CSS Border Radius

The border-radius CSS property rounds the corners of an element's outer border edge.

Syntax:
border-radius: [top-left] [top-right] [bottom-right] [bottom-left];
Shorthand Examples:
  • border-radius: 10px; (all corners)
  • border-radius: 10px 20px; (top-left & bottom-right / top-right & bottom-left)
  • border-radius: 10px 20px 30px; (top-left / top-right & bottom-left / bottom-right)
Design Tips
Use subtle radii (4-8px) for professional interfaces
Larger radii work well for cards and containers
Circular elements (50%) create effective avatars
Mix radii for unique organic shapes
Maintain consistency across your design system

How to Use This Tool

The Border Radius Generator is an intuitive tool that helps you create perfect rounded corners for your web design projects. With its visual interface and real-time preview, you can easily experiment with different border radius values and copy the CSS code with a single click.

To begin using the tool, you'll see a preview box on the left side and control sliders on the right. The "All Corners" slider at the top lets you simultaneously adjust all four corners of the element when the "Sync All Corners" option is enabled (which it is by default). This is perfect for creating uniform rounded corners. Simply drag the slider or type a pixel value in the input field to see the changes instantly reflected in the preview box.

For more advanced designs where you want different rounding on each corner, uncheck the "Sync All Corners" option. This unlocks the individual corner controls (Top Left, Top Right, Bottom Right, and Bottom Left), allowing you to create unique shapes with different radii on each side. The preview updates in real-time as you adjust each slider, giving you immediate visual feedback.

Below the controls, you'll find two CSS output fields. The first shows the full border-radius declaration, while the second attempts to provide the most concise version possible using CSS shorthand notation. Click the copy button next to either field to copy the CSS to your clipboard for use in your projects.

To jumpstart your design process, the tool includes example boxes with common radius configurations. Click any example to apply its border radius values to the preview box. The examples range from subtle rounding (5px) to circular shapes (50%) and more creative combinations. Each example briefly shows a checkmark when applied.

In the sidebar, you'll find helpful information about CSS border-radius syntax, including shorthand variations that can make your code more efficient. The design tips section offers practical advice for using border radius effectively in your interfaces, such as using consistent radii across related elements and reserving larger radii for specific components like cards and containers.

Whether you're designing buttons, cards, images, or custom shapes, this Border Radius Generator provides all the tools you need to create perfect rounded corners with pixel-perfect precision. The visual interface eliminates guesswork, and the instant CSS output saves you time in your development workflow.
