Hi. v-leaflet noob here.
In this thread, there have been many mentions of customising with CSS (I’m also CSS noob :). Can you give an example for me how this is done?
In my use-case, I would need to add a colored border to a marker.
Thanks in advance!
Ok, nevermind, got them working finally with horrendeus amount of poking around 
For anyone battling with the same issue here’s how it’s done:
String divIconString = “<img src="VAADIN/themes/mytheme/image.jpg" class="borderhighlight">”;
marker.setDivIcon(divIconString);
Where “borderhighlight” is the style you have done in your Vaadin theme CSS file.
But… I’m getting the same white square in the background as original poster mentions.
I tried to put
background-image: transparent;
and
background-color: transparent;
in the style, but to no effect.
A clumsy workaround:
Set the icon size to zero with
marker.setIconSize(new Point(0.0, 0.0));
but this still leaves a dot visible. So positioned the icon with CSS absolute positioning over the dot.
