Technical Specification: Responsive Golden Ratio UI Calculator

Core Objective

To provide designers and developers with an instantaneous, precise calculation engine for applying the 'Golden Ratio' (1.618) to web layout elements, ensuring proportional harmony in digital interfaces.

User Interface Design

  • Theme: Clean, minimalist, 'Design-Tool' aesthetic. Dark mode and Light mode toggles.
  • Colors: Slate gray backgrounds (#1e1e1e), white typography (#ffffff) for high contrast, and a distinct primary accent color (e.g., #3b82f6) for calculated result highlights.
  • Layout:
    • Sidebar: Navigation and presets (e.g., 'Container Width', 'Sidebar Width', 'Typography Hierarchy').
    • Main Area: Primary calculator input field, dynamic result panels, and a visual representation pane.

Functional Requirements

  1. Dynamic Input Engine:

    • A primary field for users to enter a base dimension (e.g., width or font size).
    • A toggle switch to multiply or divide by the Golden Ratio (1.618).
    • Real-time output display showing the result rounded to the nearest pixel or decimal.
  2. Visual Previewer:

    • A side-by-side canvas showing two rectangles based on the calculated inputs.
    • Visual overlays demonstrating how the 1.618 ratio affects layout balance.
  3. Typography Scaling Module:

    • A dedicated tab where users input a 'Base Font Size'.
    • The application automatically generates a modular scale (Heading 1 to Heading 6) based on the golden ratio.
  4. CSS Export/Copy:

    • 'Copy to Clipboard' buttons next to all outputs for immediate pasting into CSS files.
  5. Responsive Grid Helper:

    • Allows users to input a screen width (e.g., 1440px) to calculate the golden-ratio split for main content area vs. sidebar width.

Interactive Features

  • Live Feedback: Instant recalculation as numbers are typed—no 'Calculate' button required.
  • History Log: An optional panel showing the last 10 calculations, allowing users to compare different scale iterations.
  • Unit Converter: Auto-converts pixels to REMs (using a user-defined base font size, e.g., 16px) for modern web standards.

Accessibility Standards

  • Keyboard navigable for all inputs.
  • Screen-reader friendly labels on all buttons.
  • High contrast ratios for all UI elements (WCAG AA compliant).
