Property definition and usage notes

The border-top-left-radius property defines the shape of the top-left border corner.

Syntax

Note:The two length or percentage values of the border-top-left-radius property define the shape of the outer border edge corner of a quarter ellipse. The first value is the horizontal radius, and the second is 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, while percentages for the vertical radius refer to the height of the border box.
