CSS3 border-bottom-right-radius Property

Topic: CSS3 Properties ReferencePrev|Next


The border-bottom-right-radius CSS property sets the rounded shape for the 'bottom-right' corner of an element border box.

The following table summarizes the usages context and the version history of this property.

Default value: 0
Applies to: All elements
Inherited: No
Animatable: Yes. See animatable properties.
Version: New in CSS3

Note: The border-bottom-right-radius property causes the element's background to be rounded even if no borders have been defined or its value is set to none.


The syntax of the property is given with:

[ length | percentage ]1 or 2 values | initial | inherit

This shorthand notation can take one, or two whitespace separated values.

  • The optional second length values define the vertical radii for the top-right corner and the corner shape is thus a quarter ellipse.
  • If the second length is omitted, or it is equal to the first — the corner shape is a quarter circle. If either length is zero, the corner is square, not rounded.

The example below shows the border-bottom-right-radius property in action.

div {
    border: 2px solid #f08080;
    border-bottom-right-radius: 20px;
