How this works

The card border transitions between two states: a normal rounded rectangle at rest, and a morphed shape on hover — either heavier corner radius, wavy edges via border-image, or a different border style entirely (dashed, dotted).

The transition animates border-radius, border-width, or border-color individually. Different border properties transition at different rates so the effect reads as a sculpted morph rather than a uniform grow.

An accompanying box-shadow shift adds visual weight during the morph — the card doesn't just change border, it changes stature.

Make it yours

  • Change morph type — swap corner-radius values (12px to 32px) for a smooth soften, or corner-radius shortcuts (12px 4px 24px 4px) for asymmetric squish.
  • Rebrand the border colour from --border-rest, --border-hover on .card-22.
  • Tune morph timing — 300ms for snappy, 700ms for organic.
  • Add a subtle rotation to the card during morph (rotate(1deg)) for a hand-drawn feel.
  • Change border-style on hover (solid to double, or dashed to solid) for a more explicit shift.

Gotchas — read before shipping

  • border-radius is fully animatable but border-image is not — use pseudo-elements for image-based border morphs.
  • Test the morph against the card's actual content — heavy corner-radius on hover can make CTA buttons feel pinched.
  • Under prefers-reduced-motion, shorten the transition to 100ms so the morph happens instantly.
  • For dark cards, ensure the morphed border colour retains 3:1 contrast against the surrounding page.
  • Very high corner-radius values (over ~50% of the card's smaller dimension) will produce ellipse-like shapes — usually intentional, but test.

Animating border-radius, border-width, and border-color is universally supported. border-image animation is not supported cross-browser.
