the future of CSS: higher level custom properties to control multiple declarations
When using CSS Custom Properties we mainly use them directly as variables in calculations for other properties. Having one CSS Custom Property control a varying set of other properties — such as both colors and numbers — is not exactly possible. There are some hacky workarounds we can use, but these don’t cover all scenarios. Thankfully there’s a new idea popping up: Higher Level Custom Properties. Although still premature, these Higher Level Custom Properties would allow us to drop the hacks.
