border-end-end-radius

The border-end-end-radius CSS property defines a logical border radius on an element, which maps to a physical border radius that depends on the element's writing-mode, direction, and text-orientation. This is useful when building styles to work regardless of the text orientation and writing mode.

/* <length> values */
/* With one value the corner will be a circle */
border-end-end-radius: 10px;
border-end-end-radius: 1em;

/* With two values the corner will be an ellipse */
border-end-end-radius: 1em 2em;

/* Global values */
border-end-end-radius: inherit;
border-end-end-radius: initial;
border-end-end-radius: revert;
border-end-end-radius: unset;

This property affects the corner between the block-end and the inline-end sides of the element. For instance, in a horizontal-tb writing mode with ltr direction, it corresponds to the border-bottom-right-radius property.
