.footnotes-list targets the editor, and .markdown-preview-section .footnotes targets preview.
I don’t use footnotes often, so I haven’t settled on a final theme yet.
I made a small discovery. If you’d like to style them in tandem, use this:
.markdown-preview-section .footnotes, pre.HyperMD-footnote.CodeMirror-line {
font-size: 12px;
font-family: var(--font-monospace);
}
Again, .markdown-preview-section .footnotes targets preview
and pre.HyperMD-footnote.CodeMirror-line targets editor
I would change my first snips to these as well, since they target the elements more explicitly, so less chance of deprecation or crossover code from other things.
If you use a font-size, they will be the same. Or, use a % to scale them similarly, although they start at different sizes in core. You’d need to play with margins and padding if you want them identical.
