Hanging Ribbon Bookmark

A cloth bookmark that drops over the top edge of the card when you save the article — it falls, overshoots, and settles with a two-beat pendulum swing, exactly like a real ribbon marker in a book. One toggle button drives it, the state is aria-pressed (not a class), and the whole animation is transform-origin: top center plus five keyframes.

Demo: Hanging Ribbon Bookmark
Source: https://codefronts.com/snippets/css-ribbons/hanging-ribbon-bookmark/

A cloth bookmark that drops over the top edge of the card when you save the article — it falls, overshoots, and settles with a two-beat pendulum swing, exactly like a real ribbon marker in a book. One toggle button drives it, the state is aria-pressed (not a class), and the whole animation is transform-origin: top center plus five keyframes.

How this works

The ribbon lives above the card and hangs down over its top edge, so the card must not clip and the ribbon must sit at a negative block offset:

.bookmark {
  position: absolute;
  inset-block-start: -16px;         /* rises above the card's top edge */
  inset-inline-end: 30px;
  block-size: 0;                    /* collapsed when unsaved */
  transform-origin: top center;     /* the pin it swings from */
  transition: block-size .5s cubic-bezier(.16,1,.3,1);
}
[aria-pressed="true"] ~ .bookmark {
  block-size: var(--drop);
  animation: swing .95s cubic-bezier(.34,1.2,.64,1) .12s;
}

Animating block-size from 0 gives the "unrolling" drop; the swing is a separate rotation animation on the same element, and because transform-origin is the top edge, it pivots from where a real ribbon would be stitched:

@keyframes swing {
  0%   { rotate: 0deg }
  35%  { rotate: 5deg }
  60%  { rotate: -3.2deg }
  80%  { rotate: 1.4deg }
  100% { rotate: 0deg }
}

Decaying amplitude across four beats (5 → 3.2 → 1.4 → 0) is what reads as physics. Equal-amplitude swings read as a broken loop.

The tail is the same notched clip-path as demo 10, and the fold where the ribbon wraps the card's top edge is a darker pseudo-element with filter: brightness(.72) — one declaration instead of a second hand-picked colour, so re-theming stays a single-token change.

The control is a <button aria-pressed>. That is the correct pattern for a two-state toggle: the accessible name stays "Save article" while the state changes, so screen-reader users hear "Save article, toggle button, pressed" rather than a label that mutates under them.

Make it yours

  • Change the hang length with --rib-11-drop; anything from 60px (a discreet tab) to 140px (a proper bookmark) works without touching the keyframes.
  • Add a fold shadow that deepens as it drops by transitioning the pseudo-element's opacity alongside the height.
  • Multiple ribbons per card (saved + read later) — offset each by inset-inline-end: calc(26px + var(--i) * 34px) and stagger the swing delay.
  • Swap the notch for a straight hem or a rounded end by editing the single clip-path; nothing else in the component depends on the tail shape.

Gotchas — read before shipping

  • A hanging bookmark needs an unclipped card. In a grid with overflow: hidden for image rounding, move the clip onto the image, not the card.
  • Never toggle a class and leave the button's accessible state unchanged. aria-pressed is the state; CSS should read it with [aria-pressed="true"] so the visual and the semantic can never drift apart.
  • Height animations are layout-affecting and can jank in a long list. This one is on an absolutely-positioned element, so it never reflows siblings — keep it that way.
  • Don't restart the swing on every re-render; retrigger it deliberately by removing and re-adding the animation (a forced reflow read of offsetWidth) only when the state actually changes.
  • Under prefers-reduced-motion the ribbon must still appear — this demo snaps it to full height with no swing rather than hiding the feature.

Floor set by oklch(), color-mix(), backdrop-filter, text-wrap as this demo is written. The core technique itself goes back further — Chrome 104+.

Individual rotate property needs Chrome 104 / Safari 14.1 / Firefox 72; older engines can use transform: rotate() with identical results. clip-path and logical properties are universal.
