<feGaussianBlur>
Baseline Widely available *
This feature is well established and works across many devices and browser versions. It’s been available across browsers since October 2018.
* Some parts of this feature may have varying levels of support.
The <feGaussianBlur> SVG filter primitive blurs the input image by the amount specified in stdDeviation, which defines the bell-curve.
Like other filter primitives, it handles color components in the linearRGB color space by default. You can use color-interpolation-filters to use sRGB instead.
