Ledger Scenario comparison matrix

Compares assumptions and outcomes across several possible futures for dense comparable records with row actions; it is designed to support scanning, comparison, responsive reflow, and keyboard action. Editing an assumption updates dependent cells and highlights material differences. The tables and records variant is specialized for data relationships must remain meaningful on narrow screens. Users can support scanning, comparison, responsive reflow, and keyboard action while understanding the current state, available choices, and resulting consequence.

Implementation field notes

Use ledger scenario comparison matrix confidently.

The preview and source are only the starting point. Use these notes to decide where the component fits, preserve its accessibility contract, and verify the adapted result.

Good fit for

  • Tables and records
  • Accounts
  • Compares assumptions and outcomes across several possible futures for dense comparable records with row actions

This tables and records pattern works best when its purpose is clear in the surrounding page hierarchy.

Accessibility contract

  • The primary purpose and current state remain available as text and do not depend on color, motion, pointer position, or visual geometry.
  • Every interaction has keyboard equivalence, visible focus, predictable Escape behavior where applicable, and appropriately scoped status announcements.
  • Reduced-motion, 200% zoom, long-content, narrow-container, and forced-color behavior are part of the implementation acceptance criteria.

Integration plan

  1. Copy the standalone HTML and scoped CSS into an isolated page.
  2. Adapt primary signal, secondary signal, layered surface, primary text through the Inspector.
  3. Connect the defensive JavaScript, then test every control with a keyboard.
  4. Review the result at 375, 768, 1024, and 1440 pixels before shipping.
