If you have loads of annoying footnote# classes, wildcards might be a lazy option:
Code:
/* targets all class names beginning with footnote or fn *\
[class^="footnote"], [class^="fn"] {
--cr-hint: footnote-inpage;
}
which will apply the style to footnote, footnote1, footnote2, fn, fn1, fn2 etc.
But it'll also match to footnote-reference, fn-ref and other carelessly named classes, so YMMV as always and that's what we get for being lazy.
