JavaScript Functions in CSS

I don't use a ton of math in my day to day life today but it's always been a little bit of a fun skill of mine what about functions here functions were great inside of SAS basically they function like a function you can pass in things. These things could be really great for a lot of the use cases that we talked about mix ins for right where you could pass into value and have some stuff spit out for it. Unfortunately Houdini has kind of just like I don't know it's not really a thing it is a thing but it's not a thing yeah it's bad.
