Rounded Corners in CSS

Rounded corners in css add a touch of elegance to web design by softening the edges of elements. In CSS, you can achieve rounded corners using different techniques and properties.

Basics

Border-Radius Property

The 'border-radius' property is the fundamental CSS property for creating rounded corners.

				
					/* Apply rounded corners to an element */
.rounded-box {
  border-radius: 10px; /* All corners have a radius of 10px */
}

Individual Corner Radii

Specify different radii for each corner using the 'border-top-left-radius', 'border-top-right-radius', 'border-bottom-left-radius', and 'border-bottom-right-radius' properties.

				
					/* Apply different radii to each corner */
.custom-rounded-box {
  border-top-left-radius: 20px;
  border-top-right-radius: 10px;
  border-bottom-left-radius: 15px;
  border-bottom-right-radius: 25px;
}

Intermediate Usage

Ellipse-Shaped Corners

Use two values in the 'border-radius' property to create elliptical or oval-shaped corners.

				
					/* Create elliptical-shaped corners */
.ellipse-box {
  border-radius: 20px 10px; /* Horizontal radius: 20px, Vertical radius: 10px */
}

Percentage-Based Radius

Utilize percentage values for relative corner radii based on the element’s size.

				
					/* Set rounded corners using percentage values */
.percent-rounded-box {
  border-radius: 10%; /* All corners have a radius of 10% of the box size */
}

Advanced Techniques

Transparent Borders for Corner Gaps

Use transparent borders to create gaps between rounded corners.

				
					/* Create gaps between rounded corners */
.gapped-box {
  border: 10px solid transparent;
  border-radius: 20px;
}

Clip-Path for Custom Shapes

Employ the 'clip-path' property for more complex and custom shapes.

				
					/* Create a custom-shaped element with clip-path */
.custom-shape {
  clip-path: polygon(0 0, 100% 0, 100% 80%, 50% 100%, 0 80%);
}

Rounded corners in CSS offer a simple yet effective way to enhance the visual appeal of your web designs. The 'border-radius' property, along with its variations, provides the flexibility to create rounded corners for various elements. Happy Coding! ❤️
