Great, finally true CSS Variables in Webflow! Too bad that you cannot use them in Interactions yet. It seams that it is only possible to use standard css colors or HEX as of right now, but not the defined CSS Variables.
This is really important if you really want to use variables throughout the whole website, it was probably simply forgotten to add them to the interactions panel.
I don't understand why they'd launch variables and not have the capability to use them in interactions. Crazy! Kind of defeats the whole reason behind them
