Walkthrough

Navigation button styling in the media component has been refactored from absolute-positioned translucent pills to group-based containers with transparent backgrounds. A wrapper span now applies hover effects via group-hover to extend the interactive area around each chevron icon.

Changes

Cohort / File(s)	Summary
Navigation Button Styling frontend/src/components/Media/NavigationButtons.tsx	Changed button styling from absolute-positioned, translucent black rounded pills to group-based transparent containers. Added span wrapper around each icon with group-hover effects (background fade and shadow). Adjusted Tailwind classes for positioning and hover behavior to extend hover area around navigation arrows.

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~8 minutes

• Verify that group-hover implementation correctly extends the hover activation area as specified in the feature request (~5 rem hotspot)
• Confirm visual appearance (background fade and shadow on hover) renders correctly in both light and dark modes
• Check that DOM structure changes don't impact accessibility or keyboard navigation

Poem

🐰 A hop and a click, what joy to behold,
Hovering arrows with room to extol!
No pixel precision, just hover nearby,
The buttons expand—users laugh, never sigh! 🎯

15-33: Consider extracting shared button structure.

Both navigation buttons share nearly identical markup and styling, differing only in positioning, icon, and aria-label. Extracting a shared component or helper function would improve maintainability.

const NavigationButton: React.FC<{
  direction: 'previous' | 'next';
  onClick: () => void;
}> = ({ direction, onClick }) => {
  const isPrevious = direction === 'previous';
  const Icon = isPrevious ? ChevronLeft : ChevronRight;
  
  return (
    <button
      onClick={onClick}
      className={`group absolute inset-y-0 ${isPrevious ? 'left-0' : 'right-0'} z-30 flex w-20 cursor-pointer items-center justify-center bg-transparent text-white`}
      aria-label={`${isPrevious ? 'Previous' : 'Next'} image`}
    >
      <span className="flex items-center justify-center rounded-full p-3 backdrop-blur-md transition-all duration-200 group-hover:bg-black/80 group-hover:shadow-lg">
        <Icon className="h-6 w-6" />
      </span>
    </button>
  );
};

15-23: Hover hotspot extension correctly implemented.

The button now spans 5rem (w-20) in width and full height (inset-y-0), matching the requirement from issue #658. The group utility with transparent background correctly extends the hover activation area, while the inner span provides visual feedback only when hovering anywhere within the button.

---

25-33: Next button implementation looks good.

The implementation mirrors the Previous button correctly with appropriate positioning (right-0 vs left-0) and icon direction.

---

15-33: Verify test coverage for hover interaction.

The PR objectives note that unit tests are not yet added or passing. Please ensure the extended hover hotspot is covered by tests, particularly:

• Hover activation within the 5rem area
• Click handling across the extended area
• Visual feedback behavior
