    Introduction

    The border-start-start-radius CSS property defines a logical border radius on an element, which notes the size of the circle radius or the semi-major and semi-minor axes of the ellipse.

    In a horizontal-tb writing mode with LTR direction, it corresponds to the border-top-left-radius property. In a horizontal-tb writing mode with RTL direction, it corresponds to the border-top-right-radius property.

    Examples
