Frequently Asked Questions

What's the max useful border-radius?

Setting it to 50% on a square element creates a circle. Values above 50% have no additional visual effect.

Can I set different horizontal and vertical radii?

Yes. The CSS border-radius shorthand supports "/" syntax to set elliptical corners (e.g., 10px 20px / 30px 40px).
