The corner-shape property in CSS offers unique design possibilities. This includes designs like vintage tickets with inward-trimmed corners, sci-fi corners, and tags, typically associated with the CSS property corner-shape.

This can be done using CSS @supports like:
@supports not (corner-shape: notch) {
