🙋 Introduction

The border-radius property in CSS is used to create rounded corners on elements.

This property allows you to define how much rounding you want on each corner, which can be applied to all corners uniformly or individually. Rounded corners can add a softer, more modern look to your elements, making your design more visually appealing.

💡 Syntax

The syntax for the border-radius property is simple and flexible. You can specify one, two, three, or four values to define the rounding of the corners.

Syntax

Copied

element {
  border-radius: value;
}

One value: Applies to all four corners.
Two values: The first value applies to the top-left and bottom-right corners, and the second value applies to the top-right and bottom-left corners.
Three values: The first value applies to the top-left corner, the second to the top-right and bottom-left corners, and the third to the bottom-right corner.
Four values: Each value applies to a different corner in the order: top-left, top-right, bottom-right, and bottom-left.

🎛️ Default Value

The default value of the border-radius property is 0, which means that the element has sharp, right-angled corners.

🏠 Property Values

Value	Description
Length	You can specify a length value (e.g., 10px, 5em) to determine the radius.
Percentage	You can use a percentage (e.g., 50%) to create rounded corners relative to the element's size.
Shorthand	The `border-radius` property can be specified as a single value, two values, three values, or four values to individually control the radius of each corner.

📄 Example

In this example, we'll create a box with rounded corners using the border-radius property.
