➡️ CSS border-bottom-right-radius: Styling the Bottom-Right Corner with Rounded Elegance

Rounded corners add softness and visual appeal to web elements. While border-radius affects all corners, border-bottom-right-radius targets the bottom-right corner exclusively, giving you fine control to craft distinctive shapes and styles.

🧾 What is border-bottom-right-radius?

The border-bottom-right-radius property sets the curvature radius of the bottom-right corner of an element’s border box. It defines how rounded or sharp that corner appears.

🧬 Syntax

selector {
  border-bottom-right-radius: <length> | <percentage>;
}
  • <length>: fixed units like px, em, rem (e.g., 10px, 1.5em)
  • <percentage>: relative to the element’s dimensions (e.g., 50%)

You can provide either one or two values:

  • One value applies the same radius horizontally and vertically.
  • Two values specify horizontal radius and vertical radius separately, creating elliptical curves.

🎯 Examples

1. Simple rounded bottom-right corner

div {
  border-bottom-right-radius: 15px;
}

Rounds the bottom-right corner with a 15px radius.

2. Elliptical radius with two values

button {
  border-bottom-right-radius: 20px 10px;
}

Creates an elliptical curve with 20px horizontal and 10px vertical radii.

3. Using percentage for responsive curves

.card {
  border-bottom-right-radius: 50%;
}

Generates a large, smooth quarter-circle curve adapting to the element’s size.

🔍 How It Works

  • The radius defines an ellipse that clips the corner.
  • Horizontal radius is relative to the element’s width; vertical radius relative to height.
  • Large radius values create more pronounced curves.
  • Works in combination with other corner radius properties (border-top-left-radius, border-bottom-left-radius, border-top-right-radius) for complex shapes.

🛠️ Practical Uses

  • Buttons and UI controls: Rounded bottom-right corners for unique button shapes.
  • Cards and panels: Softens the bottom-right edge for a modern look.
  • Speech bubbles: Curved tails using only bottom-right radius.
  • Decorative effects: Combine different corner radii for dynamic design.

✅ Best Practices

  • Match radius values to your overall design language.
  • Avoid very large radii on small elements to prevent awkward shapes.
  • Test on multiple devices and browsers — well-supported across all modern browsers.
  • Combine with box-shadow and background for enhanced visual depth.

🔚 Conclusion

The CSS border-bottom-right-radius property offers elegant control to round the bottom-right corner of elements, helping you create polished, professional, and visually pleasing designs. It’s a simple but powerful way to customize your UI beyond uniform corner rounding.
