load-css-polyfill
A simple polyfill for asynchronously loading non-critical CSS using
link[rel=preload].
Introduction
Non-critical CSS can be loaded asynchronously by using
<link rel="preload" as="style"> with a onload handler that switches
rel="preload" to rel="stylesheet" once the file is loaded.
<link rel="preload" href="style.css" as="style" onload="this.rel='stylesheet'">
<noscript><link rel="stylesheet" href="style.css"></noscript>This package provides a polyfill for browsers which don't
support link[rel=preload] yet.
