div.test1 { border-bottom-right-radius: 50px 25px;}

Notes

Specifies the radius of the bottom-right corner of an element.

When using『%』, the reference value is the element's size (border box).

You can set the horizontal and vertical radii individually by separating them with a space. The value before the space is the horizontal radius, and the value after is the vertical radius. This allows the corner to be rounded with an ellipse rather than a perfect circle. If the space is omitted, a uniform radius (perfect circle) is used.

/* div { border-bottom-right-radius: horizontal vertical;} */
div.test { border-bottom-right-radius: 50% 25%;}

Note that some older Android stock browsers have a bug where specifying a『%』value for『border-bottom-right-radius』may not render correctly.
