What is CSS Border Radius?
The border-radius CSS property rounds the corners of an element's outer border edge. You can set a single radius to make circular corners, or two radii to make elliptical corners. It works seamlessly even when the element has no border defined, directly rounding the element's background and clipped content.
How to Use Individual Corner Radii
Using multiple values for border-radius allows you to create highly stylized elements such as message bubbles, custom buttons, and complex geometric shapes. You can define the radius of each corner independently:
- 1 value:
border-radius: 10px;applies to all four corners. - 2 values:
border-radius: 10px 50px;applies to top-left & bottom-right (first value), and top-right & bottom-left (second value). - 3 values:
border-radius: 10px 50px 20px;applies to top-left, top-right & bottom-left, and bottom-right. - 4 values:
border-radius: 10px 50px 20px 5px;applies in clockwise order starting from top-left: top-left, top-right, bottom-right, bottom-left.
Browser Compatibility
The border-radius property is universally supported in all modern browsers, including Chrome, Firefox, Safari, and Edge. Generating standard CSS with this tool ensures cross-browser compatibility without needing vendor prefixes like -webkit- or -moz-.
