Oscar Cubo MedinaPor fin me he quitado de encima un potencial problema que me traía de cabeza. El tema de una aplicación crítica ahora se visualiza decentemente y es operativo en el #Webview que usa Microsoft en sus aplicaciones.
La solución es algo enrevesada: incluye un pipeline complejo con #gulp y #webpack usando #SASS, #PostCSS, transpilación de módulos JavaScript, un par de #polyfills, un #ponyfill, una pizca de magia arcana y varios artificios quirúrgicos. Dista de ser perfecta pero por lo menos es funcional.

foppaThis is mostly a question into the void, because I don't know how that's done in the real world.
When people are talking about #polyfills, in the context of #webdev, one argument that always pops up, is that they increase bundle size.
My thought: isn't it possible to dynamically load #javascript when a missing feature is detected in a browser? Does this incur a latency penalty that makes this unfeasible? Or is this actually a valid option?

Polyfilling CSS With CSS Parser Extensions, by @bramus:
Polyfilling CSS with CSS Parser Extensions
In April I attended #BlinkOn, the conference for web platform contributors in the Chromium open source project. At the conference I gave a presentation about “CSS Parser Extensions”, a wild idea I have to fix CSS polyfilling once and for all. If you didn’t know, polyfilling CSS features is extremely hard, mainly because the CSS Parser discards what it does not understand. So what if, instead of having authors write their own parser and cascade to polyfill a CSS feature, they could teach the parser some new tricks?
