Polyfill for animatable content properties on pseudo elements in non-supportive browsers (eg. Safari).
Safari doesn't support animatable psuedo elements just yet, this package remedies this with a sneaky polyfill. Just dump it in and your pseudo elements animated by your CSS should get going across platforms.
I use this on my personal site, to animate the dancing bars on the RTL Watch square for Safari.
Why not just use a gif? That's far less fun.
This is an npm package, download & require it like you normally would anything else. The package exports a listener to the DOM to get going once its safe to.
npm install pseudodo
This was built from a gist so its pretty rough, if you can improve it please contribute away!
