Engineering Specification

Component Architecture & Rationale

The Image Accordions component displays high-resolution imagery, case studies, or portfolio items in an elegant horizontal strip. When a user hovers or taps any panel, it expands smoothly from flex: 1 to flex: 4, gracefully shrinking adjacent panels and unveiling detailed titles, tags, and call-to-action buttons.

Leverages modern CSS flexbox flex-grow transitions (transition: flex 0.5s cubic-bezier(0.16, 1, 0.3, 1)) coupled with background image cover scaling. Automatically transitions to a vertical stacked layout on mobile viewports for effortless touch scrolling.

Key Technical Features

  • ✓Silky smooth CSS flex-grow transition timing without layout flicker
  • ✓Dynamic metadata overlays (tags, headlines, description text)
  • ✓Responsive design switching from horizontal panels to vertical cards on mobile
  • ✓Full keyboard arrow-key navigation with Enter/Space panel expansion
  • ✓High-performance image loading with object-fit: cover
