Frequently Asked Questions

What is CSS border-radius?

CSS border-radius is a property that allows you to create rounded corners on HTML elements. Instead of sharp 90-degree corners, you can make corners curved with different radius values. It's commonly used for modern UI design on buttons, cards, containers, and images to create a softer, more polished look.

Can I set different radius values for each corner?

Yes! This generator lets you control each corner independently. You can set different values for top-left, top-right, bottom-right, and bottom-left corners. This is useful for creating unique shapes like tabs, speech bubbles, or asymmetrical design elements.

What units can I use for border-radius?

You can use px (pixels), em, rem, or % (percentage). Pixels give you exact control, em/rem scale with font size, and percentages create responsive corners that scale with element size. For perfect circles, use 50% border-radius on square elements.

How do I make a perfect circle with border-radius?

To create a perfect circle, set border-radius to 50% on a square element (same width and height). For example, a 100px × 100px div with border-radius: 50% becomes a perfect circle. This works because 50% of the width/height creates a radius that curves all the way around.

Does border-radius work on all elements?

Border-radius works on most HTML elements including divs, buttons, images, inputs, and containers. However, it may not work as expected on some inline elements. For best results, use it on block or inline-block elements. Images need overflow:hidden if you want the content to follow the rounded shape.

Yes, completely free with no signup required. All processing happens in your browser - no data is sent to servers. Generate and copy as much CSS border-radius code as you need.
