> Have you looked at Definitive CSS? It's up to date ... Not really, it doesn't talk about custom properties, inline svg, how to style them, etc. All very useful these days, if you want to allow color theming for your web app and not use hacks like custom fonts for icons... And custom properties are around since 2014 at the very least.
