The blur()
CSS function applies a Gaussian blur to the input image. Its result is a <filter-function>
.
blur(radius)
radius
<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
.blur(0) /* No effect */ blur(8px) /* Blur with 8px radius */ blur(1.17rem) /* Blur with 1.17rem radius */
