Play around with changing some of the properties of ĬodePen Embed Fallback Taking things further ![]() Notice that the SVG is defined separately from the, and the simply references it. This SVG example creates a filter and renders a element that we can use for our grainy gradients. Bence Szabó explains it in much more detail as he demonstrates how it can be used to create patterns. It’s called and we can define attributes, such as whether it is “turbulence” or “noise” and how fine or coarse it is. Within the realm of SVG, we can define filters, and one such filter lets us create Perlin noise. Let’s go into detail on each of these parts. Blend gradients: Finally, we optionally use mix-blend-mode to further filter out colors and blend gradients together.Boost brightness and contrast: Then we turn to CSS filter to increase the brightness and contrast of the noise.Background with gradient and SVG: Next, we drop that filter into CSS as a background image that combines the filter with a CSS gradient.SVG turbulence: This is our noise filter.Here’s what we’re working with under the hood: Layer it underneath a gradient, boost the brightness and contrast, and that’s it - you have gradient that gradually dithers away. ![]() The trick is to use an SVG filter to create the noise, then apply that noise as a background. The core technique in this article is built on top of a Stack Overflow answer by Chris Pachl to the question: Can you add noise to a CSS gradient? The quickest way to understand what’s happening is to play with the parameters that make up the layers. Illustration by Jordan Kay on Dribbble Interactive playgroundĬheck it out here.
