> CSS didn't support constants and derived values for a long time, so a generation of web designers grew up thinking this is something quite difficult to achieve. I think it's more that design tools didn't used to support constants like this. Now tools like Figma do, designers are taking advantage of them and figuring out how to best to share constants/tokens with developers. Most web design is probably done by designers and not developers too, so it's not likely to be CSS variables (which have been available in CSS tooling like Sass for ages) that is driving this. I agree it doesn't need to be over complicated though.
