 Unlike linear gradients, you can specify the size of radial gradients. Possible values include `closest-corner`, `closest-side`, `farthest-corner`, and `farthest-side`, with `farthest-corner` being the default. Circles can also be sized with a length, and ellipses a length or percentage.

 This example uses the `closest-side` size value, which means the size is set by the distance from the starting point (the center) to the closest side of the enclosing box.

 This example uses `closest-side`, which makes the circle's radius to be the distance between the center of the gradient and the closest side. In this case the radius is the distance between the center and the bottom edge, because the gradient is placed 25% from the left and 25% from the bottom, and the div element's height is smaller than the width.
