The borderTopRightRadius property defines the radius of the border for the top-right corner.

The first value is the horizontal radius, the second the vertical radius.

If the second value is omitted it is copied from the first.

If either length is zero, the corner is square, not rounded.

Percentages for the horizontal radius refer to the width of the border box.

Percentages for the vertical radius refer to the height of the border box.
