CSS border radius is used to round the corners of the outer border edges of an element. This property can contain one, two, three, or four values. The border-radius property is used to set the border-radius. This property is not applicable to the table elements when border-collapse is collapsing.
Try It:
Currently Active Property:
border-radius: 10px;
Syntax:
border-radius: 1-4 length|% / 1-4 length|%|initial|inherit;
Property Values:
- length: It represents the shape of the corners & the default value is 0.
- percentage(%): It represents the shape of the corners in %.
- initial: It is used to set an element’s CSS property to its default value.
- inherit: It is used to inherit a property to an element from its parent element property value.
Shorthands:
- Apply Radius value to all four corners:
border-radius: value; - Apply value1 to top-left and bottom-right corners and value2 to top-right and bottom-left corners:
border-radius: value1 value2; - Apply value1 to top-left corner, value2 to top-right and bottom-left corners and value3 to bottom-right corner:
border-radius: value1 value2 value3; - Apply value1 to top-left corner, value2 to top-right corner , value3 to bottom-right corner and value4 to bottom-left corner:
border-radius: value1 value2 value3 value4;The 4 values for each radius can be specified in the following order as top-left, top-right, bottom-right, bottom-left. If the bottom-left is removed then it will be the same as the top-right. Similarly, If the bottom-right & top-right will be removed then it will be the same as the top-left & the top-left respectively.
CSS Border Radius Examples
border-radius: 35px; sets the border-radius of each corner. It is the combination of four properties: border-top-left-radius, border-top-right-radius, border-bottom-left-radius, and border-bottom-right-radius. It sets all corners to the same value.
Example 1: This example illustrates the border-radius property whose value is specified by the single value.
<!DOCTYPE html>
<html>
<head>
<title>Rounded Corners</title>
<style>
.GFG {
border-radius: 35px;
background: #009900;
padding: 30px;
text-align: center;
width: 300px;
height: 120px;
}
</style>
</head>
<body>
<div class="GFG">
<h2>GeeksforGeeks</h2>
<p>border-radius: 35px;</p>
</div>
</body>
</html>
Output:
border-radius: 20px 40px; sets first value as top-left and bottom right corner and second value as top right and bottom left corners.
Example 2: This example illustrates the border-radius property whose value is specified by the double values.

</div>
</body>
</html>
Output:
