句法

blur(radius)
					

参数

radius
The radius of the blur, specified as a <length> . It defines the value of the standard deviation to the Gaussian function, i.e., how many pixels on the screen blend into each other; thus, a larger value will create more blur. A value of 0 leaves the input unchanged. The lacuna value for interpolation is 0 .

范例

blur(0)        /* No effect */
blur(8px)      /* Blur with 8px radius */
