Footnote rendering in Markdown




HTML generated by Markdown Extra (eg. as in Parsedown):

<sup id="fnref1:1">
    <a class="footnote-ref" href="#fn:1">1</a>

HTML generated by Multimarkdown (eg. as in Marked2):

<a href="#fn1" id="fnref1" title="see footnote" class="footnote" data-orig-id="fnref:1">1</a>

Markdown Extra looks more semantic but is harder to format.

Nice touch: tooltips in Multimarkdown – didn't test the „see footnote“ in other languages though.
Inline-footnotes are only possible via Multimarkdown.

Appropriate CommonMark thread.
