What exactly do you mean? Do you want the footnote to *look* like in Wikipedia (white on black at the bottom of the screen and bigger) or to *behave* like in Wikipedia (on click, not on hover, with a close button) or something else?
The basics of the core DokuWiki footnotes are similar enough but the Wikipedia version seems to be much more mobile-friendly.
