❓ Frequently Asked Questions

Q: What's the difference between px and % in border-radius?
A: px values are absolute, while % values are relative to the element's dimensions. Use % for creating perfect circles or ovals.

Q: Can I use different units for different corners?
A: Yes! You can mix px, %, em, rem, and other CSS units for individual corners.

Q: What's the maximum border-radius value?
A: Values larger than half the element's dimensions will create a pill shape (for two corners) or circle (for all corners).

Q: Is this tool free?
A: Absolutely — completely free with no registration or limits.
