border-bottom-right-radius

The border-bottom-right-radius CSS property sets the rounding of the bottom-right corner of the element.

/* The corner is a circle */
/* border-bottom-right-radius: radius */
border-bottom-right-radius: 3px;

/* Percentage values */
border-bottom-right-radius: 20%; /* corner of a circle if box is a square or else corner of a rectangle */
border-bottom-right-radius: 20% 20%; /* same as above */ /* 20% of horizontal(width) and vertical(height) */
border-bottom-right-radius: 20% 10%; /* 20% of horizontal(width) and 10% of vertical(height) */

/*The corner is an ellipsis */
/* border-bottom-right-radius: horizontal vertical */
border-bottom-right-radius: 0.5em 1em;

border-bottom-right-radius: inherit;

The rounding can be a circle or an ellipse, or if one of the value is 0 no rounding is done and the corner is square.

A background, being an image or a color, is clipped at the border, even a rounded one; the exact location of the clipping is defined by the value of the background-clip property.

备注： If the value of this property is not set in a border-radius shorthand property that is applied to the element after the border-bottom-right-radius CSS property, the value of this property is then reset to its initial value by the shorthand property.

Syntax

With one value:

  • the value is a <length> or a <percentage> denoting the radius of the circle to use for the border in that corner.

With two values:

  • the first value is a <length> or a <percentage> denoting the horizontal semi-major axis of the ellipsis to use for the border in that corner.
  • the second value is a <percentage> denoting the vertical semi-major axis of the ellipsis to use for the border in that corner.

Values

<length-percentage>

Denotes the size of the circle radius or the semi-major and semi-minor axes of the ellipsis. As absolute length it can be expressed in any unit allowed by the CSS <length> data type. Percentages for the horizontal axis refer to the width of the box, percentages for the vertical axis refer to the height of the box. Negative values are invalid.

Formal syntax

border-bottom-right-radius = 
  <length-percentage [0,∞]>{1,2}  

<length-percentage> = 
  <length>      |
  <percentage>
