The blur()
CSS function applies a Gaussian blur to the input image. Its result is a <filter-function>()
.
Syntax
blur(radius)
Parameters
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 of0
leaves the input unchanged. The initial value for interpolation is0
.
Examples
Setting a blur with pixels and with rem
blur(0) /* No effect */ blur(8px) /* Blur with 8px radius */ blur(1.17rem) /* Blur with 1.17rem radius */
