Syntax
Note: The two length or percentage values of the border-top-left-radius property define the shape of the quarter ellipse that defines the border edge at the top-left corner. 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.
Value | Description |
---|---|
length | Defines the shape of the top-left corner. |
% | Defines the shape of the top-left corner using percentages. |
