We're a little constrained by the subset of css which the Qt library
supports. See https://doc.qt.io/qt-6/richtext-html-subset.html#css-properties
Unfortunately Qt CSS only supports font sizes in pt or px, not %. This
could be an enhancement which the QGIS project considers sponsoring in
Qt in future -- I can certainly see the limitation for a use case like
you describe!

So ... works but doesn't... That seems to be
surprising behaviour.
I can get that CSS style directives might not work the way one might hope
(that often happens to me in other circumstances...)
This is tempting me to experiment. Thanks for that!

Hi Chris,
yes I tried that. Any css-unit I could think of as well as em, % and code-words
(large). But only pt resulted in a visible change on the canvas.
Not sure if it is just not implemented or if it is a bug.

I suppose you tried style="font-size: 75%;" and maybe style="font-size:
0.75em;", and they did not work?
I wonder if, besides ..., you might have tried
...?

Ha!
I found an other way around to do the trick, suitable for my use case at least:
1) increasing the (overall) text size setting on the text tab by 2/3
2) putting only the attributes/text strings of the second and following lines
between ... tags, which renders them about 2/3 smaler, i.e. same as
before.
The (reverse) result is a multi line label with the first line emphazised by
its larger size! ;-)
"Bezeichnung" || 'D ' || round("Deckelhohe",2) || 'S

happy QGISing everyone!

Hi Stefan,
thanks for the hint.
The size value can be made variable (as visible in the expression builder
preview), but on the canvas there is yet no dynamic change what so ever. :-/

Re: [Qgis-user] Labeling: Allow HTML Formatting, text-size and map units
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(
'%2',
@fs , title( "Name" )))
Best regards
Stefan

Hi there!
I am just playing arund with html enhanced labeling, using the option "Allow HTML

Now I wonder how/if it is possible to override the text-size in such a manner,

Imagine you have a multi line label with the text size set to 2 meters map
units and a maximum scale at 1:5000.
Now the first line should be double in text size and therefore I use something like
style="font-size:20pt" (see example in manual above).
But only pt (points) seams to work as the unit in this place, which gives a
fixed size throughout all scales and does not respect the behavior of the map
units with maximum scale setting.
Does anyone know a trick to achieve this anyhow?
All the Best!
