How the 8-Point CSS Border Radius Syntax Works

CSS border-radius accepts up to eight values separated by a slash: border-radius: 60% 40% 70% 30% / 40% 60% 30% 70%;. The numbers preceding the slash specify the horizontal radii, while the numbers after define the vertical radii. This asymmetry creates natural, organic blob curves popular in modern web design.
