The wiki supports inserting HTML into any wiki context.
HTML support is built-in, and does not require installing any additional packages.

For spans, you should rather use the Macro call syntax:Hello [[span(''WORLD'' (click [#world-anchor here]), style=color: green; font-size: 120%, id=world-anchor)]]!
Results in:Hello ''WORLD'' (click [#world-anchor here])!
