[Qgis-user] Labeling: Allow HTML Formatting, text-size and map units

[Stefan Giese (WhereGroup)]

Hi Thomas,

you can try to involve the map_scale variable into a dynamic size of the 
HTML Label, something like:

with_variable('fs', 25000/@map_scale,
       format(
      '<h1 style="font-size:%1pt;">%2</h1>',
      @fs , title( "Name" )))

Best regards

Stefan
