Design System

When to Apply

• Apply to all user-facing Blade views and shared UI components.
• Apply when creating new components or changing interaction/accessibility behavior.
• Apply both when implementing new UI and when incrementally refactoring legacy Blade screens.
• Do not apply to JSON APIs, console output, or plain-text emails.
• For Markdown/email template styling rules, use the relevant mail/documentation skill instead.

Preconditions

• Existing components are reviewed in /styleguide first.
• Component registry updates are possible in config/styleguide.php.
• Target view is a Blade UI surface, not a backend-only endpoint.

Process

1. Discover Existing Components First

• Check /styleguide before creating a new component.
• Reuse an existing component when it satisfies the same behavior.

2. Build/Update Components with Consistent Structure

• Use Blade components, not raw interactive HTML in page views.
• Distinguish concerns: Blade components define structure/composition; the design system defines visual tokens, states, spacing, and interaction rules.
• Accept $attributes and merge defaults with $attributes->merge([...]).
• Use named slots and @props defaults for composable APIs.

2.1 Legacy Adoption Strategy

• Do not rewrite whole legacy pages at once.
• Replace repeated UI fragments first (buttons, alerts, cards), then migrate larger sections.
• Keep old and new markup interoperable during rollout, but route all new UI through design-system components.

3. Apply Accessibility and Responsive Rules

• Ensure interactive controls meet touch target size (min-h-[44px] and often min-w-[44px]).
• Add visible focus (focus-visible) and disabled/hover states.
• Add aria-label or sr-only text for icon-only controls.
• Build mobile-first and provide card fallback for tabular content on small screens.
• Prefer design tokens over one-off values for spacing, radius, and colors.

4. Register and Verify

• Add new components to config/styleguide.php.
• Add/update styleguide examples so usage is discoverable.

Examples

{{-- Anonymous component with $attributes and @props --}}
@props([
    'variant' => 'primary',
    'size' => 'md',
])

<button
    {{ $attributes->merge(['class' => 'min-h-[44px] rounded-lg px-4 transition ease-in-out duration-150 focus-visible:ring-2 focus-visible:ring-accent-500']) }}
>
    {{ $slot }}
</button>

{{-- Bad -> Good: raw button replaced by design-system component --}}
{{-- Bad: <button class="px-4 py-2 bg-blue-600">Save</button> --}}
<x-button variant="primary">Save</x-button>

{{-- Composable layout with named slots --}}
<x-card>
    <x-slot:header>
        <x-heading level="2">{{ $title }}</x-heading>
    </x-slot:header>
    <x-slot:content>
        {{ $slot }}
    </x-slot:content>
</x-card>

{{-- Visual conventions: shadows, radius, color system --}}
<div class="rounded-lg shadow-sm p-6 transition ease-in-out duration-150">
    <span class="rounded-full bg-green-100 text-green-800 px-3 py-1">Active</span>
</div>

{{-- Icon-only button with ARIA label for screen readers --}}
<button type="button" aria-label="Close dialog" class="min-h-[44px] min-w-[44px] rounded-lg focus-visible:ring-2">
    <x-icon name="x" />
</button>

{{-- Mobile table-to-card fallback mini pattern --}}
<table class="hidden md:table w-full">...</table>
<div class="grid gap-3 md:hidden">
    <x-card>{{-- same row content as stacked key/value pairs --}}</x-card>
</div>

{{-- Prefer token classes instead of arbitrary values --}}
{{-- Good: bg-accent-600 text-on-accent rounded-md --}}
{{-- Avoid: bg-[#1248ff] text-white rounded-[7px] unless token is unavailable --}}

Accessibility Testing

• Keyboard-test interactive flows (Tab/Shift+Tab/Enter/Space/Escape) after UI changes.
• Verify visible focus states in both light/dark themes where applicable.
• Run at least one automated pass (for example Axe/Lighthouse) and fix critical issues.
• Confirm icon-only controls, form fields, and landmark regions have accessible names.

Checklists

• Existing /styleguide component options were checked first.
• New component (if any) is registered in config/styleguide.php.
• Interactive elements include focus, hover/disabled states, and accessibility labels.
• Mobile-first layout and responsive fallbacks are implemented.
• Design tokens were used before introducing one-off values.
• Accessibility checks (keyboard + automated scan) were completed.

Anti-Patterns

• Using raw HTML elements instead of Blade components in page views
• Creating new components without checking the styleguide first
• Forgetting to add new components to config/styleguide.php
• Icon-only buttons without aria-label or sr-only alternative text
• Tables that do not fall back to stacked cards on mobile
• Missing focus-visible rings on interactive elements
• Using raw <h1>-<h6> instead of <x-heading>
