So, Chrome is currently prototyping CSS Functions.

I think that Firefox should also start experimenting with this feature.
Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.
Was just checking if there were any comments on CSS function support. Chrome and Edge support them at the moment, just waiting on Firefox and Safari to include support for them too.
Would be nice to see this feature supported.
