Hi, I was wondering if anyone experienced in CSS and HTML could explain to me how the classes for changing reference pin colors were found? I imagine it was found using the inspecting tool, but the only thing I could find was in the following image.
What you have in the image is correct. Just combine those classes like this
.pin.icon.rem-reference__pin {
color: red;
}
which gives a red pin.
The meaning of this type of selector is explained in the Double Class Selector section in Multiple Class / ID and Class Selectors
