Question 1

What is CSS border-radius?

Accepted Answer

The CSS border-radius property rounds the corners of an element's outer border edge. You can set a single radius for all corners, or specify different values for each corner — top-left, top-right, bottom-right, and bottom-left.

Question 2

What do the four values in border-radius mean?

Accepted Answer

When you provide four values (e.g. border-radius: 10px 20px 30px 40px), they apply clockwise from the top-left: top-left, top-right, bottom-right, bottom-left.

Question 3

What is the shorthand for equal border-radius?

Accepted Answer

If all four corners share the same value, CSS lets you write just one: border-radius: 20px. This generator automatically produces the shortest valid notation — one value, two, three, or four depending on which corners match.

Question 4

How do I use border-radius in Tailwind CSS?

Accepted Answer

Tailwind has built-in utilities like rounded-sm, rounded-lg, and rounded-full. For custom values, use arbitrary syntax: rounded-[30px]. Or apply the generated CSS directly in your global stylesheet or a CSS module.

Question 5

Can I create organic or asymmetric shapes?

Accepted Answer

Yes. Set different radii for each of the four corners to create leaf, petal, arch, wave, and other organic shapes. Use the preset buttons to try common shapes instantly.

Question 6

Is the border-radius generator free?

Accepted Answer

Yes, completely free with no signup required. Copy and use the CSS in any personal or commercial project.
