Cascade layers recently [end of 2024] reached the completely arbitrary “baseline widely available” milestone, which means they have been available across all modern browsers for more than 30 months now.
I’ve been a huge advocate of cascade layers since day one. I can’t imagine writing CSS without layers. So obviously I have a lot to say about layers. But today I want to focus only on one point (and it’s worth repeating): Your CSS reset should be placed inside a cascade layer.

I'm not a fan of reset style sheets and I won't use this one. But this might be a handy reference, nevertheless.
