I'm creating some maps.
I have a layout of a site, with a number of devices around the site in the correct position. However its quite a large site, and when there is a fault the only way you can see this is by looking carefully and seeing the light red colour where the sensors are.
So I have an icon for the device, then a number of smaller icons below it with the name of the device. Only the bottom section goes red. I would like the background of the full icon to go a bright red so the eye is drawn immediately to it.
I have attempted the instructions here :
But this doesn't appear to work
