Accessibility Systems

Document contrast, focus states, keyboard behaviour, motion, labels and readable component rules. This page gives you the structure for planning accessibility systems with practical guidance, browser-based generation and copyable snippets ahead of deeper ElementYard integration.

Contrast controls

Accessibility checklist

  • Use visible keyboard focus styles.
  • Keep normal text at 4.5:1 contrast or stronger.
  • Do not communicate state with colour alone.
  • Pair form inputs with visible labels and helpful errors.

Contrast and focus preview

17.85:1 contrast ratio

Passes WCAG AA for normal text.

Accessible focus CSS
:focus-visible {
  outline: 3px solid #2563eb;
  outline-offset: 3px;
  box-shadow: 0 0 0 6px rgba(37, 99, 235, 0.18);
}

Why it matters

Accessibility shape every component.

Accessibility belongs in the system so every component starts with usable defaults instead of late fixes.

Best practices

Use these rules before turning accessibility systems into tokens or implementation details.

Define contrast expectations for text, states and controls.
Document visible focus and keyboard interaction patterns.
Include form labels, help text and error rules in the system.

Workflow

Keep this practical and repeatable before adding automation.

1. Audit colour contrast and focus states.
2. Document keyboard expectations for interactive components.
3. Define accessible defaults for forms, buttons and navigation.
4. Recheck new components against the system before publishing.

Accessibility FAQ

What are accessibility systems?

Accessibility Systems help teams document practical design decisions for document contrast, focus states, keyboard behaviour, motion, labels and readable component rules.

Does DevKitYard generate accessibility systems today?

Yes. This page includes a browser-based generator for practical starter values and copyable implementation snippets. It is still not pretending to replace a full design-system review.

How do accessibility systems connect to ElementYard?

The system defines the decisions, while ElementYard can eventually apply those decisions to visual component and page-section workflows.
