If you're using CSS cascade layers on your site, how are you handling support for older browsers these days? Do you still reach for a polyfill? Serve up a degraded visual experience? Nothing?

OddBirdCascade Layers – There's a Polyfill for That!Cascade layers are an exciting new addition to the CSS specification. A newly
released polyfill now provides even greater browser support for the feature.
@hexagoncircle I’m convinced it’s a paradigm shift bigger than the CSS grid layout was. Yes, it was possible to limit grids to support old IE or write a fallback flexbox layout, but most people chose to wait for full support. It was more practical in many ways. That’s my choice for cascade layers, too. I don’t like messy transpiled code or complicated polyfills: they don’t add user value, only change developer experience. It’s just not worth it, from my perspective.
