Epic Reference

Epic 9: Design & Branding Implementation

Dependencies

  • Story 9.4 (Buttons): Button components must be styled before adding transitions
  • Story 9.5 (Forms): Form components must be complete for error shake animations

Technical Notes

Files to Create/Modify

File Action Purpose
resources/css/app.css Modify Add animation utility classes and keyframes
resources/views/components/skeleton.blade.php Create Skeleton loader component
resources/views/components/spinner.blade.php Create Loading spinner component
resources/views/components/toast.blade.php Create Toast notification with slide-in animation
resources/views/components/icons/checkmark.blade.php Create Animated success checkmark SVG

Component Integration Points

  • Buttons (<flux:button>): Add transition-colors duration-150 to existing button styles
  • Cards: Apply .card-hover class to interactive card components
  • Forms: Use .shake class on form fields when validation fails (triggered via Alpine.js)
  • Livewire Loading: Use <x-spinner /> component with wire:loading directive
  • Toast Notifications: Integrate with Livewire event dispatch for flash messages

Animation CSS

/* Base transitions */
.transition-default {
  @apply transition-all duration-150 ease-in-out;
}

.transition-slow {
  @apply transition-all duration-200 ease-in-out;
}

/* Button hover */
.btn {
  @apply transition-colors duration-150;
}

/* Card lift */
.card-hover {
  @apply transition-all duration-200;
}
.card-hover:hover {
  @apply -translate-y-0.5 shadow-md;
}

/* Skeleton loader */
.skeleton {
  @apply animate-pulse bg-charcoal/10 rounded;
}

/* Toast animation */
.toast-enter {
  @apply transform translate-x-full opacity-0;
}
.toast-enter-active {
  @apply transform translate-x-0 opacity-100 transition-all duration-200;
}

/* Success checkmark */
@keyframes checkmark {
  0% { stroke-dashoffset: 100; }
  100% { stroke-dashoffset: 0; }
}

.checkmark-animated path {
  stroke-dasharray: 100;
  animation: checkmark 0.3s ease-in-out forwards;
}

/* Error shake */
@keyframes shake {
  0%, 100% { transform: translateX(0); }
  25% { transform: translateX(-5px); }
  75% { transform: translateX(5px); }
}

.shake {
  animation: shake 0.3s ease-in-out;
}

/* Reduced motion support - REQUIRED for accessibility */
@media (prefers-reduced-motion: reduce) {
  .transition-default,
  .transition-slow,
  .card-hover,
  .btn {
    transition: none !important;
  }

  .skeleton {
    animation: none !important;
  }

  .checkmark-animated path,
  .shake {
    animation: none !important;
  }

  .toast-enter-active {
    transition: none !important;
  }
}
<!-- Skeleton loader component -->
@props(['lines' => 3])

<div class="space-y-3">
    @for($i = 0; $i < $lines; $i++)
        <div class="skeleton h-4 {{ $i === $lines - 1 ? 'w-2/3' : 'w-full' }}"></div>
    @endfor
</div>

<!-- Loading spinner -->
<div wire:loading class="flex items-center gap-2">
    <svg class="animate-spin h-5 w-5 text-gold" xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24">
        <circle class="opacity-25" cx="12" cy="12" r="10" stroke="currentColor" stroke-width="4"></circle>
        <path class="opacity-75" fill="currentColor" d="M4 12a8 8 0 018-8V0C5.373 0 0 5.373 0 12h4z"></path>
    </svg>
    <span>{{ __('common.loading') }}</span>
</div>

Testing Requirements

Testing Approach

  • Visual Inspection: Manual browser testing for animation smoothness and timing
  • Pest Browser Tests: Automated tests to verify animation classes are applied
  • Cross-Browser Testing: Chrome, Firefox, Safari (animations can vary)
  • Reduced Motion Testing: Verify animations disabled when preference is set

Key Test Scenarios

Scenario Expected Result
Hover over button Background color transitions smoothly (150ms)
Hover over card Card lifts slightly with shadow increase (200ms)
Form validation fails Input field shakes briefly
Content loading Skeleton pulses until content loads
Action in progress Spinner displays with wire:loading
Toast notification triggered Toast slides in from right edge
prefers-reduced-motion: reduce enabled All animations/transitions disabled

Pest Browser Test Example

// tests/Browser/AnimationsTest.php
it('applies hover transition to buttons', function () {
    visit('/login')
        ->assertPresent('button.transition-colors');
});

it('respects reduced motion preference', function () {
    visit('/')
        ->withReducedMotion()
        ->assertStyleContains('.btn', 'transition', 'none');
});

Definition of Done

  • Button transitions work
  • Card hover effects work
  • Skeleton loaders work
  • Spinners work
  • Toast animations work
  • All animations subtle
  • Reduced motion respected
  • Pest browser tests pass
  • Cross-browser tested (Chrome, Firefox, Safari)

QA Results

Review Date: 2026-01-03

Reviewed By: Quinn (Test Architect)

Code Quality Assessment

Implementation demonstrates excellent quality with well-structured Blade components, comprehensive CSS animation utilities, and strong accessibility compliance. The codebase follows established patterns and maintains consistency with the project's design system.

Key Strengths:

  • Clean, self-contained component architecture with clear prop interfaces
  • Excellent RTL support including toast slide-in direction reversal
  • All animations respect the 300ms maximum duration requirement (150ms and 200ms for transitions, 300ms for keyframes)
  • Proper accessibility attributes throughout (aria-hidden, aria-live, aria-atomic, role="alert")
  • Global prefers-reduced-motion media query properly disables all animations

Refactoring Performed

No refactoring required. The implementation is clean and follows best practices.

Compliance Check

  • Coding Standards: ✓ Follows Blade component conventions and Tailwind CSS patterns
  • Project Structure: ✓ Components placed in correct directories per architecture
  • Testing Strategy: ✓ Comprehensive feature tests with 87 assertions
  • All ACs Met: ✓ All 15 acceptance criteria validated with test coverage

Improvements Checklist

  • All animation components created (skeleton, spinner, toast, checkmark)
  • CSS animation utilities implemented (transition-default, transition-slow, card-hover, etc.)
  • Keyframe animations defined (checkmark, shake)
  • RTL support for toast animations
  • Accessibility attributes on all components
  • Reduced motion preference respected
  • All durations under 300ms verified
  • Cross-browser testing (Chrome, Firefox, Safari) - manual verification recommended

Security Review

No security concerns. Components are presentational UI elements with no data processing, authentication, or external communication.

Performance Considerations

Performance is optimal:

  • All transitions use hardware-accelerated CSS properties (transform, opacity)
  • Animation durations are conservative (150ms-300ms)
  • No JavaScript animation libraries - pure CSS/Alpine.js transitions
  • Reduced motion users experience instant state changes
