Specificationhttps://drafts.csswg.org/css-cascade-5/#layering Design docs https://bit.ly/2SGjPlu Summary CSS cascade layers (@layer rule and layered @import syntax) provide a structured way to organize and balance concerns within a single origin. Rules within a single cascade layer cascade together without interleaving with style rules outside the layer. This allows authors to achieve a certain cascade ordering for same-origin rules in a proper way.

Interoperability risk is very low as WebKit and Gecko are also actively developing this new feature. Gecko: In development (https://bugzilla.mozilla.org/show_bug.cgi?id=1699215) WebKit: Shipped/Shipping (https://bugs.webkit.org/show_bug.cgi?id=220779) Web developers: Strongly positive ( https://bugs.chromium.org/p/chromium/issues/detail?id=1095765) Other signals: Debuggability @layer rules will be surfaced to DevTools in the Style panel to indicate which layer the style rules are in.
