Hi Chris,
I hope it's not a big deal to bring this to the users list; in general I
prefer to answer CSS questions there so Google can help the next person to
have your problem ;)
Yes, the docs are a bit confusing. (It's a common trap for developers - in
SLD, styled marks rely heavily on nested XML structure, so finding a decent
way to encode this in CSS was kind of tricky. Then when I wrote up the
documentation I only gave an example of the most complicated case - using
multiple different symbols with different styling. If you have suggestions
on clarifying the documentation here I would be happy to incorporate some
edits.)
Anyway, for basic styled marks, it's fairly straightforward: you can think
of the mark as a new, polygon geometry and use stroke and fill parameters
for that. A rule with ":mark" in its selector will match these synthetic
geometries (":stroke", ":fill", and ":shield" work for geometries generated
for stroke patterns, fill patterns, and label shields respectively, and you
can also use ":symbol" to match any generated symbol.)
You need *at least two* rules: one to generate this synthetic geometry, and
one to style it (but as a convenience, if you don't style it it will have a
grey/black theme.)
* {
mark: symbol('circle');
}
* :mark {
fill: red;
stroke: black;
}
Or, specifically for the example you gave:
[@scale>34000000][@scale<69000000][longest_runway_ft>8000]{****
mark: symbol('circle');****
mark-size: 2;
halo-radius: 3;****
halo-color: #FFFFFF;****
label: [icao_identifier];****
label-offset: 0.0 0.0;****
label-anchor: 0 0.5;****
-gt-label-padding: 20;****
-gt-label-priority: [longest_runway_ft];****
}
[@scale>34000000][@scale<69000000][longest_runway_ft>8000]
:mark {
fill: #FF0000;
}
