How does 8-point border-radius work in CSS?
The slash syntax (e.g. border-radius: 30% 70% 70% 30% / 30% 30% 70% 70%) sets horizontal radii before the slash and vertical radii after the slash, creating asymmetrical curves.
Is this supported in all browsers?
Yes, 8-point border-radius is part of the CSS Backgrounds and Borders Level 3 standard and is universally supported across all modern browsers.
