be accessible and comply with WCAG 2.1 AA standards.

10. Tech Stack

• Frontend: React for Web
• Backend: Not applicable (single-page application)
• Database: Not applicable (single-page application)

11. Assumptions and Constraints

• The application will be developed as a single-page application with no server-side components.
• The design will prioritize simplicity and ease of use.
• The application will not require user authentication or data storage.

12. Glossary

• Single-page application (SPA): A web application that interacts with the user by dynamically rewriting the current page rather than loading entire new pages from the server.
• WCAG 2.1 AA: Web Content Accessibility Guidelines, a set of recommendations for making web content more accessible, particularly for people with disabilities.
