CSSnano
cssnano has had some complicated ownership turnover[0], I'm glad to see someone took the mantle again though.
I do find that CSSO[1] with structural optimizations can be more effective still, perhaps that will be less true overtime though.
I think once lightning CSS is more stable (in particular, some bugs are addressed around ordering) it will be the clear winner in this space though.

If you’re using sass, it’s as straightforward as adding --style=compressed to your sass command.

Classic Themes with Block Patterns in WordPress
For the sake of simplicity, my example setup uses a single-file plugin and puts all styles directly into a single style.css file without using further theme.css or theme.json files, which we might want to use depending on the requirements for customizability. Likewise, SASS / SCSS support can be added if it makes life easier for the developer(s) involved. But as we already use PostCSS to control autoprefixing and cssnano minification, we can also use it to support the latest and even upcoming CSS sytax like native CSS nesting.
