Works for me, using alt.conf, the alternate colour scheme distributed
with Geany (note don't edit the system one, copy it into your
config/colorschemes directory, then you can delete it after you mess
it up :) change "comment_line=comment" to
"comment_line=comment,italic", save, and change to that scheme (note,
that means if its already selected change to something else then back,
schemes are only loaded when first selected), go to a tab with a
language with line comments, say C++, and viola italic line comments.

Colour schemes are not usually language specific, by default similar
syntactic elements eg comments, numbers, typenames are mapped by the
filetypes.xxx file to the same named style in all filetypes. This
makes multiple filetypes feel similar, you get used to "bold yellow is
a typename" no matter the filetype.
Hence the comment in the filetypes.css file (and most) to keep the
filetypes file as a mapping and let the colour scheme define the
actual style, not hard code style info in the filetypes file.
If you really wanted css to be different to all the other languages
you would need to ignore the above comment, but then colour schemes
would not work for css.

Selection isn't a lexical element style, its an editor style, so its
imposed over the lexical style, my comment really only applied to
lexical elements styles. Editor styles may have different semantics
since they do different things.

No, you can define a style, then define a different style to be the
previous one but also bold or italic as in the example I gave above.

There are a number of things that set the background colour or
otherwise affect the standard style, current line, selection, line
marker, search marker. These can overlap. If the colours are opaque
then only one will be shown for any piece of text or it may overwrite
the text. The translucency setting controls how the colours mix when
applied to the same text. The default value 256 uses some built in
mixing but set say the selection value (second number on the
"translucency=" line) to 255 and it hides everything because 255 means
opaque. Note that the "translucency=" line is in the [styling]
section of the file, its not in [named_styles] section, so its a
setting, not a named style and it may not be available in colour
The colours chosen for the selection by the style are mixed into the
display as controlled by the transparency. Thats what I meant above
when I cautioned that the semantics of editor styles differ from
lexical element styles because the editor styles are used in different
ways for different purposes.
