corner-top-left-shape

An experimental property for the top-left corner shape. It gives designers more control, allowing for beveled or angled corners instead of just rounded ones.

It is documented as part of the CSS Backgrounds and Borders specification. This is an experimental technology. The syntax and behavior are still subject to change.

/* Usage Example */
.hero-card {
  /* Experimental: makes the top-left corner angled */
  corner-top-left-shape: angle;
}

/* Global values */

corner-top-left-shape: initial;
corner-top-left-shape: revert;
corner-top-left-shape: revert-layer;
corner-top-left-shape: unset;
