CSS 径向渐变
A radial gradient is defined by its center.
To create a radial gradient you must also define at least two color stops.
句法
background-image: radial-gradient(shape sizeatposition, start-color, ..., last-color);
By default, shape is ellipse, size is farthest-corner, and position is center.

Use of Different Size Keywords
The size parameter defines the size of the gradient. It can take four values:
closest-side
farthest-side
closest-corner
farthest-corner
例子
A radial gradient with different size keywords:
#grad1 {
background-image: radial-gradient(closest-side at 60% 55%, red, yellow,
black);
}
#grad2 {
background-image: radial-gradient(farthest-side at 60%
55%, red, yellow, black);
}
