Demo: CSS IBM Punch Card Magnetic Follow Button
Source: https://codefronts.com/components/css-buttons/css-ibm-punch-card-magnetic-follow-button/

An 80-column punch card that tilts toward your cursor in real 3D and drifts a few pixels with it: rows of rectangular holes cut by a mask grid, a clipped corner, faded index printing, and a sheen that tracks the light across the card stock.

How this works

The holes are a real mask, not painted rectangles — you can see the background through them, which is the entire point of the object:

-webkit-mask:
  repeating-linear-gradient(90deg, #000 0 .34rem, transparent .34rem .62rem) 0 0/100% 100%,
  linear-gradient(#000,#000);
/* combined with a row mask so only two bands are punched */

The tilt uses rotate3d with the pointer's normalised offsets, plus a small counter-translate so the card seems to lean rather than pivot in place:

transform:
  perspective(760px)
  rotate3d(var(--ty),var(--tx),0,var(--tilt))
  translate3d(calc(var(--tx) * 6px), calc(var(--ty) * -6px), 0);

Because both the tilt and the sheen read the same two variables, the highlight always sits on the raised edge — the detail that makes 3D tilts believable. Keyboard users get the untilted card and a focus ring; prefers-reduced-motion drops the transform entirely.

Make it yours

Hole pitch and size are in the repeating gradient's stops; keep the gap wider than the hole or the card falls apart visually.
Change the number of punched rows by adding row bands to the row mask.
Tilt strength is --tilt-max; 7-10° is convincing.
Swap the printing colour with --print — IBM cards used a pale blue-green; Univac used buff.

Gotchas — read before shipping

rotate3d on a text-bearing element can soften glyph rasterisation; keep angles small and avoid animating during text entry.
Masked holes make the button partially transparent — never place it over busy artwork or the label becomes unreadable.
Tilt must be pointer-only. A keyboard user should never see the card move.
perspective() inside transform applies per element; if you nest tilted elements, set perspective on the parent instead.
Pointer listeners on a tilted element fire against the untransformed box in most engines — don't compute hit maths from the visual position.

Browser support

Chrome	Safari	Firefox	Edge
120+	15.4+	53+	120+

mask shorthand with multiple layers: Chrome 120 / Safari 15.4 (prefixed earlier) / Firefox 53. Without mask support the holes are not punched but the card, tilt and sheen all work.
