Ribbon Tag Close Button

A corner-ribbon dismiss for cards, coupons and promo tiles: the close control IS a folded ribbon clipped diagonally across the card's top-right corner with clip-path:polygon(), complete with a darker fold-under triangle that sells the wrap. Hover slides the ribbon outward a notch; the whole diagonal band is the hit area.

## JavaScript
```js
/* No JavaScript — the button IS a 45°-rotated band clipped by the card; the × counter-rotates to stay upright. */
```

How this works

The ribbon is the button itself: a wide bar rotated 45° and positioned so it crosses the corner, clipped by the CARD's overflow:hidden — no polygon math on the band. The fold-under is a small triangle (clip-path:polygon()) in a darker shade tucked where the ribbon exits the card edge, the classic double-layer that makes it read as wrapped fabric rather than a stripe.

Because the button is rotated, its × counter-rotates -45deg to stay upright. The diagonal band yields a generous skewed hit area far past 44px on its long axis. Hover translates the ribbon 3px along its own diagonal (transform composes translate before the rotation), like a tag being tugged.

Make it yours

  • Ribbon hue via --ribbon; the fold auto-darkens with color-mix.
  • Corner: mirror to top-left by flipping inset-inline-end and the rotation sign.
  • Add 'CLOSE' text before the × (letter-spaced small caps) for promo banners.
  • Widen the band (34px → 44px) when it doubles as a 'dismiss offer' label.

Gotchas — read before shipping

  • The card must clip (overflow:hidden) — an unclipped ribbon shows its raw rectangular ends.
  • Counter-rotate the glyph or your × renders as a + (rotated 45° it IS a plus).
  • Test the focus ring: outlines follow the rotated box, so use outline-offset to keep it readable across the diagonal.

clip-path:polygon() and rotated buttons — all long-settled; color-mix darkens the fold.
