A clearer picture,
for everyone.

Each comparison includes readable values, property labels, a text explanation, and a description of the visual model. Colour is reinforced with labels and marked spans.

Keyboard

Tab moves through controls. Enter submits a search; Up and Down select suggestions; Escape closes them. Property and world selectors are buttons. Scale sliders support arrow keys, Home and End. Scale It also provides labelled minus and plus buttons, so dragging is never required. Quiz answers are semantic buttons and feedback is announced without automatic advance. A skip link leads straight to the main content.

Motion and small screens

Motion is optional and respects reduced-motion settings. The core numbers are HTML text. Diagrams and game art retain physical proportions as the viewport changes. Browser zoom and print styles are supported.

Without JavaScript

Canonical encyclopedia destinations and the Understanding Size & Scale lesson contain substantive static HTML. Game rules and setup remain readable, but seeded selection, scoring and interactive controls require JavaScript. This describes the implemented features, not an independent accessibility certification.
