I checked my usual css and found that I had to do the following to stop the footnotes from showing up as light grey:
Code:
a { font-style:normal; font-weight:normal; text-decoration:none;
colour:inherit; -webkit-text-fill-color:inherit; }
As I said before, I can't explain it, I just found it. Try colour:inherit; -webkit-text-fill-color:inherit;
