#css-custom-properties

Sometimes I want to set the value of a CSS property to that of a different property, even if I don't know what that value is, and even if it changes later. Unfortunately though, that's not possible (at least, there isn't a CSS function that specifically does that). In my opinion, it'd be super useful to have something like this (for interpolation, maybe you'd throw in there as well): /* Totally hypothetical */ button { border-radius: compute(height, self); border-radius: compute(height, inherit); border-radius: compute(height, #this); }
