CSS radial-gradient() Function

<CSS函数参考

径向渐变与间隔均匀的色站:

#grad {
  background: -webkit-radial-gradient(red, green, blue); /* Safari 5.1- 6.0 */
  background: -o-radial-gradient(red, green, blue); /* Opera 11.6-12.0 */

CSS语法

background: radial-gradient( shape size at position, start-color, ..., last-color );
描述
shape 定义了渐变的形状。 可能的值:
  • 椭圆(default)
size 定义了梯度的大小。 可能的值:
  • 最远的角落(default)
  • 最接近端
  • 最近的角
  • 最远的端
position 定义了梯度的位置。 默认为"center"
start-color, ..., last-color 色标要渲染之间平滑过渡的颜色。 这个值由一个颜色值,后跟一个可选停止位置(a percentage between 0% and 100% or a length along the gradient axis)
