dotCSS 2016 - Philip Walton - The Dark Side of Polyfilling CSS

Filmed at http://2016.dotcss.io on December 2nd in Paris. More talks on http://thedotpost.com Writing polyfills for CSS is much harder than it might seem. As a result, most polyfill authors today take shortcuts, which means the polyfills in widespread use are either too big, too slow, or too incorrect. Philip explores these challenges by writing a polyfill for a hypothetical new feature.
