We asked members of the CSS community to share their “pick of the year”

My 2021 Pick: “Building a Color Scheme” by Adam Argyle

I love this article because although custom properties have been around for a while now, it really takes them to a different level and showcases their power. I hope it makes some people think of them in a different way, as more than simple variables.
