I have been searching but I think nobody has asked about this (and it is strange). I consider too dark the color of the text on the footer but when I change it to any color it just ignores me. It workd when you change its size, but nor color. I still have access to your demo and it happens the same there.
Parallel to this, I see no difference between the "on dark" and "on light" version of the footer. Nothing changes. Maybe it has to do with the other problem. What should it do?
