Common questions
How does the 8-value border-radius syntax work?
The shorthand 'border-radius: TL TR BR BL / TL TR BR BL' sets horizontal radii before the slash and vertical radii after. This creates elliptical corners for organic, blob-like shapes instead of simple circular corners.
How do I make a perfect circle with border-radius?
Set border-radius to 50% on a square element (equal width and height). For a pill or capsule shape, set border-radius to a value equal to or greater than half the element's height on a rectangular element.
