Snow falling on a canvas
npm install snowworkerLovely snow for your website. See a demo at https://snowfall.ooer.com/
Download /dist/snowfall.js and include it in your website somewhere. Then make anything that you want snow to settle on with a .rooftop class.
Alternatively clone the repo and use npm run start to run a webpack dev server instance on port 3000. This will watch for changes to the files in /src so you can tinker with it.
The snow isn't clever. It just lies on to of the element's clientRect. Ideally it should lie on the actual content, text, or whatever.
